The Wonderful Structure of a Microcomputer
In Chinese, a computer is popularly known as an " electrical brain", for the working process of a computer is similar to a human brain very much.
Just as a driver can't drive a car without driving skills or the car itself, you can't control a computer without controlling techniques or the computer itself. The controlling techniques are called software, while computers themselves and related devices are called hardware. The work of a computer is just making full use of various resources by software set in the computer, and directing the hardware to realize marvelous omnipotent functions.
Primary Components of a Microcomputer
There are many types of microcomputers. Here, we will use an IBM Personal Computer (PC) to illustrate the primary components of a microcomputer. Other brands and models of microcomputers exhibit difference in appearance and operations. An IBM PC is shown in the figure. Its primary hardware components are the main frame, the monitor, the keyboard, and many peripherals such as the disk drive, hard disk, printer, and mouse, all of which are hardwired to the main frame. The main frame is the heart of a microcomputer system. It contains the Central Processing Unit (CPU), a chip that controls the major operations of the computer and the main memory.
微型計算機的奇妙結(jié)構(gòu)
在中文里，計算機有一個人所共知的雅號：“電腦”。這是因為計算機的工作過程與人的大腦思維過程極為相似。
正像沒有汽車或者沒有汽車駕駛技術(shù)，司機就不能駕駛汽車一樣，沒有計算機或者沒有控制計算機的技術(shù)，人就不能操縱計算機。這些控制計算機的技術(shù)被叫作軟件，計算機及其各種設(shè)備本身被叫作硬件。計算機的工作就是通過計算機的軟件組，充分利用計算機的各種資源，并指揮硬件實現(xiàn)無所不能的奇妙用途。
微型計算機的主要組成部分：微型計算機種類繁多。在這里，我們用IBM個人計算機（PC）來解釋微型計算機的主要組成部分。其他品牌和型號的微機在外貌和操作上各有不同。一臺IBM PC計算機如圖所示：它的主要硬件成分是主機、監(jiān)視器、鍵盤以及許多與主機相連的外圍設(shè)備，如磁盤驅(qū)動器、硬盤、打印機、鼠標。主機是微機系統(tǒng)的核心，它包括中央處理單元（CPU）和主存，CPU是一塊控制計算機主要操作的芯片。
