summary"with computer network technology matures, computer networking applications has become an inevitable trend in the development of the computer. Network technology to speed the development direction, broadband network has become an inevitable trend.The computer network communication technology from the 1960s, has been greatly since birth, especially the development since 1990s have developed rapidly. As is known to all, the computer network communication technology is to unexpected speed rapid development, network communication technology, the Internet also permeates gradually to people living and working in every corner. The information superhighway has direct extends to the people, the desktop, alwin in its future study TuoFuLe transfer of power masterpiece, "said: in ancient times, the strength of a country's military strength, main farmar 200 years ago, humans into industrial society, the industrial productivity, and Jordan farmar into since the 1970s, a country with knowledge of the network access storage capacity has become an important measure of its overall strength. The Clinton 11993 government announced in September, the national information highway planning. NLL (1994), National1Information1Intrasture - global information highway planning. After this, the world also has its own information highway planning, Each system in our country, and various business unit interior also raised one Internet construction boom. Along with the computer network technology matures, computer networking applications has become an inevitable trend in the development of the computer. Our government has recently proposed 12,000 years in the construction of the electronic government, the government plans to cross-century some office affairs in the Internet, improving people's government work, understand the supervision, People can inquire on the net himself about the state policies, laws and regulations, enhance the consciousness of the masses participating politics. Although the traditional 10MBPS Ethernet satisfy the demand of users at many network to a certain extent, to solve the network information resources sharing and peripheral. However, with the rapid increase of the CPU performance, workstations, user application software functions of information, network transmission of complexity and information, plus the sharp rise in the rapid development of multimedia technology in network applications, 10MBPS transmission bandwidth, already can't satisfy the development of computer technology, network transmission requirements to high-speed broadband network technology has become an inevitable trend in the development of network. The computer network in every field application, computer network communication technology, while the but for thirty years, but with human civilization has never existed before the power and speed in this world of rapid popularization, development, It is human civilization and any a kind of totem, machine, intercourse and survival of different rules is enormous, she seems to be working with echoes in the "information" fiber that create the future of the dominant force in society. The computer network will be broken, and age, economic region of cultural consumption ability, make the future society into a harmonious and unified show circle, human society will eventually into equal share of democracy, open era. Along with the computer network communication technology, the computer network, the development of social life in the fields of application, get more information becomes an indispensable part of the economy. 摘要】随着计算机网络技术的日趋成熟,计算机的网络化应用已成为计算机发展的必然趋势。网络技术向高速,宽带方向发展已成为网络发展的必然趋势。 计算机网络通讯技术从20世纪60年代诞生至今,得到了极大的发展,尤其是进入20世纪90年代以来得到了飞速的发展。众所周知,计算机网络通讯技术正在以人们意想不到的速度迅速发展着,网络通讯技术日新月异,Internet也逐渐渗透到人们生活和工作的每一个角落。信息高速公路已经直接延伸到了人们的桌面上,阿尔文·托夫勒在其未来学名著《权力的转移》中说:在古代,衡量一个国家国力的主要砝码是军事实力,200年前,人类进入工业社会以后,这一砝码变为工业生产力,而从本世纪70年代开始,一个国家拥有的存储与访问知识的网络能力已开始成为衡量其综合国力的重要指标。美国克林顿政府11993年9月公布了国家信息高速公路计划。(NLL-National1Information1Intrasture),1994年提出全球信息高速公路计划。在此之后,世界各国也先后推出了自己的信息高速公路计划;在我国各系统,各企事业单位内部也掀起了一股Internet建设的热潮。随着计算机网络技术的日趋成熟,计算机的网络化应用已成为计算机发展的必然趋势。我国政府最近又提出了在12000年建设网上电子政府的跨世纪计划,政府的一些办公事务在网上进行,提高人民群众对政府工作的监督,了解;群众可以在网上查询自己关心的国家的政策,法律法规,增强人民群众参政议政的意识。虽然传统的10MBPS以太网满足了当时许多用户的网络需求,一定程度上解决了网络资源信息和外围的共享问题。但是,随着CPU性能的迅速提高,工作站数量的增加,用户应用软件功能的不断增强,网络传输信息的日益复杂化和信息量的急剧提高,再加上迅速发展起来的多媒体技术在网络上的应用,10MBPS的传输带宽,已远远不能满足日益发展的计算机技术对网络的传输要求,网络技术向高速,宽带方向发展已成为网络发展的必然趋势。计算机网络在社会各个领域中的应用,计算机网络通讯技术虽然从诞生至今不过三十几年的时间,却以人类文明史上从未存在过的力量和速度在这世界得到迅速的普及,发展;它与人类文明史上的任何一种图腾,机器,交往方式甚至生存规则都有着巨大的不同——她似乎正用激荡在光纤中的“信息比特”预示出创造未来社会进步的主导力量。计算机网络将彻底打破地域,年龄,经济能力等对文化消费的禁锢,使未来社会展现成一个和谐统一的文化圈,人类社会将最终进入平等开放,共享民主的时代。随着计算机网络通讯技术的日益发展,计算机网络在社会生活中的各个领域得到越来越多的应用,成为信息经济时代不可缺少的一部分。

如图所示,一个近代计算机系统包括一个中央处理单元CPU,主存储器,输入设备,输出设备,副存储器和通讯设备。CPU和主存储器的特点决定了计算机处理问题的速度和能力。CPU把原始数据变成更有有用的形式,并且控制计算机系统的其它设备。在处理过程中,主存储器临时存放着数据和程序指令。输入设备,如键盘,光学扫描仪和鼠标,把数据转化成电信号输入计算机。输出设备,如打印机,显示终端把电信号转化为人可以理解的形式。副存储器存放着没有正被处理的数据。通信设备把计算机连接到通信网络上。总线是计算机各部分传输数据的通路。因特网成为关注焦点,因为他是信息高速公路应用中发展最大最快的。这里信息高速公路指提供大众收费或免费连接的国内国际范围的高速电信网络。因特网对世界商业,大学,政府机构和个人都起着巨大影响。这种影响是由于因特网几乎打破了时间和地域的局限,而且并不昂贵。
