Networking and Interprocess Communication网络和进程间通信

The modules described in this chapter provide mechanisms for networking and inter-processes communication.本章描述的模块提供了联网和进程间通信的机制。

Some modules only work for two processes that are on the same machine, e.g. signal and mmap. 某些模块仅适用于同一台机器上的两个进程，例如signal和mmap。Other modules support networking protocols that two or more processes can use to communicate across machines.其他模块支持两个或多个进程可用于跨机器通信的网络协议。

The list of modules described in this chapter is:本章描述的模块列表如下：

• asyncio — Asynchronous I/O异步I/O
• socket — Low-level networking interface低层网络接口
• ssl — TLS/SSL wrapper for socket objects套接字对象的TLS/SSL包装器
• select — Waiting for I/O completion等待I/O完成
• selectors — High-level I/O multiplexing高级I/O多路复用
• signal — Set handlers for asynchronous events设置异步事件的处理程序
• mmap — Memory-mapped file support内存映射文件支持
