操作系统

说明：  操作系统是管理计算机硬件与软件资源的计算机程序，同时也是计算机系统的内核与基石。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。
(An operating system is a computer program that manages computer hardware and software resources. It is also the kernel and cornerstone of a computer system. The operating system needs to deal with basic tasks such as managing and configuring memory, determining the priority order of system resource supply and demand, controlling input and output devices, operating the network, and managing file systems. The operating system also provides an operating interface for users to interact with the system.)
