Personal
Computer (PC), computer in the form of a desktop or laptop
device designed for use by a single person. PCs function using a display
monitor and a keyboard. Since their introduction in
the 1980s, PCs have become powerful and extremely versatile tools that have
revolutionized how people work, learn, communicate, and find entertainment. Many
households in the United States now have PCs, thanks to affordable prices and
software that has made PCs easy to use without special computer
expertise. Personal computers are also a crucial component of information
technology (IT) and play a key role in modern economies worldwide.
The usefulness and capabilities of personal computers can be greatly enhanced by connection to the Internet and World Wide Web, as well as to smaller networks that link to local computers or databases. Personal computers can also be used to access content stored on compact discs (CDs) or digital versatile discs (DVDs), and to transfer files to personal media devices and video players.
Personal computers are sometimes called
microcomputers or micros. Powerful PCs designed for professional or
technical use are known as work stations. Other names that reflect different
roles for PCs include home computers and small-business computers. The PC is
generally larger and more powerful than handheld computers, including
personal digital assistants (PDAs) and gaming devices.
