Computer Basics: Basic Parts of a Desktop Computer

A desktop computer is made up of several basic parts, and in this video we're going to show

you what these parts are, and what they're used for.

The computer case contains the main components of the computer. This is where the actual

processing happens. Today, most cases are tower cases, which means they stand up vertically.

Sometimes you may see a horizontal case, which is often called a desktop case.

In order to view anything on your computer, you'll need to have a monitor. The monitor

connects to the video card inside your computer, to display images and text on the screen.

Most monitors have LCD or LED displays, which can be made very thin, so they don't use much

desk space. To save even more space, you can buy an all-in-one computer, which combines

the monitor and the computer case into a single unit.

To interact with your computer, you'll need a keyboard and mouse. Keyboards come in different

shapes and sizes: for example, ergonomic and wireless keyboards. The mouse is used to control

the mouse pointer on the screen. It can either be optical, which has an electronic eye on

the bottom, or mechanical, which uses a rolling ball to detect movement.

Some people prefer to use a trackball or touchpad instead of a mouse. These use less desk space,

since they don't need to move when you're using them.

So those are the basic parts of a desktop computer. As you can see, each part plays

an important role, and you'll become very familiar with these parts as you gain more

experience with your computer.
