在VLSI及微处理机技术不断发展的推动下,计算机系统的体系结构又经历了一次重大变革,即由两台以上的计算机(这里主要说的是微型机)组成计算机的分布式系统。目前,由于分布式系统仍然处在发展、完善之中,关于什么叫分布式系统在学术界仍有争论,因此还很难给分布式系统下一个准确的定义。但有一点是为大多数人所公认的,即分布式系统必须满足下述四个条件。1、系统由两台以上的计算机构成。构成系统的各台机器可以是大型、中型、小型或微型的。
Driven by the continuous development of VLSI and microprocessor technologies, the architecture of the computer system has undergone a major transformation. It is a distributed system composed of two or more computers (mainly referred to herein as microcomputers). At present, as distributed systems are still under development and improvement, there is still controversy about what distributed systems are all about in academia. Therefore, it is still very difficult to define an accurate definition of distributed systems. But one thing is accepted by most people that the distributed system must meet the following four conditions. 1, the system consists of two or more computers. The machines that make up the system can be large, medium, small or miniature.
