audio-mail system 声邮系统
Packet switching slices messages (whether text, graphics, audio or video) into suitably sized blocks of data, like a series of letters in the mail.
分组交换将信息(不管是文本、图像、音频还是视频)分割成大小适当的数据块，好比邮包中的一系列信件。
It's like, you know, what if I just have an audio name and, you know, I put it in my E-mail and they have a chance to hear it before they meet me?
这就像，你知道，如果我有一个音频的名字，并把它放进电子邮件中去，他们就有机会在见到我前先听到我的名字。
Shut down systems when only 15-minute E-mail checks are active, or when a streaming audio connection is left playing in mute for hours.
当计算机中只有历时15分钟的电子邮件检查处于活动状态时，或者如果流音频连接在几个小时内一直处于静音播放状态，则关闭系统。
