Most computers are meant to be used by only one person at a
time. Such computers are often shared by several people (such
as those in your school's computer lab), but only one user can
work with the machine at any given moment.
The six primary types of computers in this category are
» Desktop computers
» Notebook computers
» Tablet computers
» Handheld computers
» Smart phones
These systems are all examples of personal computers (PCs)—
a term that refers to any computer system that is designed for use by a single person. Personal computers arc also called microcomputer, because they are among
the smallest computers created for people to
use. Note, however, that the term personal
computer or PC is most often used to describe
desktop computers, which you w ill learn about
in the following section.
Although personal computers are used by
individuals, they also can be connected together to create networks . In
fact, networking has become one of the most
important jobs of personal computers, and
even tiny handheld computers can now be connected to networks.
