Long and Short Computer Essay

The term computer was once used to refer to a person who did computation, unlike today. The development of early prototypes that led to the modern computer is credited to many individuals throughout history. A series of breakthroughs, beginning with transistor computers and then integrated circuit computers, resulted in the development of transistor technology and the integrated circuit chip, causing digital computers to largely replace analogue computers. 

In this essay, we will discuss the various components and types of computers and talk about their uses in various fields.

Long Computer Essay in English

A computer is an electronic tool that manipulates data or information. It can store, retrieve, and process information. We can type documents, send emails, play games, and browse the Web using a computer. It can also be used to edit spreadsheets, presentations, and even videos, or create them. 

Early computers were conceived only as devices for calculating. Simple manual devices such as the abacus have helped individuals do calculations since ancient times. Some mechanical devices were built early in the Industrial Revolution to automate long, tedious tasks, such as guiding patterns for looms. In the early 20th century, more sophisticated electrical machines performed specialized analogue calculations. 

Common Components of Computers

All those parts of a computer that are tangible physical objects are covered under the term hardware. The hardware includes circuits, computer chips, graphics cards, sound cards, memory (RAM), motherboards, displays, power supplies, cables, keyboards, printers and "mice" input devices.

 There are five main hardware components: 

Input Devices: 

These are devices that are used to enter data/information in the central processing unit. Example- keyboard, mouse, scanner, document reader, barcode reader, optical character reader, magnetic reader etc.

Output Devices: 

These are devices that provide the processed data/information into human-readable form. Example- monitor, printer, speaker, projector etc.

Control Unit: 

The control unit handles the various components of the computer; it reads and interprets (decodes) the instructions for the program, transforming them into control signals that activate other computer parts.

Arithmetic Logic Unit: 

It is capable of performing arithmetical and logical functions. The set of arithmetic operations supported by a specific ALU may be restricted to addition and subtraction or may include functions of multiplication, division, trigonometries such as sine, cosine, etc., and square roots.

Central Processing Unit: 

The ALU, control unit and registers and together called the CPU. It is sometimes called the computer's brain, and its job is to perform commands. We send instructions to the CPU whenever we press a key, click the mouse, or start an application.

Software refers to computer parts, such as programs, data, protocols, etc., that do not have a material form. In contrast to the physical hardware from which the system is built, the software is that portion of a computer system consisting of encoded information or computer instructions.

It is sometimes called "firmware" when the software is stored in hardware that can not be easily modified, such as with a BIOS ROM on an IBM PC compatible computer.

Computer hardware and software require each other, and neither of them can be realistically used on their own. There are four main components of a general-purpose computer: the arithmetic logic unit (ALU), the control unit, the memory, and the I/O (collectively called input and output) devices.

Uses of Computer

Computers are used in various fields, such as homes, businesses, government offices, research organizations, educational institutions, medicine, entertainment, etc. because of their features and powerful functions. They have taken sectors and companies to a whole new level.

Science- 

Computers are best suited for the collection, analysis, categorization, and storage of data in science, research and engineering. They also help scientists to exchange data both internally and internationally with each other.

Government-

In most cases, data processing tasks, the maintenance of citizens' databases, and the promotion of a paperless environment are the primary purposes of using computers. In addition to this, computers play a key role in the country's defence system.

Health and Medicine- 

They are used to preserve information, records, live patient monitoring, X-rays, and more from patients. Computers assist in setting up laboratory tools, monitoring heart rate and blood pressure, etc. Besides, computers allow physicians to easily exchange patient data with other medical specialists.

Education- 

They help people get different educational materials (such as images, videos, e-books, etc.) in one place. Also, computers are best suited for online classes, online tutoring, online exams, and task and project creation. Also, they can be used to maintain and track student performance and other data.

Banking- 

Most countries use online banking systems so that customers can access their data directly. People can verify the balance of their account, transfer cash, and pay online bills, including credit cards. Besides, banks use computers to execute transactions and store client information, transaction records, etc.

Short Computer Essay in English

A computer's a programmable device that accepts raw data(input) and processes it as output with a group of instructions (a program) to supply the result. It renders output after performing mathematical and logical operations and can save the output for future use. The word "computer" derives from the word "computare" in Latin, which means calculating.

Types of Computer

Computers are of different types based on different criteria. Based on their size, computers are of five types:

Micro Computers- 

It is a single-user computer that has less capacity for speed and storage than the other types. For a CPU, it uses a microprocessor. Laptops, desktop computers, personal digital assistants (PDAs), tablets, and smartphones are common examples of microcomputers. Microcomputers are generally designed and built for general use, such as browsing, information search, the internet, MS Office, social media, etc.

Mini Computers- 

Minicomputers are also referred to as "Midrange Computers." They are multi-user computers designed to simultaneously support multiple users. Therefore, they are generally used by small companies and firms. 

Mainframe Computers- 

It is also a multi-user computer that large companies and government organizations use to run their business operations as large amounts of data can be stored and processed. Banks, universities, and insurance companies, for example, use mainframe computers to store data from their customers, students, and policyholders.

Super Computer- 

Among all types of computers, supercomputers are the fastest and most costly computers. They have an enormous capacity for storage and computing speeds and can therefore perform millions of instructions per second.

Workstations-  

It is a single-user computer with a comparatively more powerful microprocessor and a high-quality monitor compared to a mini-computer.

Essays About Computers: Top 5 Examples Plus Prompts

Computers are helpful technology that many of us use on a daily basis; if you are writing essays about computers, use our essay examples and prompts below. 

We often recognize computers as the devices we use to browse the internet, communicate with others, and type down notes, but there is more to a computer than this. A complex set of processes, calculations, and operations performs everything we do on a computer. Without a doubt, computers make our lives easier and enhance our personal and working life.

5 Top Essay Examples

1. types of computers by brent dawson, 2. uses of computers in education by kristina barroso, 3. our dependency on computers by nora fox, 4. neural networks: is your brain like a computer by shamli prakash.

• 5. ​​The Human Brain vs. Supercomputers… Which One Wins? By John Staughton

1. The Many Uses of Computers

2. can computers take over society, 3. is computer science a worthwhile program to study, 4. pros and cons of computers, 5. can computers compete with the human brain.

“Calculations for things such as automotive design, weather forecasting, and aerospace use supercomputers. Embedded computers are used for functions in a larger product. They are located in things such as automobiles, consumer electronics and office machines. As we all know computers come in many shapes and sizes. They can be used for many different things and can be located anywhere. Technology has increased so much that the most unheard compact thing can be a computer.

Dawson stresses that computers can come in all shapes and sizes. There are different types of computers, such as personal computers, mobile computers, game consoles, and supercomputers, each with its own functions and specialties. He briefly touches on each type of computer and its uses. Technology has come a long way, as the most complex computers are everywhere, whether in laboratories, offices, or even our mobile phones or watches. 

“Critics argue that spell check and other computer features that automatically correct errors in spelling and punctuation make students too lazy to learn and apply the rules themselves. These features, however, help point out where students went wrong and offer valuable learning opportunities that can help students enhance their understanding of appropriate spelling and punctuation.”

In her essay, Barroso discusses the advantages and disadvantages of incorporating computers into education. They allow schools to maximize online resources, foster student engagement, and make it easier for teachers and students to perform school-related tasks. However, they may make students lazy to check mistakes, thinking that the computers will automatically check them. Ultimately, the pros outweigh the cons. 

“As far as I concerned, computer is a great invention and it is useful to human life. It should be impossible to live without computer as we get too much used of computers nowadays. However, we should use it wisely. We know the fact that the more we rely on computer, the more we will lose in our life. So, we should also find ways to make our dependence on computers less dangerous to us, so that we will not rely on computer completely.”

Fox discusses the state of society today where we rely far too much on computers. They help us greatly in our daily lives, but they have made us depend on technology for information rather than thinking for ourselves. And if something goes wrong, like the servers crash, the world is at a standstill. Computers are a net good for society, but we must avoid revolving our lives around technology. 

“In data science terms, this phase is somewhat akin to ‘Model Training’ — the more things a child is exposed to the more the synapses associated with it get built. A good example is language — the more a child is exposed to linguistics in early years, the more evolved the area of her brain that is associated with languages would get. Ditto for other cognitive and non-cognitive abilities.”

Prakash discusses the different ways in which our brains operate as computers. An information processing system has five components: input, output, storage, processing, and program. The human brain does have all of these components, which are used to perform our daily functions. She looks into how human intelligence can be “trained,” like computers are developed. 

5. ​​ The Human Brain vs. Supercomputers… Which One Wins? By John Staughton

“When the brain identifies a more efficient or effective way to compute and function, it can morph and alter its physical and neuronal structure, hence the term “plasticity“. Until we achieve true Artificial Intelligence (in which computers should theoretically be able to re-wire themselves), neuroplasticity will always keep the human brain at least one step ahead of “static” supercomputers.”

Staughton writes about how much more advanced computers have become in recent decades, with some of them being able to outsmart humans in tasks such as chess. However, he explains that our brains are very different from technology and are inherently superior to even the most powerful computers in terms of efficiency, adaptability, and many other factors. However, he keeps the door on computers, eventually developing beyond our capabilities in the future.

Long Essay On Computer

As technology continues to evolve, computers have become a fundamental part of our daily lives. From helping us communicate with friends and family to managing our finances, computers are truly a lifestyle necessity. In this essay, we will explore the history of computer technology and its current applications in everyday life. By delving into the past and present of computers, we can better understand their impact on society and how they are shaping our future.

Introduction to Computer and Its Uses

Computers are becoming an increasingly common part of our everyday lives. They are used for a wide variety of tasks, including keeping track of our personal finances, communicating with friends and family, and even finding a new job. computers can perform all of these tasks much faster and more accurately than we could without their help.

Despite their usefulness, computers still remain somewhat mysterious to many people. How do they work? What do all those strange words mean? In this article, we will attempt to answer some of these questions by taking a look at the history of the computer and how it has evolved over time. We will also explore some of the different ways that people use computers in their everyday lives. By the end of this article, you should have a better understanding of what computers are and how they can be helpful in your life.

History of Computer Technology

The history of computer technology is often referred to as the history of information processing. This term was first used by John W. Mauchly in a paper presented at a conference in 1948. Mauchly and his co-author, J. Presper Eckert, built on the work of British mathematician Alan Turing and his concept of the Turing Machine. The Turing Machine was a theoretical device that could perform any mathematical calculation that could be carried out by hand.

Mauchly and Eckert’s computer, called ENIAC (Electronic Numerical Integrator And Computer), was far more than a simple calculator. It was the first machine that could store programs in memory and execute them at high speed. ENIAC was completed in 1945, just in time for the U.S. Army to use it during World War II to calculate artillery firing tables.

After the war, Eckert and Mauchly founded their own company, which soon introduced the UNIVAC (Universal Automatic Computer), the first commercial computer. In 1951, UNIVAC was used to predict the winner of the U.S. presidential election; it correctly predicted Dwight Eisenhower’s victory over Adlai Stevenson.

The history of computer technology is marked by a series of significant technological advances and milestones:

Types of Computers and Their Purposes

There are four main types of computers: desktop, laptop, tablet, and smartphone.

Desktop computers are the most common type of computer. They are designed for use at a desk or table. Desktop computers come in a variety of sizes, from small form-factor models to all-in-one models that incorporate the monitor into the same unit as the CPU.

Laptop computers are designed for portability. They are smaller and lighter than desktop computers, and they typically have longer battery life. Many laptops can be used as a tablet by folding back the screen, or they may have a separate touchscreen display that can be detached from the keyboard.

Tablet computers are designed for portability and touch input. They typically have a touchscreen display and lack a physical keyboard. Many tablets can connect to an external keyboard for additional productivity. Tablet computers typically have longer battery life than laptop computers.

Smartphone computers are the smallest type of computer. They are designed primarily for use with a finger or stylus input, and they typically have shorter battery life than other types of computer.

Advantages and Disadvantages of Using Computers

Computers have become an essential part of our everyday lives. They are used in businesses, hospitals, crime detection and even to fly planes. With so many uses, it is hard to imagine our lives without them. However, as with most things, there are advantages and disadvantages of using computers.

Advantages: 1. Speed and Accuracy Computers can process large amounts of data quickly and accurately. This is especially useful in fields such as medicine and science where large data sets need to be analysed. 2. Communication Computers have made communication much easier. We can now send emails, video call and instant message people from all over the world at the click of a button. 3. Storage Computers allow us to store large amounts of data securely. This is important for both individuals and businesses who need to keep track of their records. 4. Organised Information The way computer store information means that it is easy to retrieve and organise. This is useful for both research purposes and everyday life (such as finding a contact’s details in an address book). 5. Automation Many tasks that used to be done by hand or manually can now be done by computers automatically (such as booking tickets online or setting a alarm clock). This saves time and effort. 6 Creative Applications Computers also allow us to be creative in ways that were not possible before; we can now edit photos, create digital artworks and make music with a few clicks of the mouse.

Disadvantages: 1. Environmental Impact Computers consume large amounts of electricity which can be damaging to the environment. Products such as laptops and tablets are becoming more energy efficient, but there is still room for improvement. 2. Security Issues The internet has made it easier than ever to access information, but it has also opened up new security risks such as identity theft and viruses. It is important that users take precautions when using the internet (such as installing anti-virus software) to protect their data from malicious threats. 3. Cost The cost of buying and maintaining computers can be expensive, especially for businesses who need to buy multiple machines. Furthermore, repairs and upgrades can also add to the cost over time. 4 Social Isolation Spending too much time on computers can lead to social isolation, as people become less likely to interact with each other in person. This can have an adverse effect on people’s mental health. 5 Addiction There is a risk that some people may become addicted to using computers or playing online games which could lead them to neglect more important aspects of their lives such as work or family. 6 Privacy Issues The internet has made it easier for companies to collect and store data about their users, which can lead to privacy issues. It is important that users are aware of the terms and conditions of any website before signing up or entering personal information.

Impact and Limitations of Computer Technology

As with any new technology, there are both benefits and drawbacks to using computers. While they have revolutionized the way we live and work, they have also created new challenges that need to be addressed. Here are some of the key impact and limitations of computer technology:

1. Increased Productivity: Computers have drastically increased our productivity by automating tasks and allowing us to work faster and more efficiently.

2. Improved Communication: With email, instant messaging, and video conferencing, we can communicate with anyone in the world at any time. This has made collaboration and networking much easier.

3. Greater Access to Information: The internet is a vast repository of information that is available at our fingertips. With a few clicks, we can find out anything we want to know.

4. Enhanced Entertainment Options: We can now enjoy entertainment on our computers through streaming services, social media, and gaming platforms.

5. More Convenient Shopping: Online shopping has made it possible to buy anything we want without having to leave our homes.

1. addiction: Many people develop addictive behaviors towards computer usage, which can lead to problems in personal relationships, work performance, and mental health. 2. cybercrime: The anonymity afforded by the internet has emboldened criminals who engage in activities like identity theft, hacking, and online fraud. This puts everyone who uses the internet at risk of becoming a victim.

Different Applications of Computers in the World Today

Different applications of computers in the world today include:

-Word processing and spreadsheets for businesses and students -Graphics and design for artists, architects, and engineers -Web browsing and email for communication -Music and video production for entertainers -Database management for schools, libraries, and hospitals

In conclusion, computers have become an integral part of our lives. They have helped improve our quality of life in many ways, from educational and professional opportunities to entertainment and leisure activities. The importance of computers will continue to increase as technology advances and they become more accessible for everyone. Computers are already a fundamental tool that has advanced the way we communicate, learn, work and play – so it is essential that all of us understand the basics about this powerful piece of technology!

Essay on Computer in English

Dear students, in this post, you will read an essay on a computer. It is an opinion essay. A computer is an indispensable gadget in modern times. Read the complete essay on computer as follows:

A computer is a valuable tool. Many people use computers every day for many purposes. Think about ways that people use computers. Write an essay for your classmates explaining why you think a computer is a valuable tool.

Please enable JavaScript

I have grown up on a farm, but even in our rural area, I can see ways that technology is being integrated into all areas of life. Computers play a vital role in society, affecting us as much as TV, cars, and electricity. Computers are an important tool because they help us communicate more easily, increase our efficiency, and add convenience to our hectic lives.

To begin, computers have vastly improved daily communication. E-mail has revolutionized the way many people stay in touch. For example, by using e-mail I was able to send a photograph of me, playing football, to my grandmother living away from me. She was thrilled, and that evening she sent me an electronic greeting card with an interactive football game! Also, I can communicate instantly with other friends who are online. Also, my parents don’t get mad at me for tying up the phone to talk with my friends. On the computer, if you can type, you can chat.

Working on a computer helps me create professional-looking reports and letters. I am not a very neat person, so I depend on word processing to help make my work look neat. I can tell that my teachers like it when they don’t have to read my sloppy handwriting. Besides, writing a long essay or a report by hand is extremely tiring. Computers have been a real lifesaver in that department.

Another wonderful thing about computers is that they can help you get and stay organized. Many kids, adults, and organizations store a lot of information on the computer. I know that my parents keep their tax records on it. When tax time comes along, instead of having to sort through boxes of junk, they have everything they need at their fingertips because they stored it on the computer.

Finally, shopping on the Internet is another great benefit of having a computer. I’ve bought books, music CDs, and gifts on the Internet. It’s so much better than dragging myself around from store to store, lugging shopping bags, and waiting in long lines. Of course, my parents keep an eye on what I buy and how much it costs. They don’t let me shop on the Internet that much, but I love to do it when I can.

I think that computers are marvellous machines and that what they can do is only going to increase. I’ve described here only a few of the ways that computers make a huge difference to me, my family, and my friends right now. Just think about all the other ways computers help people and organizations around the world and about the other benefits they’ll bring in the future!

Witness testimony in Trump's hush money trial wraps for the day

From CNN's Kara Scannell, Lauren Del Valle, Jeremy Herb and Sabrina Souza in the courthouse

Witnesses walk through how bills were paid at Trump Org. Here’s what happened in court and why it matters

From CNN's Elise Hammond

In the hush money trial against the former president, prosecutors called two witnesses Monday who worked in accounting in the Trump Organization: Jeffrey McConney , a former Trump Org. controller, and Deborah Tarasoff , an accounts payable supervisor.

McConney walked the jury through the paper trail that showed how executives organized and paid back Michael Cohen for the money he sent to Stormy Daniels’ attorney. This is important because at the heart of the trial — the falsification of business records — are the payments to Cohen, which were listed as retainer fees.

Tarasoff described in more detail how checks were paid at the organization and when Trump’s approval was needed for payments.

Here’s what happened in court today:

Jeffrey McConney

• McConney testified that he had a conversation with Allen Weisselberg , former chief financial officer of the Trump Org., about a need to “reimburse” Cohen . McConney then showed jurors 12 checks, each for $35,000 , that were paid to Cohen in 2017. Cohen sent invoices for those checks and asked that the payments be listed as part of a “retainer agreement.” As previous testimony in the trial revealed, there was no actual retainer for Cohen.
• McConney also explained to the jury why Cohen was paid $420,000 in all and how each check was cut, first from Trump's revocable trust and then from his personal account .
• The jury also saw business records relating to the payment to Cohen that are tied to several of the 34 falsifying business records charges against Trump. The records show several rows and columns organized to record the payments.
• On cross-examination, Trump attorney Emil Bove questioned McConney about his knowledge of Trump's role in these payments. "President Trump did not ask you to do any of the things you described?" Bove asked. "He did not," McConney testified. He said he was told to do this work by Weisselberg. McConney also said he did not know if Cohen did legal work for Trump in 2017.

Deborah Tarasoff

• As accounts payable supervisor, Tarasoff said she would get an approved invoice , enter it into the system, cut the check and get it signed. Tarasoff testified that Trump or his sons needed to approve invoices of more than $10,000 and Trump was the only person who authorized checks from his personal account , including during his presidency.
• Tarasoff said Trump would sign the checks by hand. She said they were signed in black Sharpie . Tarasoff said Trump did not always sign the checks, even when Weisselberg approved them. He would “write 'void' and send it back,” she noted.
• Before Trump was president, Tarasoff testified that she “ would cut the check , put it with the backup and bring it over to Rhona (Graff) who would bring it in to Mr. Trump to sign,” referring to Trump’s former longtime assistant. The invoices and the checks were stapled together, she said, with the check on top of the invoice. When Trump became president, Tarasoff said they would mail checks to the White House .
• The jury was shown the voucher form that said "retainer" in the description line that Tarasoff said she obtained from the invoice. Tarasoff also confirmed each of the $35,000 checks with Trump’s signature were sent to Cohen.
• On cross-examination, she acknowledged that she was not present for conversations between Trump and Weisselberg about the payments. She also said she worked with Trump's children Eric, Don Jr. and Ivanka Trump, over the years. Tarasoff still works for Trump Org., which means she works for Eric Trump, who was also in the courtroom today.

What’s next: Prosecutor Joshua Steinglass estimated they still need about two weeks from tomorrow to make their case. He stresses that's a very rough estimate. The defense will also get an opportunity to call its witnesses after that if they choose.

Gag order hearing: Judge Juan Merchan  found Trump in contempt  for violating the gag order again, specifically concerning comments he made about the makeup of the jury in this case. Prosecutors had alleged Trump violated the gag order on four separate occasions . The judge ruled that the three other comments did not violate the order. "Going forward this court will have to consider a jail sanction," Merchan said, noting the $1,000 fine is not stopping him, but he told Trump “incarceration is truly a last resort .”

Remember: Trump faces 34 counts of falsifying business record s. Each criminal charge relates to a specific entry among the business records of the Trump Organization, according to the indictment . Prosecutors allege that Trump allegedly disguised the transaction to Daniels as a legal payment and falsified business records numerous times to “promote his candidacy” in the 2016 election.

Prosecutors roughly estimate they need about two more weeks to make their case

Judge Juan Merchan asks the prosecution how they're doing on timing for making their case.

Prosecutor Joshua Steinglass says they're doing "well," but estimates they still need about two weeks from tomorrow. He stresses that's a very rough estimate.

Trump tapped defense attorney Todd Blanche's arm as Steinglass made the estimation.

What Deborah Tarasoff said in just over an hour of testimony

From CNN's Kara Scannell, Lauren del Valle, Jeremy Herb and Sabrina Souza

Deborah Tarasoff, an employee in the Trump Organization’s accounting department, testified for just over an hour Monday about the check-writing process at the company.

Tarasoff helped arrange the 12 checks for $35,000, each signed by Donald Trump and sent to former attorney Michael Cohen in 2017 as reimbursement for the $130,000 hush money payment to Stormy Daniels.

She testified that after 2015 any invoice over $10,000 had to be approved by Trump or one of his sons. When she created the checks, Trump would sign them, she testified — or, if he disapproved, he would write “void” on them, she said.

"If he didn’t want to sign it, he didn’t sign it," she said. She knew he was the one signing them because, "It was signed in Sharpie and it was black and that’s what he uses."

She testified she had no decision-making authority but followed instructions, including getting invoices approved, entering them into the system, cutting the checks and getting them signed.

On cross-examination, she acknowledged that she was not present for conversations between Trump and former Trump Org. CFO Allen Weisselberg about the payments.

Judge tells jury they'll wrap up early today

"Jurors we're going to stop a little bit early today," Judge Juan Merchan tells the jury.

The jurors are now leaving.

Tarasoff is off the stand

Trump attorney Todd Blanche just wrapped up his cross-examination of Deborah Tarasoff.

There won't be a redirect, and Tarasoff is off the stand

Tarasoff says she doesn't know what happened to Cohen checks after they were mailed but they returned signed

Trump attorney Todd Blanche also noted that Deborah Tarasoff was not present for conversations between former Trump Org. CFO Allen Weisselberg and Donald Trump.

"When Mr. Weisselberg on some of the emails or Mr. McConney told you to go ahead and pay it, generate a check, you didn’t get permission from President Trump himself, correct?" Blanche said.

"Correct," she said.

She clarified with Blanche that all the checks to Michael Cohen shown in court were signed and that she doesn't know what happened with the checks after she mailed them to the White House.

But she did receive them back in the mail signed.

Blanche follows up with more questions about invoices

Attorney Todd Blanche is asking Deborah Tarasoff if Trump was focused on getting ready to be president during the start of 2017.

"I think so," Tarasoff replies.

Blanche follows up and asks whether the requests to pay for invoices "happens all the time?" Yes, Tarasoff says.

Blanche is trying to rehabilitate earlier testimony from Tarasoff that Trump would sometimes void checks for invoices he didn't want to pay. "If he didn’t want to sign it, he didn’t sign it," she testified earlier.

Tarasoff says Trump Org. is family-run and says she's worked with Don Jr., Eric and Ivanka Trump

Deborah Tarasoff confirms to defense attorney Todd Blanche that the Trump Organization is a family-run business. She says she has worked with Trump's children Eric, Don Jr. and Ivanka Trump over the years.

Trump is fully turned 90 degrees in his chair while Tarasoff is testifying. His arm is over the back of the chair, and he's facing toward Tarasoff.

Prosecutors have finished their questioning of Tarasoff

Prosecutors have wrapped up their questioning of Deborah Tarasoff. Trump attorney Todd Blanche is now starting his cross-examination for the defense.
