According to the mode of processing, computers are either analog or digital.They can also be classified as mainframes, minicomputers, workstations, or microcomputers.All else (for example, the age of the machine) being equal, this categorization provides some indication of the compu ter’s speed, size, cost, and abilities.Ever since the advent of computers, there have been constant changes. First-generation computers of historic significance, such as UNIVAC(通用自动计算机), introduced in the early 1950s, were based on vacuum tubes. Second-generation computers, appearing in the early 1960s, were those in which transistors replaced vacuum tubes. In third-generation computers, dating from the 1960s, integrated circuits replaced transistors. In fourth-generation computers such as microcomputers, which first appeared in the mid-1970s, large-scale integration enabled thousands of circuits to be incorporated on one chip. Fifth-generation computers are expected to combine very-large-scale integration with sophisticated approaches to computing, including artificial intelligence and true distributed processing.IV. Translate the following passage from English into Chinese:计算机将变得更加先进，也将变得更加容易使用。

Text A The function of computers
1. Central processing unit and Microprocessor
A general purpose computer has four main components(1): the arithmetic logic unit (ALU), the control unit, the memory, and the input and output devices (collectively termed I/O). These parts are interconnected by(2) buses, often made of (3) groups of wires.

Text A The function of computers
• Inside each of these parts are trillions of small electrical circuits(4) which can be turned off or on by means of an electronic switch. Each circuit represents a bit (binary digit) of information so that when the circuit is on it represents a "1", and when off it represents a "0" (in positive logic representation). 注1 The circuits are arranged in logic gates so that one or more of the circuits may control the state of one or more of the other circuits.

1.1 The Invention of the Computer
1.1.1 The ENIAC
Before the EDVAC was finished, several other machines were built that incorporated elements of the EDVAC design of Eckert, Mauchly, and von Neuman. One was the Electronic Delay Storage Automatic Computer, or EDSAC, which was developed in Cambridge, England. It first operated in May of 1949 and is probably the world’s first electronic stored-program, general-purpose computer to become operational. The first computer to operate in the United States was the Binary Automatic Computer, or BINAC, which became operational in August of 1949. 在 EDVAC 完 成 之 前 ， 其 他 一 些 机 器 建 成 了 ， 它 们 吸 收 了 Eckert 、 Mauchly和Neuman设计的要素。其中一部是在英国剑桥研制的电子延迟 存储自动计算机,或简称EDSAC，它在1949年5月首次运行，它可能是世 界的第一台电子储存程序、通用型计算机投入运行。在美国运行的第一 部计算机是二进制自动计算机,或简称BINAC,它在1949年8月投入运行。

Software: A program consists of the step-by-step instructions that tell the computer how to do its work. Software is another name for a program or programs. The purpose of software is to convert data (unprocessed facts) into information (processed facts). For example, a payroll program would instruct the computer to take the number of hours you worked in a week (data) and multiply it by your pay rate(data) to determine how much you are paid for the week (information).

When you think of a microcomputer, perhaps you think of just the equipment itself. That is, you think of the monitor or the keyboard. Yet, there is more to it than that. The way to think about a microcomputer is as part of an information system. An information system has five parts: people, procedures, software, hardware, and data.
