In its more general usage, a personal computer (PC) is a microcomputer designed for use by one person at a time. Prior to the PC, computers were designed for (and only affordable by) companies who attached terminals for multiple users to a single large computer whose resources were shared among all users. The advent of the era of the personal computer was acknowledged by Time magazine in 1982, when they broke with tradition by choosing the PC as their "Man of the Year." By the late 1980s, technology advances made it feasible to build a small computer that an individual could own and use.
I realize that most places of business still rely on a PC, but many of them are also changing over to a tablet. One of the biggest reasons I keep my PC around is for the grand kids to play games on it. I don't have to worry about them breaking it because it is pretty old and not worth much anyway.
Internet and computer addiction plague a small percentage of computer users and mildly affect many other users. Severe Internet addiction may include addiction to cyber-relationships, online gaming, online gambling or adult content found on the Internet. People who suffer from Internet addiction feel anxiety when they are not online and may use the Internet to escape from depression, stress or loneliness in their everyday life. Though mild Internet use is healthy and normal, people who are addicted to the Internet feel as if they must constantly be on the Internet. This often leads to decreased work or school performance or losing touch with friends and family members.
Personal computers tend to be set up and left in one place, they are not intended to be mobile or carried around with you.

In recent years, the term PC has become more and more difficult to pin down. In general, though, it applies to any personal computer based on an Intel microprocessor, or on an Intel-compatible microprocessor. For nearly every other component, including the operating system, there are several options, all of which fall under the rubric of PC.
Personal computers, also known as PCs, are used occasionally by most people in America. Many people use the computer every day at home or work, and some spend the bulk of their day sitting in front of a computer. Though the computer makes it much easier to communicate, find information and create documents and slideshows, it sometimes leads to physical problems and decreased contact with friends and family.
I have a home office and prefer to use a PC over a laptop most of the time. They keep coming down in price and it doesn't cost much to have a really nice one these days. For some reason I just find it easier to navigate using a PC and like having a bigger monitor screen to look at. When using a laptop or tablet, I feel like there isn't enough space.
Modern PCs are very powerful and are now relatively inexpensive. You will find very similar machines both in the home and office environments.

Because of the Internet, most people are used to having information constantly at their fingertips. In just a few seconds, you can type a website URL into the search bar of your browser and visit a website full of information. There are online encyclopedias, books and user-submitted communities designed to provide specific types of information, such as video game walkthroughs. Offline, you can use digital encyclopedia software or play education games.

But one of the most significant of the inventions that paved the way for the PC revolution was the microprocessor. Before microprocessors were invented, computers needed a separate integrated-circuit chip for each one of their functions. (This was one reason the machines were still so large.) Microprocessors were the size of a thumbnail, and they could do things the integrated-circuit chips could not: They could run the computer’s programs, remember information and manage data all by themselves.
All PCs have several basic components that allow them to function and be used. The microprocessor controls everything the computer does, and every process has to go through it first. Computers also have memory, both long-term (read-only memory or ROM) and temporary (random-access memory or RAM), as well as data storage. ROM contains the basic software that allows the computer to boot up and generally does not change; RAM is used to store information that the computer is currently working with, such as open programs.
The role of the personal computer in the field of education is also prominent . In 2010, it is common among college and school students to have a personal computer at home, and some even bring laptops to school. Students can research papers and essays online, looking for both historical facts and the latest happenings around the globe. Most colleges and schools have personalized web pages to display important notices to students, and students find this to be a convenient way to get updates on campus events. Small children have access to websites for learning to read, learning math, science and many other subjects. Parents can even home-school their children through online curriculum.
