23、 computers and digital computers. Unless you are a scientist, you probably will not use analog computers. These computers are important because they are able to measure quantities such as electricity and temperature. In contrast, digital computers perform their tasks by counting. Some digital comput

24、ers are built to help solve only a specific kind of problem. For example, digital computers that monitor airplanes flying in and out of airports are built only for that task. Most digital computers, though, can be used to help solve many kinds of problems. Among them, microcomputers and minicomputer

25、s are two kinds of common digital computers. Microcomputers, also called personal computers, are the newest computers. Many are about the size of a very small television set.

Like microcomputers, minicomputers are used in small businesses

28、. However, they are larger than microcomputers and are used more frequently in large offices and businesses than in small businesses. Another difference is that more than one person can use a minicomputer at the same time. We call this time-sharing. Some minicomputers can have more than a hundred pe

29、ople time-sharing them. Each person who uses a minicomputer has a computer terminal that is connected to the minicomputer by interface wires. But even though more than one person can use a minicomputer, the computer has only one CPU. With the help of the operating system, the CPU is able to divide i

32、he whole thing, believe me.2) You know something; I thought youd be different.
