    管理控制計算機硬件 OS是如何管理計算機硬件資源的?

    OS是如何管理計算機硬件資源的?D: 操作系統管理和控制電腦系統軟硬件資源的軟件叫做操作系統。操作系統(Operating System,簡稱OS)是管理和控制計算機硬件與軟件資源的計算機程序,是直接運行在“裸機”上的最基本的系統軟件,任何其他軟件都必須在操作系統的支持下才能運行。操作系統是用戶和計算機的接口,同時也是計算機硬件和其他軟件的接口。操作系統的功能包括管理計算機系統的硬件、軟件及數據資源,控制程序運行,改善人機界面,為其它應用軟件提供支持,讓計算機系統所有資源最大限度地發揮作用,提供各種形式的用戶界面,使用戶有一個好的工作環境,為其它軟件的開發提供必要的服務和相應的接口等。實際上,用戶是不用接觸操作系統的,操作系統管理著計算機硬件資源,同時按照應用程序的資源請求,分配資源,如:劃分CPU時間,內存空間的開辟,調用打印機等。管理和控制計算機系統軟硬件資源的軟件是什么?操作系統(英語:operating system,縮寫作OS)的作用是是管理計算機硬件與軟件資源。 它是一種計算機程序,同時也是計算機系統的內核與基石。操作系統需要處理如管理與配置內存、決定系統資源供需的優先次序、控制輸入與輸出設備、操作網絡與管理文件系統等基本事務。操作系統也提供一個讓用戶與系統交互的操作界面。 操作系統的類型非常多樣,不同機器安裝的操作系統可從簡單到復雜,可從移動電話的嵌入式系統到超級計算機的大型操作系統。許多操作系統制造者對它涵蓋范疇的定義也不盡一致,例如有些操作系統集成了圖形用戶界面,而有些僅使用命令行界面,而將圖形用戶界面視為一種非必要的應用程序。
