A文:
MIDI enables people to use multimedia computers and electronic musical instruments. There are actually three components to MIDI, the communications "protocol ", the Hardware Interface and a distribution format called "Standard MIDI Files". In the context of the WWW, the most interesting component is the Audio Format. In principle, MIDI files contain sequences of MIDI Protocol messages. However, when MIDI Protocol messages are stored in MIDI files, the events are also time-stamped for playback in the proper sequence. Music delivered by MIDI files is the most common use of MIDI today.
B文:
Certificates are digital documents attesting to the binding of a public key to an individual or other entity. They allow verification of the claim that a given public key does in fact belong to a given individual. Certificates help prevent someone from using a phony key to impersonate someone else. In their simplest form, Certificates contain a public key and a name. As commonly used, a certificate also contains an expiration date, the name of the CA that issued the certificate, a serial number, and perhaps other information. Most importantly, it contains the digital signature of the certificate issuer. The most widely accepted format for certificates is X.509 , thus, Certificates can be read or written by any application complying with X.509.欢

音乐设备数字接口 使人们可以使用多媒体计算机和电子音乐设备。实际上这里有三个组成部分，交流用的协议，硬件接口，还有叫做“标准MIDI文件”的格式。互联网上最有趣的组成是音频格式。在原则上，MIDI文件包含MIDI协议信息的序列。when MIDI Protocol messages are stored in MIDI files, the events are also time-stamped for playback in the proper sequence。（大意是虽然MIDI文件有协议的信息，但只能重复的播放固有序列。）现在MIDI格式的音乐文件成为最普通的格式。
