called . There is no or structure imposed on the data. The tables or relations are, however, related to each other. The database management system (RDBMS) the data so that its external is a of relation or tables.

三、英译汉题（每题10分，共20分）

Translate the following passage from English into Chinese:

1.The field of computer science has grown rapidly since the

1950s due to the increase in their use. Computer programs have undergone many changes during this time in response to user need and advances in technology. Newer ideas in computing such as parallel computing, distributed computing, and artificial intelligence, have radically altered the traditional concepts that once determined program form and function. In parallel

computing parts of a problem are worked on simultaneously by different processors, and this speed up the solution of the problem. Another type of parallel computing called distributed computing use CPUs from many interconnected computers to solve problems. Research into artificial intelligence (AI) has led to several other new styles of programming.

2.High-level languages are commonly classified as

procedure-oriented, functional, objected-oriented, logic languages. The most common high-level languages today are procedure-oriented languages. In these languages, one or more related blocks of statements that perform some complete function are grouped together into a program module, or procedure, and given a name such as “procedure A”. If the same sequence of operations is needed elsewhere in the program, a simple statement can be used to refer back to the procedure. In essence, a procedure is just a mini-program. A large program can be constructed by grouping together procedures that perform different tasks.

A New Parallel Algorithm for EZW

With the fast development of Internet technology and multimedia technology, digital communication technology has brought us much convenience and efficiency. But because the amount of multimedia especially image data is very big and its transmitting speed is very

limited, the transmission of multimedia has become the bottleneck of the further application of these technologies. The economical and technological condition also shows that this problem can not be solved just by hardware technology. Hence, it is necessary to apply data compression technology to reduce the amount of multimedia data and improve its transmitting speed, in order to make digital communication technology be applied more widely and to bring society more efficiency

Image compression technology originates from Shannon’s information theory in 1940s. Under this theoretical frame, several lossless encoding schemes have been developed, such as Run-length encoding, Huffman encoding, Arithmetic encoding, Dictionary encoding, etc. But the compression ratios of these lossless schemes are still very low, they can not meet most requirements of image storage and transmission. Hence, many people have widely studied lossy compression schemes, they have tried to increase compression ratio through removing the redundant information and details not sensitive to vision. In this respect, KL Transform, Discrete Cosine Transform (DCT) and other transforms have been developed early or late. But these techniques have their own drawbacks. For

example, these techniques frequently cause artifacts, such as the blocking effect in JPEG. On the other hand, since 1990s,many new transmitting media represented by Internet have set new demand on the browsing and transmission of images, such as requiring embedded code stream and multiresolution code stream. This requires image compression algorithms to provide flexibly hierarchical coding structure for image quality and resolution and so on. But such flexibility can not be provided by DCT encoding scheme.

In the late 1980s,the development of wavelet theory provided efficient tools for multiresolutional signal processing, and wavelet transform provided found basis for various hierarchical image encoding. The research of wavelet image compression has also shown that many characteristics such as multiresolution, multi-quality control and embedded code stream required in modern applications all coincide with the hierarchical structure of wavelet image encoding. At greater compression ratio,the reconstruction quality of wavelet image compression is much better than that of DCT. Hence,in the new still image compression standard JPEG2000, wavelet image encoding is adopted as a key algorithm [4].In the domain of wavelet still image encoding, Embedded Image Coding

Using Zerotrees of Wavelet Coefficients (EZW) is one of the most efficient techniques [3,5].

Although EZW is a better encoding technique, its encoding speed is very limited, because the wavelet coefficients are numerous and the coefficient structure is very complex [2].Hence, it is necessary to use parallel computer systems to speedup the computation of encoding [1].This paper just introduces a high efficient parallel EZW implemented on a PRAM-CREW model. The computational complexity of the proposed algorithm is obviously lower than that of sequential EZW and many other existed parallel EZWs.

三、英译汉题（每题10分，共20分）

1、由于计算机使用的增加，自20世纪50年代以来，计算机科学领域发展迅猛。作为对用户需求和技术进步的响应，计算机程序在这一时期经历了许多变化。计算领域的新思想，如并行计算、分布式计算和人工智能，从根本上改变了一度决定程序形式与功能的传统概念。在并行计算中，一个问题的组成部分由不同的处理器同时处理，这样就加快了问题的解决速度。一种称为分布式计算的并行计算，使用多个互连计算机的中央处理器来解决问题。人工智能研究已经带了来其他几种新的编程风格。

2.高级语言通常分为面向过程的语言、函数式的语言、面向对象的语言或逻辑语言。如今最常用的高级语言是面向过程的语言。在这些语言中，一个或多个相关的执行某种完整功能的语句块被组织成一个程序模块或过程，并被给予诸如“procedure A”这样的名字。如果程序中别的地方需要同一个过程，就可以用一个简单的语句来调用该过程。实质上，一个过程就是一个小小的程序。可以将执行不同任务的过程组合起来构成一个大程序。

四、汉译英题（20分）

The most notable example of an internet is the Internet ，which originated from research projects going back to the early 1960s. The goal was to develop the ability to link a variety of computer networks so that they could function as a connected system that would not be disrupted by local disasters. Most of this original work was sponsored by the U.S. government through the Defense Advanced Research Projects Agency (DARPA). Over the years, the development of the Internet shifted from a defense project to an academic research project, and today it is largely a commercial undertaking that links a worldwide combination of WANs, MANs, and LANs involving millions of computers.

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.
