Basic Computer Hardware Components
1 Keyboard
The keyboard is easy. We all know what a keyboard is, right? It’s the thing that look like part of a typewriter. Uh, oh, maybe you’re never seen a typewriter? OK, it looks like a cellular phone, except it’s bigger and has more buttons. Seriously, the keyboard is the part with the letters and numbers, where you put your hands and type. On most traditional computers, it is a separate device, connected by a cord, but it maybe attached to or built into one of the other parts, particularly in laptop computer.
2 Monitor
The monitor is the part that looks a lot like a TV set. You look at it and see pictures and words. When you type things on the keyboard, the letters and numbers show up on the monitor, or at least you hope they will. The monitor is also called the Display Monitor, or just the Display, or sometimes the Video Display, or maybe just the Screen. The important thing to know about the monitor is that it is not really the computer, it’s just the part that makes pictures for you to see. It is pretty common for technical support people to find out, after about half an hour on the phone, that the ordinary human being is turning the monitor on and off instead of the computer, and that’s why none of their instrucions have had any effect. Don’t let that happen to you.
3 Computer or CPU Box
The CPU Box is the part that, well, looks like a box. CPU Box is not really a good name for it, but it will have to do until somebody comes up with a name everybody can agree on. CPU stands for Central Processing Unit, and technical people refer to the box part as the CPU Box because that’s where the CPU is, and that’s where the real work gets done. Because that’s where the computing is really done, the CPU component alone can be called the computer. You might hear people says, “not the screen, but the actual computer” when referring to the CPU Box. Some people refer to it as the hard drive, since the hard drive is in there too, but that is confusing. The hard drive is inside the CPU Box alright, but you’ll drive technical people bonkers if you call the box a hard drive, because they just don’t think that way. Of course it’s nt logical to say that CPU is an OK name but hard drive isn’t, but remember that technical people aren’t normal and humor them. A box is a box, but not if it’s a CPU Box.
CPU Box come in two special types, called Desktop and Tower. The Desktop kind is designed to lie down flat, even though you can stand it on its side if you want to. In a desktop CPU Box, you will normally find that the openings for CD and Floppy disk drives are horizontal of their desk any more, but the name has persisted.

妈的，老子不打了。。把电脑机箱翻译成 CPU Box 还好意思写教材？！ go to hell.
