Technically speaking, VHS videotapes fall into this description of multimedia. So do Nintendo game systems, as well as talking vending machines. Hey, for that matter most books combine text and pictures. However, this book deals with multimedia only as it applies to personal computers. More specifically, this book concentrates on multimedia under the Windows operating environment running on PC-based machines.
Multimedia is not a product; rather, it is a technology ( or more accurately a combination of technologies ). A technology is anything that makes something else more efficient. For imagine you have a list of written directions for getting to the bank. Now imagine you have a mapping application that you could use to pinpoint where you want to go (“ the bank ”). Not only could that application print out detailed instructions of how to get to the bank, it could also display a full-color image of a map to the bank, along with a brief audio segment telling you the traffic conditio

从技术层面上来看，VHS型的录像带是一种多媒体形式，正如任天堂的如同自动售货机游戏机一样，令人惊奇的是，不像其他的有图片文字组成的书籍一样，这样的书籍是以个人电脑作为多媒体展示载体的。进一步说，这样的书籍是基于WINDOWS操作环境下的运行的电脑程序。
多媒体不是一件产品，而是一项技术（确切地说应是一个技术综合体），这是一项能令其他事务更加有效运行的新技术。设想一下，你会有一张写着地址的通向你要去银行的清单，你有已经标定好你要去地方路线的建议。这样一个设备不光能展现出来你要去的地方的具体介绍，还能够显示出这个银行的全彩照片，甚至是一小段语音介绍，又或是交通状况。
这样的一个地图标注系统（让我们称他味“猫曼”）是一种多媒体形式。拥有混合文本，表格绘制和数字声音，我们不用怎么动用大脑就能轻松到达银行，又或者是其他地方，很简单不是么？

Multimedia aims at making computers easier to use. As you can see from the previous example, the added information provided by sound and color pictures will make getting to the bank faster. Say you want to go a bank in another town, or in another state. A multimedia application will usually store huge amounts of information (usually on CD-ROM), so that you can also get the same information for other communities. This type of information access makes computers much more valuable for the user. By adding multimedia to your programs, you can make computers more interesting and much more fun for the user.
