1、1)Computer systems for use in electronic circuits and physical device, is almost tangible entities, such as the central processing unit (CPU), storage, an external device (input/output devices, I/O devices) and bus, etc.(1) the memory. The main function is to store programs and data, the program is 。

2、the basis of computer operation, data is computer operation of object. Memory is by memory, address decoder, literacy control circuit, the address bus and the data bus composition. Can directly by the central processor instructions and data of random access memory says mainly memory, disk, tapes and。

3、 CDS etc mass storage called external memory (or auxiliary storage). By the main memory, external memory and the corresponding software, composed of computer storage systems.(2) the central processors main function is to press exist within the memory program, headed to execution procedures specified。

4、 by the operation. The central processor main component are: data registers, instruction register, instruction decoder, alus, operating controller, the program counter (instructions address counter), address register, etc.(3) an external device is a bridge between the user and the machine. The input。

5、 device task was to user requirements of computer processing of data, characters, words, graphics and the procedure of various forms of converting information for the computer can accept coding form to inside a computer deposit. Output devices task was to computer processing results to the needs of 。

6、user form (such as screen, text printing, graphic charts, language acoustics) output. Input/output interface is an external device with CPU between the buffering devices, responsible for electrical properties of matching and information format conversion.计算机系统中所使用的电子线路和物理设备，是看得见、摸得着的实体，如中央处理器( CPU )。

7、、存储器、外部设备(输入输出设备、IO设备)及总线等。 存储器。主要功能是存放程序和数据，程序是计算机操作的依据，数据是计算机操作的对象。存储器是由存储体、地址译码器 、读写控制电路、地址总线和数据总线组成。能由中央处理器直接随机存取指令和数据的存储器称为主存储器，磁盘、磁带、光盘等大容量存储器称为外存储器(或辅助存储器) 。由主存储器、外部存储器和相应的软件，组成计算机的存储系统。 中央处理器的主要功能是按存在存储器内的程序 ，逐条地执行程序所指定的操作。中央处理器的主要组成部分是：数据寄存器、指令寄存器、指令译码器、算术逻辑部件、操作控制器、程序计数器(指令地址计数器 )、地址寄存器等。 。

8、外部设备是用户与机器之间的桥梁。输入设备的任务是把用户要求计算机处理的数据、字符、文字、图形和程序等各种形式的信息转换为计算机所能接受的编码形式存入到计算机内。输出设备的任务是把计算机的处理结果以用户需要的形式(如屏幕显示、文字打印、图形图表、语言音响等)输出。输入输出接口是外部设备与中央处理器之间的缓冲装置，负责电气性能的匹配和信息格式的转换。 (2)硬件是指组成计算机的各种物理设备，也就是我们在“认识计算机”中所介绍的那些看得见，摸得着的实际物理设备。它包括计算机的主机和外部设备。具体由五大功能部件组成，即：、控制器、存储器、输入设备和。这五大部分相互配合，协同工作。其简单工作原理为，首先。

9、由输入设备接受外界信息(程序和数据)，控制器发出指令将数据送入(内)存储器，然后向发出取指令命令。在取指令命令下，程序指令逐条送入控制器。控制器对指令进行译码，并根据指令的操作要求，向存储器和运算器发出存数、取数命令和运算命令，经过运算器计算并把计算结果存在存储器内。最后在控制器发出的取数和输出命令的作用下，通过输出设备输出计算结果。Refers to the hardware components of the computer equipment of all kinds of physical, that is, we know computers in the presentation。

10、 of those visible and tangible reality of the physical equipment. It includes mainframe computers and peripherals. By the specific function of the five major components, namely: computing devices, controllers, memory, input devices and output devices. The five most of each other, work together. Its 。

11、simple operating principle for the first device to receive input from the outside world of information (and data), the controller issued a directive sent to the data (with) memory, and then inward memory access instructions issued by the command. In order get an order, one by one into the controller。

12、 command procedures. Controller for instructions on the decoding, and in accordance with the instructions of the operation requirements of memory and computing devices to keep the number issued, take a few orders and order operations, after computing devices and computing results with the existence of memory. In the last check issued by the controller and a number of export orders under, the output device through the output results.(3。
