插图:The basic job of computer is the processing of information. For this reason, computers can efined as devices which accept information in the form of instructions called a program and haracters called data, perform mathematical and/or logical operations on the information, and hen supply results of these operation. The program, which tells the computers what to do and the ata, which provide the information needed to solve the problem, is kept inside the computer in a lace called memory.Computers are thought to have many remarkable powers. However, most computers, whether arge or small, have three basic capabilities.First, computers have circuits for performing arithmetic operations, such as addition, ubtraction, division, multiplication and exponentiation.Second, computers have a means of communicating with the user. After all, if we couldn't feed information in and get results back, these machines would not be of much use.Third, computers have circuits which can make decisions. The kinds of decisions which computer circuits can make are of the type: Is one number less than another? Are two numbers equal? And, is one number greater than another?A CPU can be a single microprocessor chip, a set of chips, or a box of boards of transistors, chips, wires, and connectors. Differences in CPUs distinguish mainframes, mini- and microcomputers. A processor is composed of two functional units: a control unit and an arithmetic/logic unit, and a set of special workspaces called registers.The control unit is the functional unit that is responsible for supervising the operation of the entire computer system. In some ways, it is analogous to a telephone switchboard with intelligence because it makes the connections between various functional units of the computer system and calls into operation each unit that is required by the program currently in operation. The control unit fetches instructions from memory and determines their type or decodes them. It then break each instruction into a series of simple small steps or actions. By doing this, it controls the step-by-step operation of the entire computer system.
