First-generation computers of historic significance, such as UNIVAC, 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.A computer system includes a computer, peripheral(外围的)devices, and software.

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.计算机系统包括计算机、外围设备和软件。

The Fourth Generation of Computer (1971~now)
• The start of the fourth generation of computers was 1971. Large-Scale Integration circuits became basic computers. Our personal computers, or microcomputers, belong to this generation.

Generations of Electronic Computer
• The first generation of computer (1946 ~1958)
• The second generation of computer (1959~1964)
• The Third Generation of Computer (1964~1971) • The Fourth Generation of Computer (1971~now)

• The Analytical Engine
• Early Computers
• Electronic Computers
• Integrated Circuits
– Late in the 1960s the integrated circuit, or IC, was introduced, making it possible for many transistors to be fabricated on one silicon substrate, with interconnecting wires plated in place. The IC resulted in a further reduction in price, size, and failure rate. The microprocessor became a reality in the mid1970s with the introduction of the large-scale integrated (LSI) circuit and, later, the very large-scale integrated (VLSI) circuit (microchip), with many thousands of interconnected transistors etched into a single silicon substrate.

6.1 Basic Software Concepts
An additional and difficult-to-classify category of software is the utility, which is a small useful program with limited capability. Some utilities come with operating systems. Like application, utilities tend to be separately installable and capable of being used independently of the rest of the operating system. 另外一种难以分类的软件是实用软件，它是容量有限、但却 有用的小程序。一些实用程序捆绑在操作系统中。跟应用程 序一样，实用程序一般另外安装，并允许独立于操作系统使 用。

Software can be purchased or acquired as shareware (usually intended for sale after a trial period), liteware (shareware with some capability disable), freeware (free software but with copyright restrictions), public domain software (free with no restriction), and free software (software whose users agree not to limit its further distribution). 按购买或获取的途径，软件可以分为共享软件（通常在试验 期后打算销售），不具有部分性能的共享软件，免费软件 （免费但拷贝权受到限制），公共软件（不限制拷贝），和 用户同意不限制进一步分发销售的免费软件。

6.1 Basic Software Concepts
Software can be thought of as the variable part of a computer and hardware the invariable part. Software is often divided into application software (programs that do work users are directly interested in) and system software (which includes operating systems and many programs). The term middleware is sometimes used to describe programming that mediates between application and system software or between two different kinds of application software (for example, converting data from one file format to another file format). 软件可以看作是一个计算机中可变的部分，而硬件是不可变的部 分。软件通常可以划分为应用软件（用户直接感兴趣的程序）和 系统软件（包括操作系统和许多其它程序）。中间件有时用来指 处于应用程序和系统程序之间，或两种不同的应用软件之间的编 程（例如，实现将数据从一种文件ware Concepts
