COMPUTER NETWORKS: A computer networks is a communication system connecting two or more computers that work together to exchange information & share resources. A network may consist of microcomputers or it may integrate microcomputers or other devices with large computer. Networks can be controlled by all nodes co-ordinarily & supply all resource. These networks differ in geographical size. There are three important types of networks. 1. Local Area Network 2. Metropolitan Area Network 3. Wide

Wireless Network Security Partha Dasgupta and Tom Boyd Dept. of Computer Science and Engineering Fulton School of Engineering Arizona State University partha@asu.edu‚ tboyd@asu.edu Abstract Wireless networking is inherently insecure. From jamming to eavesdropping‚ from man-inthe middle to spoofing‚ there are a variety of attack methods that can be used against the users of wireless networks. Modern wireless data networks use a variety of cryptographic techniques such as encryption and authentication

Effects of Social Networks on our youth. There are many negative effects that social networks have ruined our youth. There is a large amount of our youth that have joined some form of social network. Most of our youths are using these sites as a form of communication. However‚ there are some that utilize these sites for the wrong reasons. Cyber bullying‚ online predators‚ relationship break ups‚ and social network addictions are some examples of what issues social networks can cause in people’s

Network System Proposal Through much research and thought we have put together a networking system that we felt will fulfill all of your networking needs‚ now and for the future. We have prepared this proposal with the ideology of: “Look at what your needs are now but Design and Plan for the Future.” With that in mind we have come up with a system that should far exceed your expectations with cost still in mind. Initially you asked for us to allow for a 10% expansion over the next year that was

Hierarchical Star Many home networks use the star topology. A star network features a central connection point called a "hub" that may be a hub‚ switch or router. Devices usually connect to the hub with Unshielded Twisted Pair Strengths Easy to Install‚ Flexible IF single device or cable failure will not bring down the network Weakness If the centralize device fails the entire system is affected Bus Bus is the simplest network topology. All computers are connected to a single cable that

C H A P T E R 3 RESISTIVE NETWORK ANALYSIS hapter 3 illustrates the fundamental techniques for the analysis of resistive circuits. The chapter begins with the definition of network variables and of network analysis problems. Next‚ the two most widely applied methods— node analysis and mesh analysis—are introduced. These are the most generally applicable circuit solution techniques used to derive the equations of all electric circuits; their application to resistive circuits
