SK ABDUL HANIF

When computers first came out, they were as big as building rooms and had comparatively modest processing rates. Microprocessor technology led to a significant reduction in computer size and an increase in processing performance. Computers can be made in many different shapes and sizes with different processing powers, depending on their intended uses. In generally the computer systems can be classified on the following basis: Classifications of Computers System:-A. According to Size. B. According to Purposes. C. According to technology. A) According to Size Based on their outward size, internal capabilities, and external purposes, computers are divided into four classes. 1. Supercomputer 2. Mainframe computer 3. Minicomputer 4. Microcomputer SUPER COMPUTER The super computers are the most high performing system. A computer that performs better than a general-purpose computer is called a supercomputer. Supercomputer performance is usually measured in FLOPS (floating-point operations per second) instead of MIPS (million instructions per second). These are specially made to perform multi-specific tasks. Therefore, many CPUs work in parallel order on these supercomputers. This function of a Supercomputer is called Multiprocessing or Parallel Processing. The first supercomputer was created in the 1960s for the American Department of Defence (USA). All of the world's fastest 500 supercomputers run Linux-based operating systems. Supercomputers actually play an important role in the field of computation, and are used for intensive computation tasks in various fields. There are two broad categories of supercomputers: general purpose supercomputers and special purpose supercomputers. General purpose supercomputers can be further divided into three subcategories: 1) Vector processing supercomputers. 2) Tightly connected cluster computers. 3) Commodity computers. Supercomputers designed specifically to accomplish a specific task or objective are referred to as special purpose computers for the opposite reason. Application-Specific Integrated Circuits (ASICs) are usually used by them, and they provide higher performance.

A Computer is machine that performs tasks, such as calculations or electronic communication, under the control of a set of instructions called a program. Programs usually reside within the computer and are retrieved and processed by the computer’s electronics. The program results are stored or routed to output devices, such as video display monitors or printers. Computers perform a wide variety of activities reliably, accurately, and quickly.

Principal Mptc

There are a lot of terms used to describe computers. To put it in simple words a computer can be defined as an electronic device that processes instructions and produces an output to the user. To unveil the secret behind this process, understanding of individual components is important. Starting with the case, we'll discuss the role and functionalities of the various peripherals and hardware which are integral parts of the computer. What is a Computer? A machine that can be programmed to : Receive information. Process the information according to a set of suitable instructions. Display desired result information. A computer can also be used to store information whenever required It is a device capable of performing arithmetic and logical operations Computer-The Framework Types of computers Analog-An analog computer represents data as physical quantities and operates on the data by manipulating the quantities Digital-A computer that stores data in terms of digits (numbers) and proceeds in discrete steps from one state to the next Hybrid-Hybrid computers are made by combining features of analog computers and digital computers

This scientific article speaks about generations of computers, PC history, saving data, Von Neumann architecture, input/output peripherals, software instructions, programs, mainframe, minicomputers, microcomputers, supercomputers, libraries and operating systems, computer networks and Internet, introduction to the world of computers, evolution of computer systems, from the literature specialized in computer science. Computers are divided into: mechanical computers-water and gas meters, electromechanical computers-electricity meters, electronic computers (I generation of computers, II generation of computers, III generation of computers, IV generation of computers), optical computers and biological computers. After the highest prevalence, electronic computers are divided into: analogue-electronic computers, digital electronic-computers and hybrid electronic computers.

ICT IGCSE ch 1 & 11 Types of Computer

Objectives • identify different types of computer including: • Personal Computer or desktop • Mainframe • Laptop • Palmtop • Personal Digital Assistant

Computers come in all sorts of shapes and sizes. • You are all familiar desktop PCs and laptops, but did you know that computers can be as small as your mobile phone (in fact your phone is a computer!) and as large as a room?!

Mainframes • From their invention back in the 1940s until the late 1960s, computers were large, very expensive machines that took up the whole of a room (sometimes several!) These were the only computers available. • The circuit-boards of these computers were attached to large, metal racks or frames. This gave them the nickname 'mainframe' computers.

Mainframe Computer • A mainframe computer is a large computer, often used by large businesses, in government offices, or by universities.

Mainframe computers are typically: • Powerful - they can process vast amounts of data, very quickly • Large - they have to be kept in special, air-conditioned rooms • Multi-user - they allow several users (sometimes hundreds) to use the computer at the same time, connected via remote terminals (screens and keyboards)

Supercomputers • Some of the most powerful mainframe computers can process so much data in such a sort time, that they are referred to as 'supercomputers'

Personal Computer (PC) • The early 1980s saw a revolution in computing: the creation of computers that were small enough to fit on a desk, and cheap enough that everyone could have their own, personal computer, instead of having to share access to a mainframe.

These computers came to be known as desktop computers, or personal computers (PCs). • A typical PC contained the same basic components as a mainframe computer (CPU, RAM, storage, etc.) but at a fraction of the size and cost.

Early PCs… …were quite unlike the PCs that we all use today: • Displays were black and white, and only displayed text (no graphics) • No hard-drives (way too expensive) • Just a few 100 kB of RAM (not MB or GB!) • Slow - a typical speed would be 5MHz (not GHz!) • No mouse (no pointer to move!) • Light brown case (for some reason every early PC was brown!)

Because PCs were so much smaller than mainframe computers, they were called 'microcomputers' for a while

Laptop Computer • A 'laptop' computer is a light, compact and portable PC. • Laptops contain a rechargeable battery so that they can be used even when not plugged in to a mains power supply. • They also have a built-in LCD monitor. • Integrated keyboard and touchpad

To make them as portable as possible, most laptops try to avoid any sort of cable or wire. • Instead of a mouse, a trackpad(touchpad) is used. • Instead of a wired connection to a network or printer, 'wireless' radio connections are used.

Early portable computers were far from being 'laptops' • They weighed several kilos and would have crushed your legs!

Palmtop Computer • A palmtop computer is similar to a laptop computer, but smaller. It's small enough to fit in the palm of your hand (hence the name!) • Palmtops are usually not very powerful since fast CPUs require a large battery and get hot - both problems in a small device.

A typical palmtop has a very small keyboard - too small to type on normally. • Instead the user types using both thumbs. Also there is no room for a trackpad, so a touchscreen or tiny joystick is used instead.

Palmtops are extremely portable, but the small keyboard and screen make the devices tiring to use for long periods.

Personal Digital Assistant (PDA) • A PDA is similar to a palmtop computer, except it is even more compact, and typically has no keyboard • PDAs use a touchscreen for all data input.

Since the screen is so small, many PDAs have a small stylus (plastic stick) that is used to press things on the screen.

OCR input • Most PDAs use some sort of handwriting-recognition system to allow the user to write on the screen, and have their writing converted into text. • This is called Optical Character Recognition

Uses • PDAs tend to be used a 'digital diaries' allowing users to take their e-mail, documents, appointments, etc. with them wherever they go. • Alarms can be set to remind the user of appointments. You rarely see PDAs now since modern 'smart' phones can do all of this, and work as a phone too!

PDAs are often called Pocket-PCs • They have cut-down versions of Office software • Spreadsheet • Database • Word Processing • Presentation SW

Over to you: • Use the links on the wiki page (lesson 7) • Make notes • Complete the quizzes • Work through the interactive powerpoint presentation
