III.Fill in each of the blanks with one of the words given in the following

list, making changes if necessary:

We can define a computer as a device that accepts input, processes data, stores data, and produces output. According to the mode of processing,

computers are either analog or digital. They can 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

computer’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 UNIV AC,

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.

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.

一、判断对错 1. The software system is the physical equipment that you can see and touch. 2. Typically, a data value is set to zero to represent FALSE and 1 value for TRUE. 3. In the earliest general-purpose computer, most input and output media were magnetic disks. 4. Supercomputers are largest, fastest, and most expensive computer available. 5. A computer system consists of hardware system and software system. 1. The data bus always receives data from the CPU, and the CPU never reads the data bus. 2. Main memory holds whatever programs and data are available for immediate use by the CPU. 3. Dynamic RAM does not have to be refreshed. 4.Dot-matrix printer work by squirting tiny droplets of liquid ink at the paper. 5. The auxiliary memory is very small, relatively expensive, and has very high access speed. 1. Shift registers operate in serial fashion all the bits of the word at a time. 2. RISC processors have larger instruction sets that often include some particularly complex instructions. 3. SIMD represents an organization that includes many processing units under the supervision of a common control unit. 4. Parallel processing is established by distributing the data among the multiple functional units. 5. RISC is a complex instruction set computer. 1. A number of different algorithms can exist for solving a computational problem, and each of these algorithms could have a same running time complexity. 2. The divide-and-conquer algorithm is a bottom-up technique that usually begins by solving the smallest subproblems, the dynamic programming solves problems in a top-down fashion. 3. An important property of arrays is that their size and shape are constant. 4. If all of the elements stored in a list are of the same type, then the list is said to be heterogeneous. However, if different types of elements are stored in the list, then the list is said to be homogeneous. 5. A queue is a dynamic set that obeys the LIFO property. 1. The computer hardware recognizes only assembly language instruction. 2. A program written in the assembly language of one microprocessor can run on a computer that has a different microprocessor. 3.
