Computer Networks Technology And Application In Practice

Along with fast development and compact combination of both computer technology and communication technology , computer networks technology are promoted to develop at very fast speed.People live in information society today . therefore, computer networks technology seems to be particularly important .Now, because of fast development of Internet, Virtual Private Networks technology possesses vast applied foreground.Through the current introduction of computer networks technology , this text inducts engineering programming and implementary circs of the Police Department of Liao Yang City integrated data network, and puts stress on introducing Virtual Private Networks (VPN) technology and both Virtual Private Dial-up Networks (VPDN) technology and its application.At first, the evolutionary course, constitution, sort of computer networks are introduced in the text.This paper mostly introduces theoretic knowledge of computer networks technology, including basic concept and theory ,and particularly describes network architectures, Local Area Networks and networks interconnection in Chaper 2, Chaper 3 and Chaper 4.This text mostly states engineering programming and implementary circumstances of the Police Department of Liao Yang City integrated data network in Chaper 5.According to this instance, it demonstrates the application of computer networks technology in practice.In Chaper 6, Chaper 7 and Chaper 8. This text mostly introduces VPN technology and VPDN technology. In addition, the application of VPDN technology is stated through the case that network were constructed in Welfare Lottery Ticket Issuing Center of Liao Yang City.Now, economic development tends towards global...
