Algorithms 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.

四、翻译句子

1. 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.

They are more powerful and reliable and, importantly, are very economical in terms of energy consumption. Their presence opens a new era in the field of IT technologies and means that the cloud technology is getting closer. These processors are primarily designed for servers, data centers (DPC) and supercomputers. The emergence of this class of devices is not accidental. According to the regional director of Intel in Russia and other CIS states Dmitri Konash who spoke at the event, the market of IT-technology is developing so rapidly that, according to forecasts, by 2015 there will be 15 billion devices connected to the Internet, and over 3 billion of active users. 上周，英特尔公司向俄罗斯和其它独联体国家的公众推出了英特尔Xeon E5-2600系列处理器，它们更加强大可靠，尤其是在能量消耗方面更加经济实惠。它们的问世意味着IT技术领域开始了一个新时代，标志着云技术距离我们越来越近。 这些处理器主要是为服务器、数字处理中心和超级计算机设计的。这种处理器的出现并非偶然。根据英特尔公司俄罗斯和其他独联体地区负责人Dmitri Konash就此事发表的看法，IT技术市场的发展速度极快，根据预测，到2015年与英特网连接的设施将有150亿，用户超过30亿。 [Ex 6] 1.
