摘要
当今世界,各种先进的科学技术飞速发展,给人们的生活带来了深远的影响,它极大的改善我们的生活方式。在以计算机技术为代表的信息科技的发展更是日新月异,从各个方面影响和改变着我们的生活,而其中的计算机网络技术的发展更为迅速,已经渗透到了我们生活的各个方面,人们已经离不开计算机网络,并且随着因特网的迅速普及,给我们的学****与生活条件带来更大的方便,我们与外部世界的联系将更加的紧密和快速。
局域网是各种类型网络中一大分支,有着非常广泛的应用。随着计算机的发展,人们越来越意识到网络的重要性,通过网络,人们拉近了彼此之间的距离。本来分散在各处的计算机被网络紧紧的联系在了一起。局域网做为网络的组成部分,发挥了不可忽视的作用。我们可以用Windows OS把众多的计算机联系在一起,组成一个局域网,在这个局域网中,我们可以在它们之间共享程序、文档等各种资源,还可以通过网络使多台计算机共享同一硬件,如打印机、调制解调器等;同时我们也可以通过网络使用计算机发送和接收传真,方便快捷而且经济。随着网络应用的发展计算机病毒形式及传播途径日趋多样化, 安全问题日益复杂化, 网络安全建设已不再像单台计算安全防护那样简单。计算机网络安全需要建立多层次的、立体的防护体系, 要具备完善的管理系统来设置和维护对安全的防护策略。

Abstract
in today's world, various kinds of advanced science and technology is developing rapidly, and the people brought profound influence, which greatly improve the way we live. puter technology as a representative of the development of information technology is changing from the aspects of influences and changes in our life, and the development of work technology, has more quickly permeate into all aspects of our life, people can work, and with the rapid popularization of the , we study and life conditions lead to greater convenience, we will contact with the outside world of closer and fast.
LAN is a big branch of various types, is widely used. With the development of puter, people realize the importance of work, network, and people close by the distance between people. Originally in work everywhere in tightly. As part of the work, play an important role. We can use puter to Windows OS contact together, form a LAN, in the local work, we can share in their various resources, the document procedure, but also through puters sharing the same hardware such as printer, modem, etc. At the same time, we also can puter through work to send and receive faxes, convenient and economical. Along with the development work application and dissemination puter virus ing more diverse forms, securit
