Interprocess Communication 三、进程间通信
The various activities (or processes ) executing on the different computers within a network (or even executing
on the same machine via time sharing) must often communicate with each other to coordinate their actions and to perform their designated tasks. 在一个网络内不同计算机上（甚至使用分时方法在同一台计算机上）执行的各种活动（或进程）必须经常互相通信，以便协调行动，并完成指定的任务。 Such communication between processes is called
interprocess communication. 这种进程之间的通信称为进程间通信。
A popular convention used for interprocess communication is the client/server model. 进程间通信使用的一种流行规约是客户机/服务器模型。 This model defines the basic roles played by the processes as either a client, which makes requests of other processes, or a server, which
satisfies the requests made by clients.
这种模型将进程扮演的基本角色或定义为向其他进程提出请求的客户机，或定义为满足客户机所提请求的服务器。
An early application of the client/server model appeared in networks connecting all the computers in a cluster of offices.
