Computer Networks
What is a computer network? In simple terms, a computer network is a group of connected computers that allow the sharing of information and equipment. The most ordinary network is made up of two computers connected by some kind of cable in order to exchange information more quickly and efficiently. A standalone computer is very useful to many businesses, but without a network, those businesses would have to spend twice the amount of money then they would have to by having a network. A network allows many computers and peripheral devices such as printers and facsimile machines to be connected to each other. The two primary benefits of computer networking are sharing devices and data sharing.There are two basic types of networks: peer-to-peer and server-based. On a peer-to-peer network, any computer can act as a server to share resources with other machines and as a client to access resources from other machines. On the other hand, server-based networks require a server computer whose job is to respond to requests for services or resources from clients elsewhere on the network. Server-based networks are used in many and most organizations today. Although there is much advantage to server-based networks such that it ce
This goes for the ring topology method as well. The ring topology networks are constructed when a cable, forming a circle connects all the computers to each other. But as everything else has a flaw, so does a ring topology network. The entire network will fail if one computer in the ring fails, unless it is in a dual-ring network, where the network can operate around a failure. Over all, thinnet is a better choice out of the two. One of the greatest and most common disadvantages is server failure. A bus topology consists of computers connected along a single cable segment. This may also rise expenses, but in the long run it may turn out to be very profitable. A hub is a central unit that is used to retransmit a signal, which is sent from one computer to another. If the hub fails, the network fails. There are three basic types of topologies: bus, ring, and star. The ring topology uses something called token passing. Unlike coax thinnet and thicknet cables that have a maximum range of 185 to 500 meters respectively. Fiber-optic cable is an excellent networking media but very expensive as well.
