A cluster is the smallest single unit of the space on a disk (a hard disk or a floppy or even an optical disc) that your computer's operating system keeps track of separately. The operating system keeps systematic records of which clusters are occupied by each file stored on the disk (in DOS, this is called the file allocation table, or FAT). Clusters usually consist of more than one sector, a sector being the smallest unit of disk space that the computer can read data from or write data on. There are too many sectors on a hard disk to keep track of them all individually, so the operating system deals with them in groups called clusters instead.

A microprocessor is a single chip that is the central processing unit, or the brains of a computer. To function as a complete computer, it also needs memory, a clock) and a power supply. Well, a computer on a chip has its own built-in clock and its own memory, so all it needs is a power supply to function. These tiny things are used in all kinds of things, from car parts to children's toys.

The Desktop is the background on your screen when you're using a Macintosh, Microsoft Windows, and similar graphical user interfaces. The idea is that this screen background is sort of like the top of your real desk, and your program windows are all lying on the desktop in a pile. Some programs may refer to their own "desktops." In this case, the desktop is what you see on the screen when the program is running but no document is open.

A card, or printed circuit board, also known as a board, is a piece of plastic with chips attached to it. Chips are the tiny little circuits that run the computer. You buy a card and stick it inside the computer box. You can get accelerator cards (boards) that make your computer run faster, video cards that give your computer more graphic capability, and clock cards and printer cards or whole computers on a card. They range in price depending on what they do, who makes them, and so on. For instance, an accelerator card can cost $300-$1500.
