Computers are here to stay, whether we like them or not. They are part of the juggernaut of the Industrial Revolution which began in England with textile making. This put many independent weavers out of jobs. I think the most important thing to recognize about computers and the other innovations that go with it is that it keeps changing the job market. It has been said that a person should expect to change jobs several times during his or her life. The only way for an intelligent person to cope with this frightening reality is to keep preparing for new developments. And the best way to do this is through "continuing education." You have to foresee what is going to happen in your particular field of interest and source of income and be prepared to adapt to the new conditions. The best way to do this is through education in school, because the teachers know what is coming better than almost anybody else. There are plenty of good jobs for people who are prepared to fill them. But people who just want to feel comfortable in their present jobs and spend their time at work watching television or playing video games may be in for a rude shock if and when their job is eliminated or taken over by a robot!

The advantages of computers are obvious and have been covered by the previous answers. I would like to discuss the disadvantages.

Computers have put millions of people out of work. For example, they have ravaged the book-selling business. Book stores are closing all across the country because it is so much more convenient to buy books online and so much easier to find the books you want. But in many cases it is possible to read books on the monitor or to print them. Computers have created jobs but not as many as they have displaced. They are only in their infancy, too. More and more shopping is being done online. Even the supermarkets are being affected. It looks as though the cities are going to be transformed in coming years, and many small towns are already being wiped out of existence.

Another disadvantage of personal computers is that they are addictive. Everywhere you go you see people staring into their laptops, and you may wonder, as I do, what they are...

Computers have a wide range of advantages, one of them being able to work effortlessly on a day to day basis. They have revolutionized communication and continue to do so especially with advent of artificial intelligence which is making computer usage even easier by allowing it to run a number of commands simultaneously.

Another advantage of computers is that they enable seamless flow of business activities internationally at lower costs through internet connectivity.

A disadvantage of computers is that they are rapidly changing both in software and hardware and a large population of the world is not able to keep up, making their older machines obsolete and cannot perform functions when needed.

People have become accustomed to using their computers that they no longer talk to each other physically which I believe creates a disadvantage on a social context.

The advantages of computers focuses on communication in many different forms such as writing an email to your boss or video chatting with relatives in a different state. Another advantage is being able to work from home if you have family. Computers help you search for an item just by typing in a few key words to find what you are looking for. Children who have learning disabilities can also learn by watching videos and being able to use their fingers to navigate. You can also pay your bills easily on the computer instead of going in person to the store.

The disadvantages of having a computer is not being able to have human interaction. People are becoming less social and more focused on what is on the computer screen. More people are losing their jobs due to technology advancements such as retail losing their customers to amazon. People are not paying attention as to what is around their environment and can be putting their life at risk such as being robbed. Another disadvantage is not being able to enjoy the simple activities such as going to the movies because it is being replaced by Netflix and Hulu.

Computers allow their users to access a seemingly infinite amount of information. Users can explore regions and interact with people from diverse backgrounds, a few examples of experiences limited to those who were economically privileged. Computers provide immediate feedback, and can help students perform tasks more efficiently. However, computers certainly come with several very serious drawbacks.

Users can develop an unhealthy addiction to computers and the immediate gratification they offer. Computers are fast. Patience dwindles. Attention spans shrink. Students often find themselves distracted the possibilities while attempting to complete important tasks. Parents worry their son or daughter may be exposed to inappropriate content.

While the benefits may outweigh the drawbacks, one must have awareness and use caution whenever he or she interfaces with any type of technology.

I grew up in a world that lacked computers. I majored in English Lit and prepared all of my papers on an electric typewriter, after doing my research in an actual library.

Now I love the access to information that computers offer, and I can’t imagine not having one.

I believe computers provide opportunities for everyone to learn, whether it’s a housewife looking for a particular recipe, a student doing research for a paper or a businessman looking for the correct terminology in writing a proposal.

Computers, however, may isolate people by being a substitute for human interaction. Children are spending far too much time on computers, and not for educational purposes. Adults spend hours on social media sites like Facebook, when they once called or met with friends to learn what was happening in their lives.

Perhaps moderation is the only real answer.

samir123 | Student

the advantages of the computer are more than we can calculate it in notes ,but we can illustrate some of it like:

in health it help physicians to diagnosis of daises and help in manufacture of treatments.

in industry it help in control and more specific in manufacture processes.

it make us as we gather if connect it by the internet.

the dis advantages of the computer likes it is cancel the privacy of the people,

may be danger if we use deep web and sometimes it wastes the time.

I am aware that I am addicted to computers. However, a computer has too many advantages that one can use. We all know that the computer has brought a new age to humankind; namely the network technology, the digital revolution on the computer, offers us a more comfortable life. For example, computer has the following advantages:

First, you can access as much information as possible around the world through the Internet. Enter only a keyword or an address, then you can search on the website. Then come the desired information. Yes, the Internet is like a universal dictionary!

Second, information is accessible to all at all times. We can search a lot on the net, what you need right now, without going out of the house. You can get certain things cheaper.

Third, computer connects people to people. For example, we can exchange information via e-mail or talk through some application creations such as Skype or Msn with friends at the same time, write or communicate through the Webcam. By the way, one only covers the costs of internet access.

After all, it is great to be able to store information in a digital fashion on the computer. Apart from the fact that you need a little paper work. You can correct the file at any time in the computer and arrange. You can also edit a statistical task or a table in the computer. What to look for is to make a backup copy. We cannot deny that computers make our everyday life easier. With a computer, you can do the job quickly. Without a computer, much is not possible at all. Most importantly, you should use computers well.

Of course, the computer also has disadvantages. We rely more and more on the computer as a calculator and Google and other "knowledge portals" as knowledge and thinking aids. The basic understanding of the German language suffers from the auto correction functions to check grammar and spelling in writing programs like Word. In the end, we will spend less and less time writing. Computer games cannot only be addictive. Proven to make children lethargic and at worst, depressed or aggressive. Therefore, we should avoid computer games, especially if they are violent games.

Let's face it. We are lost without computers. Having a computer is essential to our existence in many ways. This is because most aspects of our lives require the use of a computer. Computers have advantages as well as disadvantages. In other words, to deal with the many good things that come with using a computer, we have to also be aware that disadvantages exist.

Some advantages of using a computer are: having access to news minute by minute, utilizing computer programs and software for school/work, keeping in contact with loved ones via email or other applications, keeping track of expenses and bank account information, applying for jobs, researching topics for personal and/or professional use, viewing and editing photographs, and using a computer for social interaction.

Along with having advantages, there are many disadvantages to using computers. These disadvantages include: cyber-bullying through social media or e-mail, hacking or manipulating bank accounts or credit card information, plagiarizing work, and stealing other people's identity. Because we rely on computers so often, if a server or program malfunctions, it is difficult for us to complete the simplest of tasks.

user1296879 | Student

The advantages of computers can be something as simple as creating a text document for a class or organizing something on a spreadsheet.  They can also be far greater like connecting us to a global society.  We are able to reach out to people whether they be family, friends, or countless others we may share interests with.  Computers have allowed us to explore places many would otherwise be unable to see. Learn things that would have previously been impossible.  Meet people we never even knew existed.  Computers have increased the knowledge base of all peoples around the world.

With this great power come disadvantages as well.  Many people, particularly younger generations find themselves becoming increasingly dependent on technology. This dependence creates an inability to be self-dependent/self-reliant when technology is unavailable. Computers can automate many processes and remove the possibility of human errors, but at the same time they remove the human experience and personal touch that is the corner stone of customer service.

Computers have really become essential to modern life. Computers have opened doors for many who are disabled or have social anxiety enables them to make a income comfortably from their home. Also the internet has allowed to easily contact loved ones across the world or even meet new people. Just from a click of a button on Google you can learn just about anything even learning a new language by yourself. However the internet has also opened doors for the ignorant and people who take joy in torturing others. The internet for some has become the bane of their existence because they were humiliated someway or form.

What are the advantages and disadvantages of computers

There are countless advantages to computers provide an efficient    medium of communication and calculation. Computers calculate things that would take people hours to do in hours, in minutes. They also allow people to communicate with others and keep updated with the rest of the world, 

Some disadvantages that come with computers is the amount of time that is wasted on them and dangers that can come with the internet such as child porn and online predators .  

taangerine | Student

Computers are a great way to get additional information in a matter of seconds. Because of computers, we are able to communicate in various ways such as the FaceBook, Instagram, etc. We are also able to organize information in various of ways as well. Our options are limitless because of the internet. 

However, computers can transmit information to practically anyone. It is unsafe esp. for those who have personal information on their computer. Furthermore, computers have decreased one's productivity throughout the day as well. Instead of exercising or doing work, one is playing on the computer instead.

The advantages of computers is we can access information ten times faster then we even could back in the days. Beforehand others have to sift through the books looking and trying to find the information yet today we can type it into Google and find the answer in a second. The disadvantage is that too many people use computers too often and even young kids start off with a computer which leads to too much time on the internet that can damage eyes. And although we can get answers within a second, we cannot retain it.

Pros: faster communication, Greater accessibility, freater range of informatiom to be accessed, generally it is covered under these big groups. Information tracking is also much easier

Cons: addiction to games, Greater access to drugs, explicit materials

acompanioninthetardis | Student

The advantage of computers is that they allow information to be easily accessed and stored, whereas the disadvantage of computers is what people can choose to do with this information. also another disadvantage is that computers and modern technology turn addicting for some people and eventually the face to face conversations, and contact with the outer world lessens. Another advantage may be that it introduces to us a world of infinite possibilities, computers encourage us to imagine new things, teach us new ways etc..

Computers are changing the face of the world. the ability to gain access to information regardless of where one is , has got to be one of the biggest advantages. We can learn so much more infomation in a quicker period of time

However computers also help take away some of the ingenuities of man. People can easily use a computer to figure out a math problem, find an essay or learn how to build a bomb. Nothing is original anymore , nothing is safe.

The Computer

The computer is a very popular technological invention. It was invented in the mid-twentieth century. It has very quickly ascended to the top of people’s list as to what they need to survive the day. The computer is a very famous and [sometimes, usually] helpful invention to all. It is used by millions of people around the world, for different purposes. There are some positive points to its uses, but also some negative points. In this essay, I will talk about the negative points. The three negative points of using a computer are: it may harm your eyes, it can take time away when you can be doing more beneficial things, and too much information written on it about yourself can be dangerous. 
Long hours at a computer can harm your eyes, say experts. They advise frequent short breaks every half hour or so to minimize the damage. Studies have shown that eyestrain and other vision problems can be found in as much as nine out of ten people using computers often, say Kerry Beebe, an optometrist and spokesman for the American Optometric Association. The most common symptoms are eyestrain, blurred vision, double vision, excessive tears, dry eyes and excessive blinking or squinting. Visual problems can also result in physical problems such as headaches and neck or shoulder pain, reported Health Central. So this means you must never use a computer non-stop without taking any breaks – you should always take breaks to reduce the risk of any of these eye and body problems. 
The computer may waste a lot of time for you – you are capable of using your time way more wisely. It wastes time because there are many things on it that distract you when you’re trying to do something, like pop-up ads. You’re trying to get somewhere, and then one of them comes up and maybe tempts you to click on it. This is an example of wasting your time on the computer. Little things like this can make you even lazier to finish the work that you actually had to do, so you don’t really get across completing it. Then again, you choose if you want these things to affect you. If you actually wanted to finish what you had to do, you wouldn’t have let these things influence you.

The last negative thing about computers is that if you put out too much information about yourself, it might be very dangerous. There are many people who say they’re somebody that they’re not, and anybody that is not too careful can easily be tricked into believing them. Internet stalkers have killed at least four teenagers in the past three years, and law enforcement authorities count about 5,000 reports of attempted sexual predation over the Internet in the past year, according to Parry Aftab, who is the executive director of “,” which is an Internet safety organization. According to this information, you could easily become one of those victims. This is why you must take caution when using the computer.

With the advent of technology, computers can now make many well-informed decisions that managers or office workers may deem unnecessary for a human to make. These decisions may include crunching profit numbers to determine future layoffs or gauging whether certain global offices should remain open or not. If you are evaluating whether computerized decision making is right for your organization, there are advantages and disadvantages to implementing the technology into your corporate strategy. While human brains can contain a high level of information to use in making a decision, a computer's "brain" can contain even more data and information, depending on the storage space it is connected to. With a higher capacity for more data, especially data that a human brain might not retain, such as complex equations, more information can be incorporated into the "brain" or algorithm of the computer in its decision making, leading to better results. 

Computers can process information much faster than a human brain. One advantage to computers making decisions is that you will have decisions made faster and more accurately than a human brain, which may get hung up with different factors involving the decision, leading to slower overall results. Also, unlike people who can become tired or suffer from a lack of concentration and deliver inaccurate decisions, a well-tuned computer is always alert and can process reams of information without growing bored or tired, leading to more precise results.The high cost of purchasing the right computer equipment, including a high amount of computer memory and store, is one disadvantage to computer technology in decision making. Also, the cost of a computer professional to write the algorithm you'll need for your type of decision can come at a high price. By the time your equipment is purchased and your algorithm is written, it may also already be obsolete since technology is constantly advancing and building on what already works to make it better

There are many advantages of having a computer, however there are some disadvantages, take it from a computer teacher.

One advantage is using a computer to write you papers, letters, notes and anything esle you  can think of. IF this was before computers you would need to write each one by hand and if you made a mistake you would have to start all over. By using a computer to do this it save you time and energy. If you have changed you mind about something you can easily go on the computer delete it and write what you would like.

Another advange with in that is spelling and grammer, its not perfect but it does help having spell check and grammer check there for you.  If points out most items not everything but its better than nothing.

Another thing is why it is great is that you are able to communicate with other people who do the same thing as you or need help on the same topic where you would not be able to do this if wqe didnt have the internet.

However a disatvanage is that students do not know how to write essays or research papers, because they feel it is okay to just copy. That does become to be a problem becasue they always want to copy and paste information to make their life easier, however using the internet for research has already made things easier for them yet they dont see that becasue its what they are used too.

Another problem could be virus. Or even when the computer breaks people have no idea what to do with out it.  This how people are overly dependted on it.

Advantages of computers:

  • Increases speed of computing and processing information in any other way.
  • People can use sophisticated statistical and mathematical tools for decision making and further purposes without learning in details the algorithms used for computing. This way people can use much more sophisticated analytical tools that would have been possible with only manual information processing.
  • Computers can store large volumes of information without occupying too much space, as is in the case of information stored in form of books and paper documents.
  • Computer processing eliminates the human errors of computing and information processing.
  • Information once entered in computer system can be easily accessed by the same person or other persons at different times for different persons. This reduces the work load of capturing same information multiple times for different purposes. It also makes it possible for different person to work with same information, avoiding the possibility of different persons using different versions of the same information.
  • The work of entering and editing information is made mush more easy and simple by software that offer many powerful user friendly features for performing these tasks.
  • Computer now offer sophisticated and powerful software for representing information in rich formats with visual and video facilities.
  • Computers combined with communication technology offer very fast speed and rich communication facility at low cost.
  • Computers, with all these features are now used for automating all kinds of equipments and processes.

Disadvantage of Computers

  • The cost of computer and associated equipments is falling steadily. Still these equipments are and continue to be much more costly as compared to manual processing equipments like pen and pencil. Also technological complexity of these equipment makes it more difficult to learn and maintain these equipments as compared to equipments of manual information processing.
  • Use of computers require additional infrastructure, such as power supply and software back up. This increases the chances of problems due to failure of infrastructure. For example, a computer will not work where there is no electric power supply. Even a laptop with a battery will work without power supply only for a limited period.
  • Failures of computer system can be more serious and difficult to correct. For example, one scratch on a hard disk can make the complete data on the disk inaccessible. In comparison, manual system faults have comparatively limited impact. One page torn from a cabinet full of documents has no impact on other documents.
  • Computers generally reduces the errors of processing. However if there is an error in input data, it can result in major blunders in the processing which the computer system is unable to detect. In manual systems the chances of such blunders passing undetected and corrected is much less.
