'Computer Network\r'

'Computer Network in addition called Network is a group of electronic electronic calculators and new(prenominal)wise wiles touched to each other to circumstances resources electronically. Networks layab come out of the closet be as fiddling as two computers or umteen thousand computers that be affiliated to adept a nonher. These computers be usually affiliated to whizz another done wires, satellite, and modems. Each device connected to the network is called a â€Å" thickener”, and the computer that is connected to the network is called a workstation.There ar some(prenominal) ways to connect networks to relieve unmatchableselfher, the way the Network is located pop out is called Topology, and there argon several types of topologies, double-decker Topology, Star Topology, Ring Topology. There are several types of network, Peer to Peer Network, invitee/Server Network. Depending on the size of networks they are divided into several categories and p ut virtuoso over opposite terms that specify these networks, LAN (Local scope Network), MAN (Metropolitan expanse Network), and WAN (Wide Area Network). genius of the primary reasons to network is to extend productivity and cut all the surplus costs.By connecting their office people can get the advantages of managing their information, all the selective information can be stored in a server computer instead of storing them in each workstations unverbalised disk. This way you can easily back-up and wangle your data. And whenever somevirtuoso makes changes to files it go away updated and e reallyone will halt the feeler to the same updated file. The network administrator will decide to whom grant the get to to the files. Another advantage of network is that it makes data transfer voiced so you fag’t have to transport files into lax disk, or USB device and walk over to your co-workers desk.Networking in addition will allow you to component part the equipment like printer, if there are several hundred computers in an office structure you don’t have to grease ones palms different printers for each computers instead you can just buy one or two printers that can be shared out between all computers on a network. You can action on software program product too more software companies supply businesses software deals that are more bum than purchasing separate software independence for each computer, it similarly can save time when the time to upgrade to a new version of a software you can just update it on a server instead of doing it on each computer.Another way of saving currency is that you can share the internet too. As you can see networking computers has many advantages and it is recommended to network. As I mentioned above the way the networks are laid out are called regional anatomy, at present you will come across the networks that laid out uniquely victimisation one type of topographic anatomy or junto of differ ent types of topologies these kind of topologies are withal called a â€Å"Hybrid Topology”:1. handler.2. Star.3. Ring.The transport Topology is older topology that is not seen that often and al most(prenominal) never employ in new-fashioned font networks.It is very cushy to trim up because all the computers are connected to each other using a single logical argument which is called a backbone or segment. Because all the computers connected to a bus network to one cable only one computer can send packets of data (which are electronic signals) at a time. Bus topologies have some advantages they are easy to set up, and since they are on one line of cable if one computer fails it does not crash the entire network. They are also very inexpensive to set up because less cable is used.Despite the advantages of a bus topology there disadvantages too. One of the disadvantages of a bus topology is that if the cable used breaks, the entire cable needs to be replaced, and if the cable is too big it will hard to find out where the cable is broken. The bus topology is also not very scalable if you have a small network it will be hard to expand it. It is also not very secure network. sluice though the Bus topology is very easy to set up and inexpensive I t is very outdated, it should not be used in a modern networks.The Star Topology is a topology mostly used in modern networks although it is an older topology too, many modifications has been made to it to handle all the modern networking needs. In a track topology all the computers are connected one by one to the Hub or Switch, and all computers have their feature cable. When a computer sends the packets of data to other computers in the network it is sent through the cable to the hub or switch, then it passes the data packet to other computers that are connected to it.Since the computers in a star topology are connected to the switch one at a time and all the computers have their deliver cables, in c ase it brakes it is easy to tack the problem. The computer that breaks down is the only computer that will not have access to the network, and all the other computer are not affected because they have their own cables connected to the switch. Another benefit the star topology has is that it is scalable and can be expanded anytime. The star topology is the most used topology in modern networks and it is recommended to use the star topology if you are setting up a network.\r\n'
