什么是插座?这是一个过程吗? [英] what is a socket? Is it a process?

问题描述

我正在研究os概念，我发现套接字是通信的终点.现在到底是什么插座?它是系统进行通信的过程吗? 预先感谢

I am studying os concepts and I found socket as the end point of communication. Now what exactly is a socket? Is it a process through means of which a system communicates? Thanks in advance

推荐答案

通过阅读Wikipedia文章，我可以理解为什么您会感到困惑.

From reading the Wikipedia article, I can see why you may be confused.

套接字是虚拟设备.即，它是用软件编写的设备，没有物理设备.因此，您可以像读取终端一样读取和写入套接字.

A socket is a virtual device. That is, it is a device that is written in software and has no physical device. Thus, you can read to and write from a socket, like you would do to a terminal.

套接字成对工作以进行通信，并且通常是双向的.一个会读取套接字(A)并写入套接字(B)---或----写入套接字(A)并从套接字---或---来回读取.

Sockets work in pairs to communicate and are usually bidirectional. One reads to socket (A) and writes to socket (B) --- or ---- writes to socket (A) and reads from socket --- or --- switches back and forth.

通常，套接字用于网络通信.它们通常可以支持多种协议(TPC/IP，UDP/IP甚至DECnet，而色域取决于底层系统).

Generally sockets are used for network communications. They can usually support multiple protocols (TPC/IP, UDP/IP, even DECnet--the gamut depends upon the underlying system).

套接字也可以用于单个系统上的进程间通信.

Sockets can be used for interprocess communication on a single system as well.
