Housed within the system unit, a sound card contains connectors that project from the back of the computer so that you can attach speakers, headphones, and a microphone. Expensive sound cards include circuitry for special audio effects, such as 3-D sound. The quality of your computers speakers and headphones can also affect the quality of the sound that you hear 声卡为计算机提供了录制与放映声音文件的功能,作用类似于录音带。声 卡安装在系统机箱内,它在计算机后面有一些突出的接口,可供用户将扬 声器、耳机和麦克风插在上面。机器配置的扬声器和耳机的质量也会影响 到你听到的音质。 《什第机专出美语 -6

Multimedia elements-especially videos-require lots of storage space Rather than store huge amounts of multimedia data on a computer hard disk, the data can be stored on a CD-ROM, which you insert only when you want to access the multimedia elements. a dvd drive can access multimedia data from CD-RoMs as well. A dVd also allows you to watch feature-length movies on your computer. CD-RoM驱动器允许计算机访问光盘内的音频和软件特别是视频需 要大量的存储空间。人们并不把大量的多媒体数据存储在电脑硬盘上,而 是存放在只读光盘上,只有需要访问多媒体数据时,才将光盘插入驱动器。 个DVD驱动器可以访问 CD-ROM中的多媒体信息,也能让你在计算机 上观赏高质量的电影。 《什第机专出美语
