Zhang Hua: Then are there any special requirements for a computer in multimedia applications? Mr. Wang: Actually most PCs today have good multimedia features. They have dual- or single-core CPUs clocked at 3.0 GHz or faster, at least 1GB of RAM, and a 128 MB or higher video card. Popular graphics cards include Nvidia Gforce or ATI Radeon. Zhang Hua: So there is a wide selection for us now. Mr. Wang: Right. Multimedia applications were uncommon due to the expensive hardware required until the mid-1990s. However, with increases in performance and decreases in price, now they are commonplace. Of course, we can make different choices depending on our specific purposes. Zhang Hua: I see. Thank you very much for your explanation, Mr. Wang. Mr. Wang: You’re welcome.

AA制
“AA”是“Algebraic Average”的缩写。意思是“代数平均”，就是按人头平均分担帐单的意思。但香港人把AA作为All Apart的缩写，意为“全部分开”。英文中有这样一句俗语：“Let‘s go Dutch！ ”现在一般简称为“Go Dutch”,翻成中文意即为“AA制”，好像是说荷兰人天性“抠门儿”，无论做什么都会同对方算得清清楚楚，且十分推崇“AA制”。于是就把“让我们去做荷兰人”引申成为“AA制”。 algebraic [,ældʒə'breɪk]

第八单元：计算机网络Unit 8 Computer Network课文A：网络基本原理Section A Network FundamentalsThe need to share information and resources among different computers has led to linked computer systems, called networks, in which computers are connected so that data can be transferred from machine to machine.在不同计算机之间共享信息和资源的需要，导致了相互连接的计算机系统的产生。

这种相互连接的计算机系统被称为网络。

在网络中，计算机连接在一起，从而数据可以从一台计算机传输到另一台计算机。

In these networks, computer users can exchange messages and share resources - such as printing capabilities, software packages, and data storage facilities - that are scattered throughout the system.在网络中，计算机用户可以交换信息，并共享分散在整个网络系统的资源，如打印能力、软件包以及数据存储设备。

The underlying software required to support such applications has grown from simple utility packages into an expanding system of network software that provides a sophisticated network wide infrastructure. 支持这类应用所需的基本软件，已经从简单的实用软件包发展成一个不断扩展的网络软件系统，该系统提供了一个复杂的网络范围的基础结构。

计算机专业英语第八章课文翻译

CHAPTER 8 SECONDARY STORAGEP213IntroductionSecondary storage devices are used to save, to back up, and even to tran sport files consisting of data or programs from one location or computer to another. Not long ago, almost all files contained only numbers and lett ers. The demands for saving these files were easily met with low-capacity floppy disk drives and hard-disk drives.Data storage has expanded from text and numeric files to include digita l music files, photographic files, video files, and much more. These new ty pes of files require secondary storage devices that have much greater cap acity.Secondary storage devices have always been an indispensable element i n any computer system. They have similarities to output and input device s. Like output devices, secondary storage devices receive information from the system unit in the form of the machine language of 0s and Is. Rathe r than translating the information, however, secondary storage devices sav e the information in machine language for later use. Like input devices, s econdary storage devices send information to the system unit for processi ng. However, the information, since it is already in machine form, does n ot need to be translated. It is sent directly to memory (RAM), where it c an be accessed and processed by the CPU.Competent end users need to be aware of the different types of second ary storage. They need to know the capabilities, limitations, and uses of fl oppy disks, hard disks, optical discs, and other types of secondary storage. Additionally, they need to be aware of specialty storage devices for porta ble computers and to be knowledgeable about how large organizations ma nage their extensive data resources.辅助存储设备被用来保存，备份，甚至把数据或程序从一个位置或计算机传送到另一个地方。
