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.
