Take a look at the front and back of your computer case, and count the number of buttons, sockets, and slots you see. Now look at your monitor and count any that appear there. You probably counted at least 20. Each computer is different, so the buttons, slots, and sockets will vary from computer to computer. However, there are certain features you can expect to find on most desktop computers. Being familiar with the names of each and how they are commonly used will help you later on when you connect a new printer, mouse, digital camera, or other device.
