WEBVTT Kind: captions Language: en 00:00:17.029 --> 00:00:21.779 A desktop computer is made up of several basic parts, and in this video we're going to show 00:00:21.779 --> 00:00:25.869 you what these parts are, and what they're used for. 00:00:25.869 --> 00:00:30.769 The computer case contains the main components of the computer. This is where the actual 00:00:30.769 --> 00:00:36.149 processing happens. Today, most cases are tower cases, which means they stand up vertically. 00:00:36.149 --> 00:00:43.670 Sometimes you may see a horizontal case, which is often called a desktop case. 00:00:43.670 --> 00:00:47.850 In order to view anything on your computer, you'll need to have a monitor. The monitor 00:00:47.850 --> 00:00:54.850 connects to the video card inside your computer, to display images and text on the screen. 00:00:55.809 --> 00:01:01.530 Most monitors have LCD or LED displays, which can be made very thin, so they don't use much 00:01:01.530 --> 00:01:07.300 desk space. To save even more space, you can buy an all-in-one computer, which combines 00:01:07.300 --> 00:01:13.069 the monitor and the computer case into a single unit. 00:01:13.069 --> 00:01:18.179 To interact with your computer, you'll need a keyboard and mouse. Keyboards come in different 00:01:18.179 --> 00:01:25.179 shapes and sizes: for example, ergonomic and wireless keyboards. The mouse is used to control 00:01:25.439 --> 00:01:30.990 the mouse pointer on the screen. It can either be optical, which has an electronic eye on 00:01:30.990 --> 00:01:37.610 the bottom, or mechanical, which uses a rolling ball to detect movement. 00:01:37.610 --> 00:01:44.259 Some people prefer to use a trackball or touchpad instead of a mouse. These use less desk space, 00:01:44.259 --> 00:01:48.880 since they don't need to move when you're using them. 00:01:48.880 --> 00:01:53.609 So those are the basic parts of a desktop computer. As you can see, each part plays 00:01:53.609 --> 00:01:58.039 an important role, and you'll become very familiar with these parts as you gain more 00:01:58.039 --> 00:01:59.659 experience with your computer.
