Ever since theadventof computers, there have been constant changes. First-generation computers of historicsignificance, such as UNIVAC, introduced in the early 1950s, werebasedonvacuum tubes. Second-generation computers,appearingin the early 1960s, were those in whichtransistorsreplaced vacuum tubes. In third-generation computers, dating from the 1960s,integratedcircuitsreplaced transistors. In fourth-generation computers such asmicrocomputers, which first appeared in the mid-1970s, large-scaleintegrationenabled thousands of circuitsto be incorporated on onechip.Fifth-generation computers are expected tocombinevery-large-scale integration with sophisticated approaches tocomputing, including artificial intelligence and true distributed processing.

We can define a computer as a device that accepts input, processes data, stores data, and produces output. According to themodeof processing, computers are either analog ordigital.They can be classified as mainframes, minicomputers, workstations, ormicrocomputers. All else (for example, the age of the machine) being equal, thiscategorizationprovides some indication of the computer’sspeed, size, cost, and abilities.
IV．Translate the following passage from English into Chinese.
A computer system includes a computer, peripheral（外围的）devices, and software. The electric, electronic, and mechanical devices used for processing data are referred to as hardware. In addition to the computer itself, the term “hardware” refers to components called peripheral devices that expand the computer’s input, output, and storage capabilities. Computer hardware in and of itself does not provide a particularly useful mind tool. To be useful, a computer requires a set of instructions, called software or a computer program, which tells the computer how to perform a particular task. Computers become even more effective when connected to other computers in a network so users can share information.
