Programmers connect objects by grouping them together in different classes and by grouping the classes into hierarchies. These classes and hierarchies allow programmers to define the characteristics and functions of objects without needing to repeat source code, the coded instructions in a program. Thus, using OOP languages can greatly reduce the time it takes for a programmer to write an application, and also reduce the size of the program. OOP languages are flexible and adaptable, so programs or parts of programs can be used for more than one task. Programs written with OOP languages are generally shorter in length and contain fewer bugs, or mistakes, than those written with non-OOP languages.。

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。

Westlake College in Virginia will start a laptop computer program that allows students to do schoolwork anywhere they want. Within five years, each of the1500 students at the college will receive a laptop. The laptops are part of a$10 million computer program at Westlake, a 110-year-old college. Thestudents with laptops will also have access to the Internet. In addition, theywill be able to use e-mail to “speak” with their teachers, their classmates,and their families. However, the most important part of the laptop program isthat students will be able to use computers without going to computer labs.They can work with it at home, in a fast-food restaurant or under the trees-anywhere at all!Because of the many changes in computer technology, laptop use in higher education, such as colleges and universities, is workable. As laptops becomemore powerful, they become more similar to desktop computers. In addition, the portable computers can connect students to not only the Internet, but alsolibraries and other resources. State higher-education officials are studyinghow laptops can help students. State officials are also testing laptopprograms at other universities, too. At Westlake College, more than 60 percentof the staff use computers. The laptops will allow all teachers to use computers in their lessons. As one Westlake teacher said, “Here we are in the middle of Virginia and we’re giving students a window on the world. They can see everything and do everything.”笔记本电脑在世界各地流行。

Embodied by products called codecs (compression/decompression),these methods fall into two general categories: interframe and intraframe compression.Interframe compression uses a system of key and delta frames to eliminate redundant information between frames. Key frames store an entire frame, while delta, or “difference”, frames record only the interframe changes. During decompression, the CPU builds frames from the key frames and accumulated deltas.Intraframe compression is performed entirely within individual frames. During intraframe compression, codes use a variety of techniques to convert pixels to more compact mathematical formulas. The simplest technique is called run length encoding (RLE), in which rows of adjacent identical pixels are grouped together.视频图像压缩是一组用来缩小视频图像文件大小的技术. 由被称为Codecs(压缩/解压)产品所体现的这些方法分为两大类: 帧间压缩和帧内压缩.帧间压缩利用关键帧和§帧方法来消除帧之间的冗余信息. 关键帧存储一幅完整的帧, 而§帧或”差异”帧, 仅记录帧间变化. 解压时, CPU从关键帧和累加的§帧来构造各个帧.帧内压缩是完全在个别的帧内进行的. 在帧内压缩时, Codecs使用各种技术把像素转换成更紧凑的数学公式. 最简单的技术称作行程长度编码(RLE). 按这种编码法, 各行中相邻的相同像素串归在一起.2.Data communications systems are the electronic systems that transmit data over communications lines from one location to another. You might use data communications through your microcomputer to send information to a friend using another computer. You might work for an organization whose computer system is spread throughout a building, or even throughout the country or world. That is, all the parts-input and output units, processor, and storage devices-are in different places and linked by communications.……………………你有可能在为一家公司工作,其计算机系统遍布一座大楼,或者甚至是全国乃至世界。
