The Internet, then known as ARPANET, wasbrought online in 1969, which initiallyconnected four major computers at universitiesin the southwestern US . The early Internet wasused by computer experts , engineers, scientists, and librarians. There was nothing friendly about it. There were no home or office personalcomputers in those days, and anyone who used it, whether a computer professional or an engineeror scientist or librarian, had to learn to use a very complex system.The Internet matured in the 1970's as a result of the TCP/IP architecture. As the commands for E-mail, FTP , and telnet were standardized, it became a lot easier for non-technical people to learn to use the nets. It was not easy by today' s standards by any means, but it did open up use of the Internet to many more people in universities in particular. Other departments besides the libraries, computer, physics, and engineering departments found ways to make good use of the nets -- to communicate with colleagues around the world and to share files and resources.In 1991, the first really friendly interface to the Internet was developed at the University of Minnesota. The University wanted to develop a simple menu system to access files and information on campus through their local network.Since the Internet was initially funded by the government, it was originally limited to research, education, and government uses. Commercial uses were prohibited unless they directly served the goals of research and education. This policy continued until the early 1990's, when independent commercial networks began to grow.(四) Choose the best answer according to Passage C.（根据上文的内容选择正确的答案。

Digital computer, also called electronic computer or computer, is a digital system that 3 various computational tasks. Digital computers use the 4 number system, which has two digits: 0 and 1.By using various coding 5 , groups of bits can be made to represent not only binary numbers 6 other discrete symbols, such as decimal digits or letters of the alphabet. A computer system consists of hardware system and software system. Programs tell the hardware what to do. 7 software is designed to accomplish real-world tasks in fields such as accounting, entertainment, and engineering. Computers are usually 8 into four broad categories: microcomputers, minicomputers, mainframe computers, and supercomputers.

The hardware of the computer is usually divided into three major parts or three 2 subsystems: the CPU, the memory subsystem, and the I/O 3 . The CPU is made up of three major parts, Register Set, the 4 logic unit, or ALU, and Control Unit. It performs many operations and controls computer. Memory is also known as 5 memory or main memory, which is cataloged into two major types of memory: Random Access Memory (RAM) and Read Only Memory (ROM).It refers to the 6 in the computer that hold whatever programs and data are available 7 immediate use by the CPU, along with the program’s data. Computer systems include special hardware 8 between the CPU and peripherals to supervise and synchronize allinput and output transfers. These components are called 9 units because they interface between the processor bus and the peripheral device. The I/O subsystem allows the CPU to 10 with input and output devices.1.

B 10.D Unit 4Algorithms are essential to the way computers process information, because a computer program is 1 an algorithm that tells the computer what specific 2 to perform in certain order in order to carry out a speci fied task, such as calculating employees’ paychecks or printing students’ report cards. Thus, an algorithm can be considered to be 3 sequence of operations that can be performed by a turning-complete system. In fact, a data structure is a way of 4 data in a computer so that it can be used efficiently. Often a carefully 5 data structure will allow the 6 efficient algorithm to be used. The choice of the data structure often begins from the choice of an 7 data type.A well-designed data structure allows a variety of critical operations to be performed, using as few resources, both execution time and memory space, as possible. Data structures are implemented by a 8 language as data types and the references and operations they provide. Moreover, different kinds of data structures are 9 to different kinds of applications, and some are highly specialized to certain tasks. For example, B-trees are particularly well-suited for implementation of databases, 10 networks of machines rely on routing tables to function.1. A. essentially B. essential C. partially D. mainly2.

Software refers to the programs that are 2 for the computer. It is possible to be familiar with various3 of computer software without being concerned with details of how the computer hardware operates.A programming language is a language used to write computer programs, which involve a computer 4 some kind of computation or algorithm and possibly control over 5 devices such as printers, robots, and so on. Programming languages differ from 6 languages in that natural languages are only used for interaction between people, while programming languages also allow humans to communicate 7 to machines. Some programming languages are used by one device 8 control another. A prominent 9 of programming languages is to provide instructions to a computer.

By using various coding techniques, groups of bits can be made to represent not only binary numbers but also other discrete symbols.2. System software includes not only the complex programs used by technicians to create application software in the first place but also the organizational programs needed to start up the computer and govern its use of other programs.3. Data are numbers and other binary-code information that are operated on to achieve required computational results.4. Rather than arithmetically or logically manipulating characters, a computer may concatenate strings of characters, replace some characters with others, or otherwise manipulate character strings.5. Software applications like word processing, electronic spreadsheets, database management programs, painting and drawing programs, desktop publishing, and so forth became commercially available, giving more people reasons to use a computer.1. By asserting these internal and external control signals in the proper sequence, the control unit causes the CPU and the rest of the computer to perform the operation needed to correctly process instructions.2. In a computer with virtual memory, less-used parts of programs are shifted from RAM to a hard disk and are moved back only when needed.3. A technique used to compensate for the mismatch in operating speeds is to employ an extremely fast, small cache between the CPU and main memory whose access time is close to processor logic clock cycle time.4. The data transfer rate of peripherals is usually slower than the transfer rate of the CPU, and consequently, a synchronization mechanism may be needed.5. In some computers the interrupt vector is an address that points to a location in memory where the beginning address of the I/O service routine is stored.1. The purpose of parallel processing is to speed up the computer processing capability and increase its throughput, that is, the amount of processing that can be accomplished during a given interval of time.2. It is characteristic of pipelines that several computations can be in process in distinct segments at the same time.3. To achieve the required level of high performance it is necessary to utilize the fastest and most reliable hardware and apply innovative procedures from vector and parallel processing techniques.4. In general, the greater the number of instructions in an instruction set, the larger the propagation delay is within the CPU.5. Although CISC processors are more complex, this complexity does not necessarily increase development costs.1. In short, communication problems arise when the language used for an algorithm's representation is not precisely defined or when information is not given in adequate detail.2. Another common algorithmic structure involves that the need to continue executing a statement or sequence of statements as long as some condition remains true.3. In many algorithms, running time will vary not only for inputs of different sizes, but also for different inputs of the same size.4. Thus, dynamic programming is a bottom-up technique that usually begins by solving the smallest subproblems, saving these results, and then reusing them to solve larger and larger subproblems until the solution to the original problem is obtained.5. The conversion from this conceptual one-dimensional array organization to the actual arrangement within the machine’s memory is straight forward and the data can be stored in a seguence of 24 memory cells with consecutive address in the same order envisioned by the programma.1. Documentation is needed for everyone who will be involved with the program——users, operators, and programmers.2. Rather, programs written in a high-level language or assembly language are converted to machine language, which is then executed by the computer.3. The corresponding programs set forth precise procedures, or series of instructions, and the programmer has to follow a proper order of actions to solve a problem.4. 4GLs may not entirely replace third-generation languages because they are usually focused on specific tasks and hence offer fewer options.5. Inheritance is the means by which objects of a class can access member variables and functions contained in a previously defined class, without having to restate those defi nitions.。

A secondary goal is to use the computer hardware in an efficient manner. An operating system is similar to a government. Its hardware, software, and data provide the basic resource of a computer system. The operating system provides the means for the proper use of these resources in the operation of the computer system. Like government, the operating system performs no useful function by itself. It simply provides an environment within which other programs can do useful work.四、问答题（30分，每题10分）1．What is a Processor? Describe components of the Processor.2.
