Desktop Computers
Many people use desktop computers at work, home,
school, or the library. They can be small, medium, or large in style,
and they usually sit on a desk. Once you add a monitor, mouse, and
keyboard, you have what is typically known as a desktop computer.
Most desktop computers are easy to upgrade and expand or add new parts. Another benefit of desktop computers is their cost. If you compare a desktop and laptop with the same features, you will most likely find that the desktop is less expensive.

Laptop Computers
The second type of computer you may be familiar with is a laptop computer, or a laptop. Laptops are battery- or AC-powered personal computers that are more portable than desktop computers, allowing you to use them almost anywhere.Tablet Computers
Tablet computers—or tablets—are handheld computers that are even more portable than laptops. Instead of a keyboard or touchpad, tablets use a touch-sensitive screen for typing and navigation. The iPad is an example of a tablet.
Servers
A server is a computer that serves up information to other computers on a network. Many businesses have file servers employees can use to store and share files. A server can look like a regular desktop computer, or it can be much larger
PCs and Macs
Personal computers come in two main styles: PC and Mac. Both are fully functional, but they have a different look and feel, and many people prefer one or the other
- PC: This type of computer began with the original IBM PC that was introduced in 1981. Other companies began creating similar computers, which were called IBM PC Compatible (often shortened to PC). Today, this is the most common type of personal computer, and it typically includes the Microsoft Windows operating system.
- Mac: The Macintosh computer was introduced in 1984, and it was the first widely sold personal computer with a graphical user interface, or GUI (pronounced gooey). All Macs are made by one company, Apple Inc., and they almost always use the Mac OS X operating system.
