常见的分布式操作系统有哪几个?不少网友对于电脑操作系统的类型都不熟悉,遇到分布式操作系统概念也是非常模糊的,其实这个也是非常常见的.那么分布式操作系统有哪些,下面给大家介绍下常见的电脑分布式操作系统.
分布式操作系统有哪些
首先我们要清楚什么时分布式系统,其实就是多个处理机通过通信线路互连而构成的松散耦合的系统。一般它们都有以下特点
一.分布性
分布式系统由多台计算机组成,它们在地域上是分散的,可以散布在一个单位、一个城市、一个国家甚至全球范围。整个系统的功能是分散在各个节点上实现的,因而分布式系统具有数据处理的分布性。
二.自治性
三.分布式系统中的各个节点都包含自己的处理机和内存,各自具有独立的处理数据的功能。通常,彼此在地位上是平等的,无主次之分,既能自治地进行工作,又能利用共享的通信线路来传送信息,协调任务处理。
四.并行性
一项大的任务可以划分为若干子任务,分别在不同的主机上执行。
五.全局性
分布式系统中必须存在一个单一的、全局的进程通信机制,使得任何一个进程都能与其他进程通信,并且不区分本地通信与远程通信,还应当有全局的保护机制。系统中所有机器上有统一的系统调用集合,它们必须适应分布式的环境。在所有CPU上运行同样的内核,使协调工作更加容易。
下面是常用的分布式操作系统
1.windows系统
windows系统是微软公司开发的,从上世纪80年的windows1.0开始,到现在的windows10,经历了漫长的30多年。windows系统的电脑,在个人电脑中占据着绝对主流的地位,全球市场占有率高达85%左右。最为典型的代表有:windows98、windowsXP、windows7、windows10。基本上4-5年会出现一个精品。windows电脑的优势:操作简单、入门快速、应用软件众多;windows电脑的缺点:吃内存厉害、对硬件要求高。
2.mac os操作系统
mac os系统是苹果公司开发的一款高性能的电脑操作系统,深受一些专业人士的喜爱和追捧。mac os系统在图形设计、影视制作等领域有着自己独特的优势,所以,我们在一些专业设计公司,大多看到的是mac os系统的苹果电脑。mac os系统目前的市场占有率达到8%左右,是目前电脑市场的第二大操作系统。现在,mac os系统也可以在普通的PC电脑上安装使用,如果只是想体验一下,可能通过windows系统的虚拟机来进行安装。
3.linux系统
linux系统,对于绝大多数人来说,是比较陌生的。早期的linux系统,跟微软的dos系统一样,是命令行字符操作模式,没有图片界面,所以,只有一些专业领域的高手才会涉及到,如:网站运维。后来,linux系统也慢慢推出了图形模式,开始在个人电脑上也能使用了,如:deepin深度系统,centos都提供有图形界面。相对于windows系统,linux系统占用硬件资源比较少,所以,大多数网站服务器会使用linux系统作为操作系统。linux系统是开源免费的。
4.unix系统
unix系统是一款付费系统,是资格最老的一款电脑操作系统,诞生于上世纪70年代。unix系统的安全性,在这几个操作系统中是最高的。目前,unix系统只有命令行界面,没有图形界面,现在大多用在企业级别的服务器上,如:银行、电信等,很多公司的研发系统也是使用unix系统平台的。还有一些操作系统是基于unix系统开发的,如:苹果的mac os系统。
这就是常见的电脑分布式操作系统介绍内容,希望能够帮助到大家。
