对于刚接触电脑的网友来说,可能有些网友还不了解自己经常接触的电脑操作系统。那么什么是操作系统?操作系统主要功能是什么呢?下面小编就给大家介绍下电脑操作系统的功能和概念。
工具/原料
系统版本:Windows10
品牌类型:荣耀 MagicBook Pro 2020
一、操作系统(operation system,简称OS)是管理计算机硬件与软件资源的计算机程序。操作系统需要处理如管理与配置内存、决定系统资源供需的优先次序、控制输入设备与输出设备、操作网络与管理文件系统等基本事务。操作系统也提供一个让用户与系统交互的操作界面。
二、操作系统的功能主要包括以下几个方面的功能 :
1.进程管理,其工作主要是进程调度,在单用户单任务的情况下,处理器仅为一个用户的一个任务所独占, 进程管理的工作十分简单。但在多道程序或多用户的情况 下,组织多个作业或任务时,就要解决处理器的调度、 分配和回收等问题 。
2.存储管理分为几种功能:存储分配、存储共享、存储保护 、存储扩张。
3.设备管理分有以下功能:设备分配、设备传输控制 、设备独立性。
4.文件管理:文件存储空间的管理、目录管理 、文件操作管理、文件保护。
5.作业管理是负责处理用户提交的任何要求。
总结
以上就是操作系统和主要功能的介绍。希望能帮助大家!
