一个完整的计算机系统,应当包括硬件系统和软件系统。也就是说,硬件和软件结合起来,计算机才能发挥作用。在学习计算机时,我们经常见到“硬件”和“软件”两个术语,那么,什么是“硬件”和“软件”,它们有什么用途呢? 什么是硬件和软件硬件是指构成计算机的物理设备,即那些看得见的实体“部件”。如:主机、键盘、显示器等,硬件也称“硬设备”。我们知道,计算机的每个基本动作都是按照指令去做的。所谓“软件”就是把成千上万条指令一条条编纂起来,形成一个整体去完成某项复杂的任务。打个比方,如果计算机是钢琴,那么每个琴键的音符就是一条指令,由音符编成的乐谱就是软件。在计算 A complete computer system should include both hardware and software systems. In other words, the combination of hardware and software, the computer can play a role. When learning computer, we often see the two terms “hardware” and “software”, then what are the “hardware” and “software”, what are their use? What is hardware and software Hardware refers to the physical Devices, those visible entity “parts.” Such as: host, keyboard, monitor, etc., hardware is also called “hard device”. We know that every basic action of a computer is done as instructed. The so-called “software” refers to the compilation of thousands of directives to form a whole to accomplish a complicated task. For example, if the computer is a piano, then the note for each key is an instruction, and the score compiled from the notes is the software. In calculation
