What is Multimedia
Multimedia means that computer information can be represented through audio graphics，image，video，and animation in addition to traditional media，such as texts and drawings. All of the technologies make computers more interesting and much easier to use .The most important technologies are as the following
CD-ROM is an optical technology that is used to make compact disks for CD stereo systems. It has now been adapted to store data for computers .CD disk is an optical disc ,on which the dips, the reflected distortion represents the data. Optical disc has a 600 megabyte capacity and is well suited for the computer applications needing the vast storage. The playback effect of optical discs for music is perfect ,no hiss and crackle as with other photo records. A computer system must nave a CD drive that is designed to read the disks and translate the data into f form it can process. CD disks can store huge volumes of data and are very useful for reference materials-an encyclopedia, for example. However, as the name (read-only memory) implies, CD disks cannot be written on or changed in any way.
Musical Instrument Digital Interface, or MIDI is a communication interface provided for every synthesizer made today .It provides a standard that allows products by different companies to communicate with each other. MIDI ‘s original purpose is to allow a musician to control several synthesizers from one keyboard rather than connect a number of keyboard –equipped synthesizers., to produce the multilayered sound. The MIDI standard provides for 16 channels. You can assign each channel to a specific synthesizer or synthesize voice. If you record a sequence and assign it to channel five, for example., only an instrument set to listen on channel five plays back the sequence . This feature enables MIDI networks to sound like orchestras.
An audio (sound) wave is a one-dimensional acoustic (pressure) wave. When an acoustic wave enters the ear, the eardrum vibrates, causing the tiny bones of the inner ear to vibrate along with it ,and sending nerve pulses to the brain. These pluses are perceived ad sound by the listener. Audio waves can be converted to digital form by an ADC (analog digital converter). An ADC takes an electrical voltage as input and generates a binary number as output . Music, of course , is just a special case of general audio, but an important one. The representation, processing, storage, and transmission of such audio signals are a major part of the study of multimedia systems.
In fact, virtual reality is exploiting software and hardware of the computer to generate a simulation of an environment, such as an easeful classroom, a breathtaking action and so on. In such a simulated environment , one would have an immersed sense and undergo all experiences in the space. His or her various senses in the realistic world would be replaced with a series of new electric stimuli.。

差不多就是这样了！！！
什么是多媒体
多媒体是指计算机信息可以通过声音来表示图形，图像，视频，除了传统媒体动画，如文本和图纸。所有这些技术使计算机更有趣，更容易使用。最重要的技术如下
CD - ROM是一种光学技术，用于制造CD立体声系统的光盘。它现在已经适应了计算机存储。CD光盘数据光盘，在其中的倾向，反映失真的代表数据。光盘的容量600兆，并同时为广大计算机需要存储应用的理想选择。在音乐光盘播放效果是完美的，没有嘶嘶声和裂纹与其他照片记录。计算机系统必须殿的CD驱动器，用于读取磁盘并将其转化为F形式可以处理数据。 CD盘可存储大量数据，是非常有用的参考资料，一本百科全书，例如。然而，正如其名字（只读存储器），这意味着，CD盘不能写，或以任何方式改变。
乐器数字接口，或MIDI是一个通信接口，每合成器提供的今天。它提供了一个标准，让不同公司的产品相互沟通。的MIDI的原目的，是让一个音乐家来控制从一个键盘，而不是连接的键盘数字装备合成几个合成器。，产生多层次的声音。在MIDI标准规定了16个通道。您可以指定每个通道特定合成或合成的声音。如果您录制序列并将它分配给渠道五项。例如，只有仪器设置，听取频道5次回序列。此功能使网络的MIDI听起来像是乐团。
音频（声音）波一维声（压力）波。当声波进入耳朵的鼓膜振动，导致内耳微小的骨头振动与它一起，和神经脉冲发送到大脑。这些利弊被视为广告的监听声音。音频波可以被转换为数字形式的ADC（模拟数字转换器）。一个ADC采用电作为输入电压产生一个二进制数作为输出。音乐，当然，只是一个普通的音频特殊情况，但一个重要的。的代表，处理，存储和传送这些音频信号是对多媒体系统研究的主要部分。
事实上，虚拟现实是利用软件和计算机硬件产生的环境仿真，如逸教室，以惊人的行动等。在这种模拟环境中，有一个人会沉浸感，在空间进行的所有经验。他还是在现实世界的各种感觉，她将取代新电刺激系列。。

英语不难，关于多媒体的。但是才10分的话，没兴趣翻了
