一、分布式系统是什么
答:分布式系统是一个硬件或软件组件分布在不同的网络计算机上,彼此之间仅仅通过消息传递进行通信和协调的系统。是支持分布式处理的软件系统,能在由通信网络互联的多处理机体系结构上执行任务。它包括分布式操作系统、分布式程序设计语言及其编译(解释)系统、分布式文件系统和分布式数据库系统等。
正是因为软件的特性,所以分布式系统具有高度的内聚性和透明性。因此,网络和分布式系统之间的区别更多的在于高层软件(特别是操作系统),而不是硬件。
举个浅显的例子,例如平常用的淘宝,它本身就是一个分布式系统,用户通过浏览器访问淘宝网站时,这个请求的背后就是一个庞大的分布式系统在为我们提供服务,整个系统中有的负责请求处理,有的负责存储,有的负责计算,最终他们相互协调把最后的结果返回并呈现给用户。
二、分布式系统的优点
1、经济:微处理机提供了比大型主机更好的性能价格比;
2、速度:分布式系统总的计算能力比单个大型主机更强;
3、固有的分布性:一些应用涉及到空间上分散的机器;
4、可靠性:如果一个机器崩溃,整个系统还可以运转;
5、渐增:计算能力可以逐渐有所增加;
三、分布式系统由什么组成
答:建一个完整的分布式系统,需要六个必要的组成部分:输入节点、输出节点、网络交换机、管理节点、控制软件和运维模块。
itc分布式综合管理平台是由分布式采集器、分布式输出盒、拼接中控、分布式综合管理平台、存储服务器以及分布式综合管理平台嵌入软件组合而成,实现管理平台采集、分配、传输、交换、显示、处理和控制功能。
一个分布式综合管理平台可实现中控主机、高清矩阵、拼接处理器、局域网视频会议、KVM坐席协作、会议录播等众多系统功能。
总结:
以上便是关于“分布式系统是什么由什么组成”等的解答,简单的来说,对于用户来看分布式系统就像是一个超级计算机,希望看了这篇文章的网友能对分布式系统有个更好的理解。
