需要详细描述频道
问题描述：
大家好。所有人都可以给我一个关于频道的详细描述吗？（也就是像文件频道，套接字频道等等）或者给我关于它的相关链接。另外，我想知道：
1.操作系统如何实现通道，是否需要支持任何硬件？
2.它与流有什么不同，在什么情况下，我应该使用它而不是流？它有什么优势？
感谢所有人。

你可能想在这里阅读：

或者进一步解释你在谈论什么样的频道。有许多名为频道的东西，以确定你的目的。

Or explain further more what kind of "channel" you are talking about. There are to much things named "channel" to be sure what you're about.
