在刚发明计算机的时候,由于技术和工艺水平的限制,计算机是一个庞然大物,所有的软件也都集中在里面。到了20世纪80年代初,PC机的出现推动了计算机应用的普及和网络化的发展。到80年代末,随着计算机局域网的兴起,诞生了一种新型的企业计算模式,这就是著名的客户机/服务器(Client/Server)结构。在服务器上,存储和处理各种信息,最常用的是文件服务器、打印服务器和数据库服务器;在客户机端,使用的设备称为工作站,一般采用个人计算机,只负责信息的输入输出和简单操作。随着Internet的发展,出现了代理服务器、Web服务器和电子邮件服务器等。为了提高服务器的效率,又发展了机架式服务器。在企业的信息系统中,服务器是心脏,各种应用都是通过服务器完成的。
At the time of the invention of the computer, the computer was a monster and all the software was concentrated due to technical and technological limitations. By the early 1980s, the emergence of PC promoted the popularization and networked development of computer applications. By the late 1980s, with the advent of computer local area networks, a new type of enterprise computing model was born that is known as the Client / Server architecture. On the server, storage and processing of various information, the most commonly used file server, print server and database server; the client side, the device used is called a workstation, the general use of personal computers, only responsible for information input and output and simple operation . With the development of the Internet, there have been proxy servers, Web servers and e-mail servers. In order to improve server efficiency, but also the development of a rack server. In the enterprise information system, the server is the heart, a variety of applications are done through the server.
