第一篇:《关于计算机硬件的作文》
(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 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 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 processor's main function is to press exist within the memory program, headed to execution procedures specified 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 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 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 ）、存储器、外部设备（输入输出设备、I／O设备）及总线等。
①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。
②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。
③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：运算器、控制器、存储器、输入设备和输出设备。这五大部分相互配合，协同工作。其简单工作原理为，首先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，然后向内存储器发出取指令命令。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 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 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 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.

第四篇:《作文：电脑》
作文：电脑 时光推进100年，一个世纪以后，电脑终极发展，人类穷尽想象，人人都能用上最为先进的电脑，这个二百多年前发现的玩意会如此影响我们的生活。
有了电脑，多好！终极电脑之断想——就只剩三个按键了！
●没有显示器，只要把开关一开，电脑会通过光线给你制作一个现成的显示器。它分辨率极高，而且响应时间超快！在墙上，在草地，在水中，甚至在空气中。{关于计算机的作文}.
●不会在安静的夜里，在昏黄的蜡烛或者灯下，静静地去读一本拿在手里的书。 ●一百年后的电脑几乎所有的输入方式都可以靠语音和意念来替代键盘，但是一百年后的电脑，还是有可能会挂掉，所以（CTEL＋ALT＋DEL）这三个按键还是要留着„„ ●有小学生在作文中如此写道：
1、50年后的电脑可以放在铅笔盒里，在铅笔盒的下层可以放铅笔之类的东西，至于上层，就是键盘，盒盖就是屏幕，鼠标就插在铅笔盒旁边。
2、你在网上购买了一件衣服，多媒体电脑会把衣服传过来；多媒体电脑还是一位医术高明的医生，有病对它说，马上就能恢复身体健康；多媒体电脑是一位高级教师，让它帮你辅导，你的学习成绩一定稳步上升；多媒体电脑还是一位厨师，只要输入原料，就能做出色香味俱全的美味佳肴。
像我这样的编辑，每天往电脑前一坐，就是十几个小时，坐得我腰疼，怀疑是不是得了腰椎间盘突出。
看个电影还好点，要是看篇论文、诗歌什么的，会看得头晕眼花、烦闷欲吐。这破玩意还放着辐射。我都担心白细胞就快降到最低值了。是谁发明的破电脑？没电脑多好！无电脑之断想—看不到芙蓉姐姐了
●假如没有电脑，我上班就不用噼里啪啦的去敲键盘了，也不用费劲的思考一个字是平舌还是翘舌，前鼻音还是后鼻音了。想和谁联系的时候，就动手写信，顺便练练书法，（我现在的手写字已经不卒忍读了）还能给邮政局创点收入，你看邮政自从和电信分了家，效益是江河日下啊。
现在，QQ和邮件霸王了我，都让我忘了怎么拿笔了，一写字就像鸡爪子似的，可怜我小学时练了半年的毛笔字功底全军覆没。几千年的书法文化竟然败给几十年的键盘文化，小编心有不甘啊。
●假如没有电脑，我去银行存钱取钱再也不用按那6位数的密码了，省得还提心吊胆的怕别人看见。到时候拿出钱来往柜台上一砸，说：“存30000块，给大爷记上。”然后就可以悠哉悠哉的看着出纳员抱着一摞子账簿记账。
●假如没有电脑，发射火箭就不用现在这么麻烦了。到时候先找几个人把火箭抬起来，然后再来个人用打火机点着火，接着总指挥喊：“一、二、三，发射！”那几个人就把火箭扔出去了。多简单，就三步。比现在又得检查这个设备又得检查那个程序的省事多了。 ●假如没有电脑，我们就不会看到那么多愤慨的事，也不会看到芙蓉姐姐那些恶心的图片。

With the help of computers, doctors can find diseases easily and solve other problems. For example, tiny computers inside people's bodies keep their hearts beating well. In factories, robots controlled by computers can do work that is dangerous to humans. Computers are also used in business to place and cancle orders.

do business at home. Instead of writting letters on paper, people communicate by sebding e-mails and chatting on line. The whole world is connected. Computers have made the world smaller, like a" village".
Computers have improved our lives, but they have brought problems,too. For instance, if we work on computers too long, we may get headaches or sore eyes.If we play computer games too much, we won't study well and get
enough exercise. Although computers help us work and at home, we must use them properly.

Recently， there have been a fight between 360 and QQ. Some netizens have been affected because of this competition. Some QQ lovers weren't able to chat online because of 360's interference. Thus, QQ lovers have been very cross about this. And the board of QQ decided to fight against 360. The QQ company said that they had to do this because the 360 company should be to blame.
In my opinion, 360 should stop interfering other softwares, such as QQ, Maxthon, Kingsoft and so on. Only in this way can we netizens enjoy the Internet more, especially for us QQ lovers

Now many of my classmates like to surf the Internet in their free time.I think Internet can bring us both advantages and disadvantages.For example，if I have some trouble studying， I can surf the internet to find more helpful information. And I can make more friends on it. Some of my classmates say they feel happy when they talk with more friends with many similar
hobbies.However, Internet can make some problems at the same time. If you spend too much time on it ,you will becaome lazy and can't put your heart on study. It will be even worse if you feel you can't live without Internet. So we must be careful when we use the Internet.
现在，我的很多同学都喜欢在闲暇的时间里上网，我认为网络既给我们带来了好处，又有不好的地方。例如，如果我在学习上又困难，我就能上网搜索一些有帮助的信息。并且我还能够在网上交到更多的朋友。我有一些同学说，当他们找到了一些拥有相当兴趣的朋友来聊天时，会觉得开心然而，网络同时也会造成一些问题。如果你花太多时间在上面，你就会变懒而且不能够专心学习。如果你觉得你的生活已经离不开它了那就更糟了所以，当我们在使用网络的时候一定要小心。

Obviously, different people have got different attitude about the internet. There are some possible reasons for the present situation. Some people think that the internet also do harmful thing to our human beings. In the first place, some people poured most of their energy in chatting on internet. it wastes much time and money. In the second place, some people watch the sexual pictures and movies on internet, which makes them down. Last but not lease, they are out of the business. the lack of physical exercise is due to the fact that people spend too much time on internet.
