COMMUNICATION NETWORK Communication network are large system distributed in wide area which are designed to send and receive information from one computer to another computer and this computers are called host. Network achieves this providing a set of rules which in terms of networking are called protocols. This protocols are set for communication which every host should follow and participate. The network is made up of two types of components: Nodes and

1. Introduction With the rapid development of new communications technology and network technology‚ some industries such as information industry show significant network externality characteristics. Network externality has been defined as "a change in the benefit‚ or surplus‚ that an agent derives from a good when the number of other agent consuming the same kind of good changes" (Liebowitz & Margolis‚ 1996). In other words‚ the product will be more valuable if more people use it. For example

INTRODUCTION In today’s modern world computer networks are the basic source of information exchange for all types of businesses. Different technologies are used within the context of networking depending on the requirements of an organization. Ethernet is off course the best technology for the “local area network” (LAN)‚ but when the organization spread their business to much longer distances (cities) then WAN technologies need to be deployed to keep the business running. The selection of an appropriate

CHAPTER TWO NETWORKING SYSTEMS AND LOCAL AREA NETWORKS (LAN) A network is a system of two or more computers that are connected in some manner. Each computer on the network has access to the files and peripheral equipment (such as printers or modems) on all the other computers on the network. The origin of local area networks can be traced‚ in part‚ to IBM terminal equipment introduced in 1974. At that time‚ IBM introduced a series of terminal devices designed for use in transaction-processing

computer network Connects three office computers and one computer used for Point-of-Sale (POS) services at each of your stores. You also want six (6) computers in the lobby/store where patrons can download music and you can run “training classes” for people to learn about using MP3 players and get other basic information. The two offices have to be connected into one cohesive network‚ sharing POS services and other critical company information. You also need to provide a “hand out” casual

BUTTERFLY NETWORK Butterfly network is a network with 2q nodes and q + 1 columns as an unfolded q-cube in order to facilitate the discussion‚ visualization‚ and analysis of hypercube routing algorithms. However‚ a butterfly network can be viewed as a parallel processing architecture in its own right. A butterfly architecture (Fig. A‚ left) has p = 2 q(q + 1) processors of maximum degree d = 4‚ a diameter of 2q = ∪(log p)‚ and a bisection width of ( – 1)2 q+1 + 0(2 q) = ∪(p/log p). A wrapped
