what is a computer assignment

• Assignment Statement

An Assignment statement is a statement that is used to set a value to the variable name in a program .

Assignment statement allows a variable to hold different types of values during its program lifespan. Another way of understanding an assignment statement is, it stores a value in the memory location which is denoted by a variable name.

The symbol used in an assignment statement is called as an operator . The symbol is ‘=’ .

Note: The Assignment Operator should never be used for Equality purpose which is double equal sign ‘==’.

The Basic Syntax of Assignment Statement in a programming language is :

variable = expression ;

variable = variable name

expression = it could be either a direct value or a math expression/formula or a function call

Few programming languages such as Java, C, C++ require data type to be specified for the variable, so that it is easy to allocate memory space and store those values during program execution.

data_type variable_name = value ;

In the above-given examples, Variable ‘a’ is assigned a value in the same statement as per its defined data type. A data type is only declared for Variable ‘b’. In the 3 rd line of code, Variable ‘a’ is reassigned the value 25. The 4 th line of code assigns the value for Variable ‘b’.

Assignment Statement Forms

This is one of the most common forms of Assignment Statements. Here the Variable name is defined, initialized, and assigned a value in the same statement. This form is generally used when we want to use the Variable quite a few times and we do not want to change its value very frequently.

Tuple Assignment

Generally, we use this form when we want to define and assign values for more than 1 variable at the same time. This saves time and is an easy method. Note that here every individual variable has a different value assigned to it.

(Code In Python)

Sequence Assignment

(Code in Python)

Multiple-target Assignment or Chain Assignment

In this format, a single value is assigned to two or more variables.

Augmented Assignment

In this format, we use the combination of mathematical expressions and values for the Variable. Other augmented Assignment forms are: &=, -=, **=, etc.

Few Rules for Assignment Statement

Few Rules to be followed while writing the Assignment Statements are:

• Variable names must begin with a letter, underscore, non-number character. Each language has its own conventions.
• The Data type defined and the variable value must match.
• A variable name once defined can only be used once in the program. You cannot define it again to store other types of value.
• If you assign a new value to an existing variable, it will overwrite the previous value and assign the new value.

November 22nd, 2022 | 6 min. read

Print/Save as PDF

High school computer teachers face a unique challenge. You have hundreds of students to teach, so planning lessons takes hours of personal time every week.

Creating computer applications lessons that are current, engaging, and will prepare your students isn’t easy! Unfortunately, it can be overwhelming to find computer applications lesson plans that are engaging and relevant to high schoolers.

So where do you start?

In this article, we’ll share where you can find great computer applications lesson plans to teach 5 topics to high school students:

• Digital Literacy
• Microsoft Office
• Google Applications
• Internet Research
• Computer Science

We’ll start with the basics — digital literacy.

1. Digital Literacy Resources for High School Computer Classes

Digital literacy (sometimes called computer literacy) encompasses a number of skills related to using technology effectively and appropriately, making it critical for your students to understand.

When teaching digital literacy in high school be sure to include these six topics:

• Information literacy
• Ethical use of digital resources
• Understanding digital footprints
• Protecting yourself online
• Handling digital communication
• Cyberbullying

All of this knowledge provides an important base that students build upon throughout the rest of your course and later in their education!

For digital literacy lesson plans and activities, check out these five steps to teaching digital literacy in the classroom .

2. Microsoft Office Lesson Plans for High School

Teaching Microsoft Office in high school is a must. While some students may be familiar with these programs, it’s critical to familiarize your students so everyone is on the same page.

Also, high school students can go more in-depth with the advanced features of each application, compared to middle school students.

You can find a ton of resources out there to build lesson plans, but there are almost too many for one person to read.

Instead, decide which Microsoft applications you will cover and go from there. Also, consider if your students will take Microsoft Office Specialist (MOS) certification exams. If so, include some exam prep lessons in your course.

To find lesson plan ideas that will work for your classroom, check out these Microsoft Office lesson plans that your students will love .

3. Google Apps Lesson Ideas for High School

Along with Microsoft Office, Google Apps are important for high school students to learn.

Your course standards may already include Google Apps, but if not, you should still consider including some lessons on Docs, Sheets, and Slides in your course.

It comes down to the fact that many employers are now using Google instead of Microsoft. That means your students should be prepared to use either application suite in their careers.

One way to teach Google Apps is to mirror your Microsoft Office lessons. Another option is to focus specifically on how the two suites differ, such as with the collaborative features in Google Docs.

Either way, you’ll need some lesson plans and activities!

To start, check out the Google Apps lesson plans every teacher should own .

4. Lessons to Teach Internet Research Skills in High School

Your students need internet research skills to use throughout the rest of their lives.

With the constant changes in how search engines work and the number of websites out there, these lessons are crucial.

Having good online research skills can help students prevent costly mistakes, such as citing false information in a final project or believing fake news.

There aren’t many resources about web research that are appropriate for high schoolers, but luckily Google has a series of lessons that could be just what you need.

There are three levels of expertise for each topic area, ensuring you can provide lessons based on your students’ levels of knowledge.

Additionally, some lessons have teacher presentations and Google includes a full lesson plan map for quick reference.

Check out the lessons from Google here: Search Literacy Lesson Plans .

5. Computer Science Lesson Plans for High School

Programming may be daunting to teach , but these skills are essential in today’s workforce. Knowing how to write code can set your students up for incredible careers in the future!

Help Articles

Programming assignments, learner help center dec 5, 2022 • knowledge, article details.

Programming assignments require you to write and run a computer program to solve a problem.

Some programming assignments count toward your final course grade, while others are just for practice.

Sections of a programming assignment

Programming assignments include both assignment instructions and assignment parts.

Assignment instructions:

• Explain the assignment.
• May include a link to a downloadable starter package that includes starter code, detailed guidelines, and other resources.

Assignment parts:

• Are similar to individual questions within a quiz.
• Are each a single coding task.
• Are each worth a certain number of points toward the overall assignment score.
• Can be completed and submitted all at once, or one at a time.

Programming assignment grades

Programming assignments are graded automatically.

Some are graded using a built-in grading algorithm that compares your program's output to a value specified by your instructor. Others are graded using a custom grading algorithm created by your instructor.

If a programming assignment uses built-in grading:

• Your code will run locally on your computer, and the output will be sent to Coursera's servers.
• Your grade will be based on comparison against numeric or regular expression grading logic.
• You'll get your grade a few seconds after submitting.

If a programming assignment uses custom grading:

• Your code will be run on Coursera's servers.
• Your grade will be based on custom logic provided by your instructor.
• You'll get your grade within an hour of submitting.
• You'll need to refresh the page to see your grade.

Submit a programming assignment

To submit a programming assignment:

• Open the assignment page for the assignment you want to submit.
• Read the assignment instructions and download any starter files.
• Finish the coding tasks in your local coding environment. Check the starter files and instructions when you need to.
• If the assignment uses script submission , submit your assignment by running the submission script in your local coding environment and entering the submission token.
• If the assignment uses web submission , upload your files using the instructions on your screen.

Test a programming assignment

Some programming assignments let you test them before you submit them to get feedback on whether they run. You won't get grades or feedback from the instructor until you submit the assignment.

Edit or resubmit a programming assignment

You can resubmit a programming assignment if you don't pass on the first attempt or want to improve your score. You might have to wait a certain amount of time between attempts.

To resubmit a programming assignment, follow the same steps for submitting one. If your assignment uses script submission, you'll need to select the Generate new token option on the assignment page and use the new submission token.

What is a Computer?

A computer is an electronic machine that processes raw data and outputs information. An electronic device that takes data as input and transforms it using a set of special instructions known as Programs to produce the desired output. A computer has an internal memory that stores data and instructions that are temporarily awaiting processing, as well as the intermediate result (information) before it is communicated to the recipients via the Output devices

What Does the Computer Require in Order to be Operational?

A Computer requires hardware devices and an operating system in order to be operational.

1. Hardware Devices

Monitor: It is a big television-like screen. It is an output device where you see what is happening on the computer.

Keyboard: It is an input device. It is a way of giving commands to a computer with the help of keys over it.

Central Processing Unit (CPU): It is a processing unit.It is considered the brain of the computer as it can’t perform any activity without CPU.

Mouse: It is an input device. This is the alternate method for cooperating with your PC. Most mice have two buttons — a right and a left button — and a looking over wheel.

Hardware Devices

2. Operating System (OS)

Operating System

PCs without an OS are precisely similar to TVs without a signal. They will turn on, yet you will be checking a clear screen out without any desire to collaborate with it. The most famous working framework is "Microsoft Windows," and it is used by most PC.

The OS acts as the sensory system of the PC, interfacing the computer processor to all the PC programs. The OS permits you to run other programs, work on projects, and do essentially all the other things that PCs are prepared to do.

There are a wide range of renditions of Microsoft Windows, and a new adaptation is delivered every several years.

How to Operate a Computer

There are three states in which a computer is at any given time.

OFF : This is precisely the exact thing it seems like: The PC is off, and no parts are running or working. The screen is dark (no pictures), there is no "humming" sound from the central processor, and the PC is inert to mouse developments or pressing keys on the keyboard. 

ON : When a PC is on, you ought to see pictures on the screen, conceivably hear a "buzzing" commotion coming from the central processor and the pointer on the screen ought to answer when you move the mouse.

Rest Mode : Most PCs have a mode called "Rest," in which the PC is on, yet has expected an energy-productive, insignificant power mode. To "wake" the PC, basically move the mouse around or press the spacebar on the console, and it will "awaken" and return to the identical spot that it was at the point at which it fell asleep.

Signing on Screen

When you turn the PC on, the PC will go through a progression of mechanized undertakings before it is prepared for you to associate with it; this cycle is called "startup." This cycle will endure somewhere in the range of one and two minutes. Assuming the PC is not working accurately, you might see a blunder message during startup.

After you sign on, the PC will show what is known as your work area inside a couple of moments to a couple of moments. Here you will see a computerized portrayal of something almost identical to real-life office space, complete with a work area, documents and record organizers, and a recycling bin.

Features of Computer

Below mentioned are some of the features of a computer..

When executing mathematical computations, a computer works significantly faster and more accurately than a human.

Speed of Computer

Calculations made by computers are always accurate. Data inaccuracy or consistency might lead to errors.

A computer contains internal storage for data called main memory. Data is also stored on removable media like CDs, pen drives, and other types of secondary storage.

Computer Memory

Reliability

When given the same set of data repeatedly, a computer will consistently provide the same output, demonstrating its dependability.

The computer completes every task automatically, that is, without human interaction.

Computer Automation

Drawbacks of Computer

Although using a computer has numerous benefits, there are also risks and drawbacks. If used improperly, computers can cause a number of health problems.

The computer is emotionless.

It can't function alone. It requires somebody to work on it and give it instructions.

The computer must be supplied with each command.

No choice can be made by a computer on its own.

What is a Machine?

A machine is a tool that facilitates our job.

It helps us save time and effort.

Humans are not as productive as machines .

Machine Examples Include the Following:

For enjoyment, people use televisions.

To iron the clothes, use an iron box.

An automobile is used for transportation.

Calling is done on a mobile device.

Mobile Device

Points to Remember 

Computer is an electronic machine.

The main components required for a computer are mouse, monitor and  keyboard.

The CPU is also known as the “Brain” of the computer.

OS stands for operating system.

The first screen you see when it starts is called the desktop.

Learning by Doing

Choose the correct answer:.

1. Which part of the computer contains the computer's brains?

B. Keyboard

D. All of above

Write True or False

1. Windows, Linux, and Android are examples of Operating devices(True/False)

2. Keyboard is an Input device. (True/False)

Sample Questions

1. Choose the correct statement

A. Computer is an electronic machine

B. It performs arithmetic operation

C. Both A) and B)

2.  What is an OS? 

Ans: OS stands for operating system.The OS permits you to run other programs, work on projects, and do essentially all the other things that PCs are prepared to do.

3. List various primary parts of the computer.

1. A Motherboard

2. A CPU i.e. Central Processing Unit’

3. RAM i.e. Random Access Memory

5. Hard drives

6. Computer Mouse

The monitor, CPU, keyboard, mouse, printer, sound system, RAM, hard drive, and many other components make up the computer system's hardware. There are various operating systems in computers such as Microsoft Windows, Linux and so on.

FAQs on Introduction to Computer

1. Which OS does Apple use?

An Apple Computer is called a Macintosh (Mac). Its Operating System is OS X while other PCs use windows.

2. Do computers require the Internet to operate?

A computer does not need to access the Internet in order to run properly. The Internet is a way of connecting to other computer users. You can interface with the web utilizing a telephone line, a link association, or by utilizing a remote interfacing gadget (wi-fi). For most home PC clients, this is a paid help, however you can use the Web for free in a few public areas, similar to the library or a café. A PC will actually want to carry out most normal roles (play music, type records, alter pictures) and run programs without a Web association. Notwithstanding, to see a page or send an email, you will require a Web association. 

3. What “My Computer is Possessed!” means?

“My Computer is Possessed!” It is a common misconception that computers have “a mind of their own.” In spite of the fact that PCs can play out specific assignments significantly more effectively and quicker than people (like counting, performing numerical computations, and so on), they are, eventually, machines and can't have an independent mind. Any reasonable person would agree that the PC can do nothing that you don't advise it to do.

Learning programming languages

Strategies for programming assignments, citing code.

Coding assignments can range from simple programs to full-blown applications. It is important to know how to approach such assignments, so that you can complete them to the best of your ability. Some platforms you may be asked to develop for are:

• Web  — websites and web apps for browsers like Chrome or Firefox
• Mobile  — mobile apps for iOS and Android
• Desktop  — desktop applications or programs for Windows, macOS and Linux.

If you are starting a coding assignment in a programming language that you are not familiar with, there are tutorials you can take to understand the basics in a few hours:

• Learn a range of  programming language training and tutorials  from LinkedIn Learning (UQ login is required)
• Codecademy  has courses on web development, data science and computer science
• w3schools  has tutorials on web development languages — HTML, CSS, JavaScript, Python etc.

Get more information on  tools for web, software and mobile application development .

Universal strategies that can be applied to make your programming assignments easier:

• Start early  — this gives you more time to think about the task and how you might approach it, but also more time to get help, if needed
• Plan your program using pseudocode  —  pseudocode  is a great method for planning what you want to code in way that is easy for people to understand
• Create the HTML, CSS and JavaScript files
• Link the CSS and JavaScript files using the appropriate tags in your HTML file.
• Use comments  — all programming languages allow you to write comments that are lines which are ignored by the program. A great way to use comments is to type out the steps required for coding a piece of functionality. You can then follow these steps to code it line by line
• Take a break  — if you ever get stuck, it’s probably a good time to take a break. Breaks as short as 5 minutes can be enough to clear your mind
• Explain your problems to a rubber duck  —  Rubber duck debugging  is actually a legitimate way of solving programming related problems. It works simply by explaining your problems aloud, which can help you find what’s causing bugs in your code.

Students should confirm what is permitted for a specific assignment prior to commencing. Some assignments do not permit the use of external support and all code must be written by the individual. However, if you are allowed to use externally sourced code it must be referenced if it is not your own original work. Failure to reference externally sourced, non-original work can result in misconduct proceedings. An external source is code, including from anywhere on the internet or from a tutorial, taken or used to write your own code.

References should provide clear and accurate information for each source and should identify where they have been used in your work. A single URL is not a complete or accurate reference. URLs should link directly to the work cited, not just to the website it is hosted on. An example format for referencing online sources:

[where used] : [title of asset], [creator of asset]; retrieved from [website title] ([URL]), Last accessed [DD/MM/YYYY}

For code references, the [where used] should map to the position in the code e.g. in the code itself, create a comment to identify where in your code you have used an external source:

For code with no changes or adaptations

(How to comment) retrieved from Unity Answers : how to comment the lines? (http://answers.unity3d.com/answers/221574/view.html target=”_blank” rel=”noopener noreferrer”) Last accessed 11/9/2017

Ensure you are using syntax specifically for the programming language being used.

For code that you have changed or adapted

You should describe how you adapted it.

Computer Basics: Basic Parts of a Computer

Lesson 3: basic parts of a computer.

/en/computerbasics/what-is-a-computer/content/

Introduction

The basic parts of a desktop computer are the computer case , monitor , keyboard , mouse , and power cord . Each part plays an important role whenever you use a computer.

Watch the video below to learn about the basic parts of a computer.

Looking for the old version of this video? You can still view it here .

Computer case

The computer case is the metal and plastic box that contains the main components of the computer, including the motherboard, central processing unit (CPU), and power supply. The front of the case usually has an On/Off button and one or more optical drives .

Computer cases come in different shapes and sizes. A desktop case lies flat on a desk, and the monitor usually sits on top of it. A tower case is tall and sits next to the monitor or on the floor. All-in-one computers come with the internal components built into the monitor, which eliminates the need for a separate case.

The monitor works with a video card , located inside the computer case, to display images and text on the screen. Most monitors have control buttons that allow you to change your monitor's display settings, and some monitors also have built-in speakers.

Newer monitors usually have LCD (liquid crystal display) or LED (light-emitting diode) displays. These can be made very thin, and they are often called flat-panel displays . Older monitors use CRT (cathode ray tube) displays. CRT monitors are much larger and heavier, and they take up more desk space.

The keyboard is one of the main ways to communicate with a computer. There are many different types of keyboards, but most are very similar and allow you to accomplish the same basic tasks.

Click the buttons in the interactive below to learn about the different parts of the keyboard.

Print Screen, Scroll Lock, Pause/Break

The Print Screen , Scroll Lock , and Pause/Break keys are at the top-right corner of the keyboard. The Print Screen key takes a picture of your screen (called a screenshot) that you can edit or save using a graphics program. Scroll Lock and Pause/Break are rarely used today, so some keyboards don't have them.

The Escape (Esc) key allows you to stop a function or action. For example, if a webpage is taking a long time to load, you can press the Escape key to stop loading it.

Function Keys

The function keys are labeled F1 through F12 . Some programs use these keys as shortcuts for common tasks. For example, in many programs, F1 opens the Help file.

The Tab key is used to create indents in word processing programs. Also, if you are filling out a form online, you can use the Tab key to switch to the next field.

Alphanumeric Keys

The main part of the keyboard includes the alphanumeric keys ( letters and numbers ) and the spacebar .

Ctrl, Alt, and Shift

The Control (Ctrl), Alternate (Alt), and Shift keys are designed to work in combination with other keys. Typically, you hold down Ctrl, Alt, or Shift and then type another key to perform a specific task. For example, in many programs, typing Ctrl+S will save a file.

The arrow keys are used for many different purposes, including moving the cursor, scrolling a document, and controlling a game.

Numeric Keypad

The numeric keypad resembles a calculator keypad. Many users find that it is easier to type numbers using this keypad. On some keyboards, these keys double as arrow keys.

Backspace Key

The Backspace key (also known as the delete key) erases the character to the left of the cursor.

The Enter key (also known as the return key) executes commands. For example, while on the Internet, you can type a website address and then press Enter to go to the site. It is also used to start a new line in word processing programs.

Home and End

These move the cursor to the beginning or end of the current line.

Insert and Delete

Insert : This switches between insert mode (which inserts new text without deleting anything) and overtype mode (which deletes text after the cursor as you type). Delete : This erases the character to the right of the cursor.

Page Up and Page Down

These scroll a document or webpage up or down.

If you want to learn how to type or improve your touch-typing skills, check out our free Typing Tutorial .

There are two main mouse types: optical and mechanical. The optical mouse uses an electronic eye to detect movement and is easier to clean. The mechanical mouse uses a rolling ball to detect movement and requires regular cleaning to work properly.

To learn the basics of using a mouse, check out our interactive Mouse Tutorial .

Mouse alternatives

There are other devices that can do the same thing as a mouse. Many people find them easier to use, and they also require less desk space than a traditional mouse. The most common mouse alternatives are below.

• Trackball : A trackball has a ball that can rotate freely. Instead of moving the device like a mouse, you can roll the ball with your thumb to move the pointer.

What Is An Assignment In Computer Science

Table of Contents:

Assignment – This definition explains the meaning of Assignment and why it matters.

An assignment is a statement in computer programming that is used to set a value to a variable name. The operator used to do assignment is denoted with an equal sign (=). This operand works by assigning the value on the right-hand side of the operand to the operand on the left-hand side.

Assignment (computer science)

Certain use patterns are very common, and thus often have special syntax to support them. These are primarily syntactic sugar to reduce redundancy in the source code, but also assists readers of the code in understanding the programmer’s intent, and provides the compiler with a clue to possible optimization.

Today, probably the most generally used notation with this operation is x = expr (initially Superplan 1949–51, popularized by Fortran 1957 and C). The 2nd most generally used notation is(1) x := expr (initially ALGOL 1958, popularised by Pascal). A number of other notations will also be being used. In certain languages, the symbol used is considered being an operator (and therefore a job statement in general returns something). Other languages define assignment like a statement (and therefore it can’t be utilized within an expression).

In computer programming, an assignment statement sets or re-sets the value stored in the storage location(s) denoted by a variable name. In most imperative computer programming languages, assignment statements are one of the basic statements. Common notations for the assignment operator are = and :=.

Any assignment that changes an existing value (e. g. x := x + 1) is disallowed in purely functional languages. In functional programming, assignment is discouraged in favor of single assignment, also called name binding or initialization. Single assignment differs from assignment as described in this article in that it can only be made once, usually when the variable is created; no subsequent re-assignment is allowed. Once created by single assignment, named values are not variables but immutable objects.

Overview – The assignment operator allows us to change the value of a modifiable data object (for beginning programmers this typically means a variable). It is associated with the concept of moving a value into the storage location (again usually a variable). Within most programming languages the symbol used for assignment is the equal symbol. But bite your tongue, when you see the = symbol you need to start thinking: assignment. The assignment operator has two operands. The one to the left of the operator is usually an identifier name for a variable. The one to the right of the operator is a value.

In computer programming, an assignment statement sets and/or re-sets the value stored in the storage location(s) denoted by a variable name; in other words, it copies a value into the variable. In most imperative programming languages, the assignment statement (or expression) is a fundamental construct. (en)

In computer programming, an assignment statement sets and/or re-sets the value stored in the storage location(s) denoted by a variable name; in other words, it copies a value into the variable. In most imperative programming languages, the assignment statement (or expression) is a fundamental construct. Today, the most commonly used notation for this operation is x = expr (originally Superplan 1949–51, popularized by Fortran 1957 and C). The second most commonly used notation is x := expr (originally ALGOL 1958, popularised by Pascal),. Many other notations are also in use. In some languages, the symbol used is regarded as an operator (meaning that the assignment statement as a whole returns a value). Other languages define assignment as a statement (meaning that it cannot be used in an expression). Assignments typically allow a variable to hold different values at different times during its life-span and scope. However, some languages (primarily strictly functional languages) do not allow that kind of “destructive” reassignment, as it might imply changes of non-local state.

1 QUESTION 1 Computer-programming. Computer-programming is definitely an science and art, of giving a mechanism or computer, the directions or instructions to follow along with to resolve an issue or accomplish an activity. QUESTION 2 Variations BETWEEN EVENT-DRIVEN AND OBJECT-ORIENTED AND PROCEDURAL PROGRAMMING LANGUAGES. To say the least, in the event-Driven the flow of Control is dependent upon occasions triggered through the user, (click of the mouse), although Object-Oriented Programming necessitates the programmer to pay attention to the objects the program may use to complete its goal. Finally, in Procedural Oriented Programming, the programmer only focuses on the main tasks the program must perform step-by-step. The flow of control for that program is dependent upon occasions mostly triggered by users. That’s, execution is decided for instance with a user action for example click, keypress, or perhaps a message in the Operating-system (OS) or any other user. Visual Basics and Visual C++ are specifically made to facilitate event-driven programming and supply a built-in development atmosphere (IDE) that partly automates producing code.

What is an assignment in computer science example?

An assignment is a statement in computer programming that is used to set a value to a variable name . The operator used to do assignment is denoted with an equal sign (=). This operand works by assigning the value on the right-hand side of the operand to the operand on the left-hand side.

What does assignment mean in programming?

In order to change the data value stored in a variable , you use an operation called assignment. This causes the value to be copied into a memory location, overwriting what was in there before. Different values may be assigned to a variable at different times during the execution of a program.

What is assignment in Python?

An assignment statement evaluates the expression list (remember that this can be a single expression or a comma-separated list, the latter yielding a tuple) and assigns the single resulting object to each of the target lists, from left to right.

What is an assignment statement explain with an example?

An assignment statement gives a value to a variable . For example, x = 5; ... the variable may be a simple name, or an indexed location in an array, or a field (instance variable) of an object, or a static field of a class; and. the expression must result in a value that is compatible with the type of the variable .

What is an assignment in Java?

Assignment in Java is the process of giving a value to a primitive-type variable or giving an object reference to an object-type variable . The equals sign acts as assignment operator in Java, followed by the value to assign.

A computer is an electronic device that can process and store information. It can perform calculations, manipulate data, and execute instructions to accomplish specific tasks. The basic components of a computer include the central processing unit (CPU), memory (RAM), storage (hard drive or solid-state drive), input devices (keyboard, mouse, etc.), output devices (monitor, printer, etc.), and various peripheral devices (such as USB drives or external hard drives).

What is CPU?

The CPU is often considered the brain of the computer, as it performs most of the processing and calculations required for a computer to function. RAM is the temporary memory that stores data and instructions while the computer is running, while storage is the long-term memory where data is stored even when the computer is turned off.

Input devices allow users to input data or commands into the computer, while output devices display the results of the computer’s processing. Peripheral devices are additional components that can be added to a computer to enhance its functionality.

A computer is an electronic device that can perform tasks based on instructions provided to it. It consists of hardware components such as the central processing unit ( CPU ), memory, input/output devices, and storage devices.

The CPU is the brain of the computer and performs the bulk of the processing tasks. Memory, also known as RAM , is where data and instructions are temporarily stored while the computer is running. Input/output devices, such as a keyboard, mouse, and monitor, allow users to interact with the computer and receive information from it. Storage devices, such as a hard drive or solid-state drive, store data and programs permanently on the computer.

Computers can run different types of software, including operating systems, applications, and games. They can also be connected to the internet and used to access online services, communicate with other people, and share information.

Overall, computers are incredibly versatile machines that have become an integral part of modern life, used for work, entertainment, education, and many other purposes.

The computer is a device that makes our work easy. The computer is a device that helps us to complete our tasks easily and speedily. Computer doesn’t have a brain like human beings. We have to give them instructions on what to do when a particular situation arises. We have to tell them everything from what to expect for data(what type of data), how to process it(how to perform calculations) to where to store the data. We humans understand language that is composed of words which further is composed of letters. But, the computers don’t understand our language nor the words like “hello, good morning, discipline, etc”. They only understand binary language whose vocabulary contains only two letters or states or symbols i.e. 0 and 1, True and False, On and Off. To maintain the state transistors are used.

• Transistors are tiny devices that are used to store 2 values 1 and 0 or on and off.
• If the transistor is on we say that it has a value of 1, and if it is off the value is 0.

For example, a memory chip contains hundreds of millions or even billions of transistors, each of which can be switched on or off individually. As a transistor can store 2 distinct values, we can have millions of different values stored on a memory chip consisting entirely of 0’s and 1s. But how does a transistor get its value? When a very little amount of electric current passes through the transistor it maintains the state of 1 and when there is no electric current then the transistor has the state of 0. 

Then how it’s all connected to the computer?  

These 0’s and 1’s form the building block of a computer. With the combinations of 0 and 1, we create a whole new language For example, 0 can be written as 0,

Hello World! as,

And so on… So now the question arises how can a human remember this code?

It seems impossible!

Well, we humans can do everything that we desire and this code can be remembered very easily but we don’t have to remember. We just have to use our language and the software (also built by humans) converts our normal letters into binary language.

What is software?

Software is a set of instructions that tells the computer what to do, when to do, and how to do it. Examples are, the paint that we use in Microsoft, WhatsApp, and games, all are types of different software. Suppose we want to add 2 numbers and want to know what 2 + 2 is 4. Then we must give the computer instructions,

• Step-1: take 2 values.
• Step-2: a store that 2 value
• Step-3: add 2 value by using + operator
• Step-4: save the answer

Separate instructions are provided for the + operator so the computer knows how to do addition when it encounters the + sign. So who converts this code? Instead of who we can ask what converts the code. And answer to that question is a software called interpreter that interprets our language code into binary code. The interpreter converts our code into machine language that can be understood by the computer. 

Now the question is how we give our input.  

We give our input with the use of hardware for example like scanner, keyboard, and mouse(not the one that eats cheese). When we give input through hardware, the software interprets it into machine language and then it is processed and our output is shown. 

Process: If we want to display the letter ‘A’ on the screen we first will open the notepad. Then we will press the Capslock key or shift key to make the letter capital, after that, we will press the letter ‘a’. And our screen will show the letter ‘A’. 

Under the hood process: When we pressed the capslock or shift key the software tells us that whatever follows this should be printed on the screen and after we have pressed the letter a which is a small letter, the software first converts it into binary like it had converted the shift or capslock key and then after the computer understands it prints A on the screen.

Related Concepts of Simple Understanding 

Some related concepts that can help in understanding computers include:

• Binary code: Computers communicate and process information using a binary code, which is a system of ones and zeroes. Each binary digit (or bit) represents a simple “on” or “off” state, and combinations of bits can represent more complex information.

Course Overview

This course focuses on computer security, covering a wide range of topics on both the defensive and offensive side of this field. Among these will be systems security and exploitation (e.g., buffer overflows and return-oriented programming), sandboxing and isolation, side channels, network security, cryptography, privacy and anonymity, and legal and ethical issues. The goal of the course is to provide an appreciation of how to think adversarially with respect to computer systems as well as an appreciation of how to reason about attacks and defenses.

To complete the projects in this course, you will need to be able to write code in Python, C, and (some) C++, and have some understanding of x86 assembly, JavaScript, PHP, and SQL. We will not teach these in lecture; you are expected to learn them on your own or ask for help in section or office hours.

Pandemic Considerations

This is an in person class. Exams are in person only. Please do not come to class or exams if you are sick.

Assignments

We will have five programming assignments. These assignments are meant to both reinforce your knowledge of the concepts covered in lecture and get you to think about security in more depth, beyond what is covered lecture.

You may work on the assignments in groups of one or two. You may discuss the assignments with other students from the course in general but not any specific solution. You will have two late days you can use to turn in assignments late for any reason. Late days will be deducted from both group members, and both group members must have late days in order to use them. No other extensions will be given. If you have an unforeseen long-term emergency that affects all of your classes (hospitalized, death of immediate family member etc.), please reach out to us and the student affairs office to coordinate alternate arrangements.

If you consult anything (books, academic papers, internet resources, people) when working on the assignments, note this in your submission. We encourage outside learning but expect you to not seek out specific details about a solution—anything submitted should be considered your own work. Similarly, you are expected to not publish or otherwise share your solutions at any point (even after the class is over). If you are unsure about what is allowed, please ask the course staff.

By taking this course, you implicitly agree to abide by the UCSD policies on Integrity of Scholarship and Student Conduct . See the Academic Integrity Support for Remote Learning . University rules on integrity of scholarship and code of conduct are taken seriously and will be enforced.

• Administering Pricing

Assign Pricing Strategy According to Customer

Assign the pricing strategy according to the value that you set in the Customer attribute on each sales order.

You can assign a different strategy for each customer according to the customer number or the customer name.

Assume you want to assign a different strategy for each customer according to the customer number.

If the segment is Tier 1 and the customer is Computer Service and Rentals, then assign the Commercial pricing strategy.

If the segment is Tier 1 and the customer is ABC Telecommunications, then assign the Corporate pricing strategy.

Assigning the pricing strategy according to customer is similar to assigning according to business unit. Do the set up described in the Assign Pricing Strategy According to Business Unit topic, but with these following important differences:

Get the customer number. Skip this step if you need to assign according to customer name.

Modify the matrix class.

Modify the strategy assignment.

Modify the service mapping.

Get the Customer Number

You will reference the customer number instead of the customer name because the number is unique. Using the number helps to avoid problems when you have the same customer name in more than one customer record.

Use the Manage Customers task to get the customer numbers. Assume you identify the numbers.

For details, see Display Account Details on Sales Orders .

Modify the Matrix Class

Modify the matrix class so you can set the customer in the strategy assignment.

Go to the Pricing Administration work area, then click Tasks > Manage Matrix Classes .

On the Manage Matrix Classes page, in the Name column, click Sales Pricing Strategy Assignment .

On the Edit Matrix Class page, in the Condition Columns area, click Actions > Add Row , then set the values.

To set the Domain, click the pencil in the Domain column, then set the values in the Edit Column Domain Values dialog. Set them in the same sequence that this table displays them.

Leave all other attributes empty.

Modify the Strategy Assignment

Next, modify the strategy assignment.

Click Tasks > Manage Pricing Strategy Assignments .

On the Manage Pricing Strategy Assignments page, click Actions > Add Row , set the values, then click Save .

Click Create Assignment Matrix .

In the Create Assignment Matrix dialog, in the Select Optional Condition Columns area, set the values, then click OK .

In the Pricing Strategy Assignment Rules area, create 2 rows.

Continue with the rest of the work described in the Assign Pricing Strategy According to Business Unit topic, such as modifying the pricing algorithm and testing your set up.

Title: ita-ecbs: a bounded-suboptimal algorithm for combined target-assignment and path-finding problem.

Abstract: Multi-Agent Path Finding (MAPF), i.e., finding collision-free paths for multiple robots, plays a critical role in many applications. Sometimes, assigning a specific target to each agent also presents a challenge. The Combined Target-Assignment and Path-Finding (TAPF) problem, a variant of MAPF, requires simultaneously assigning targets to agents and planning collision-free paths. Several algorithms, including CBM, CBS-TA, and ITA-CBS, can optimally solve the TAPF problem, with ITA-CBS being the leading method of flowtime. However, the only existing suboptimal method ECBS-TA, is derived from CBS-TA rather than ITA-CBS, and adapting the optimal ITA-CBS method to its bounded-suboptimal variant is a challenge due to the variability of target assignment solutions in different search nodes. We introduce ITA-ECBS as the first bounded-suboptimal variant of ITA-CBS. ITA-ECBS employs focal search to enhance efficiency and determines target assignments based on a new lower bound matrix. We show that ITA-ECBS outperforms the baseline method ECBS-TA in 87.42% of 54,033 test cases.

According to the complex characteristics of the mutual influence of passenger flows between different train adjustment schemes, a computer-aided train service plan adjustment optimization model based on passenger flow assignment is proposed with the goal of minimizing the remaining passenger turnover. The actual operating effects of trains and the impact between different adjustment measures and between trains are also considered. A computer iterative optimization algorithm with 2 stages based on the greedy principle is designed. The computer processing is divided into two stages: train adjustment plan selection and passenger flow information analysis. The selection of adjustment schemes is feedback-corrected based on the results of passenger flow assignment. Finally, taking the train operation plan of the Beijing-Shanghai high-speed railway as the research object, an example is demonstrated, and the results show that the model and algorithm can effectively obtain the optimal train adjustment scheme under the current conditions.
