In TDM‚ incoming signals are divided into equal fixed-length time slots. After multiplexing‚ these signals are

Analysis and Countermeasures of Network Security LiuBingyao Abstract This article is concerned about network security. It mentions about the present situation of network security and an analysis of the reason that lead to unsafe network environment. Then the article introduces two frequently used protocols in network security: HTTP (Hypertext Transport Protocol) and HTTPS (Hypertext Transfer Protocol over Secure Socket Layer)‚ then compare them and give a brief conclusion. On the other side

large number of other nodes‚ they have the ability to measure a given physical environment in great detail. Thus‚ a sensor network can be described as a collection of sensor nodes which co-ordinate to perform some specific action. Unlike traditional networks‚ sensor networks depend on dense deployment and co-ordination to carry out their tasks. Previously‚ sensor networks consisted of small number of sensor nodes that were wired to a central processing station. However‚ nowadays‚ the focus is

Network Address Translation Design and Implementation Abstract—This is the final report for a research project covering network address translation (NAT). Research topics include: the history and necessity for NAT‚ overall design‚ implementation‚ the different types‚ and examples of its use. Keywords—NAT; networking; project; research Necessity IP addresses were originally designed to be globally unique. In an IP network‚ each computer is allocated a unique IP address. In the current

Design of a Network When a network is being designed‚ the architect must first think about the logical layout and that should be enforced. When he figures out what devices need to communicate and how‚ a physical design of the network can be implemented. A logical design is the reasoning of a network‚ with no particular devices or locations chosen. The physical design of the network is when the devices are picked and their actual location determined. When the logical design of a network is planned

INTRODUCTION TO NETWORK TYPES Research Paper #1 Prepared for Professor Jewett Prepared by Anissa Truitt COOP Semester: Spring 2007 The article basically describes the different types of networks. It states "nearly every type of design is referred to as an ¬area network". The main networks discussed are‚ LAN and WANs. According to the article‚ these were the original categories of area networks. LAN‚ which stands for Local Area Network‚ connects devices over a relatively short

people in various places. Companies can get many advantages by using Internet network to support their business. Therefore‚ companies are trying as hard as they can‚ and give high effort in protecting their network from attack and make sure that they have the best network security. Most people think that the threat of security attack is only come from outside the company. In fact‚ the attack from inside the company network is more harmful with high frequency to be happened.
