Comptuer Network Design Example Comptuer Network Design â€" Assignment Example > (UNIVERSITY)IntroductionComputer networking is the communication of two or more computers that are in a network. This process is very important as it enables the computers that are in the network share resources such as printers, files or data. We have several types of computer networks depending on the criterion adapted to classify them. They can be grouped according to the following characteristics; Classification By ScaleIn this classification they can be categorised according to the geographical area they cover. They can be classified as Local Area Network (LAN), Metropolitan Area Network (MAN) or Wide area network (WAN). In a LAN network it involves communication of computers within a small geographical area. This can comprise of the kind of network that is done at a home or an office to enables the computers to share resources such as printers, files or games. www. ethernet. intelligent. infoIn a MAN network it covers a much bigger area such as communication of computers wit hin a town or between one town and another one. This network is common in campuses to enhance a good communication of the various university campuses to facilitate good administrations, as they can be able to share the necessary resources among the campuses present. WAN network involves communication within a large geographical area. This communication can be either between one country and another one or it can be between continents. Connection MethodsThe networks can also be grouped according to the method adapted to enable communication within the network. In this classification they can be grouped into two classes that is wired network or wireless network depending on whether the network uses wires to allow communication in the network such as in the case of wired network or it uses electromagnetic spectrum to allow communication as in the case of wireless network. (Ronald J. 1998)Network TopologyThis is the classification according to the way the computers are designed to comm unicate with each other. The topology can vary as the following; the topology used can be a star, bus or ring topology. All these types of topology require different designing requirements and posses’ different merits and demerits. Functional RelationshipComputers in a network can have one of these relations. Pear-to-pear relation, in this relation instruction flows from one computer to the next in a network. In this method a failure of one computer will cut down the communication between the other computers in the network. Client-server relation, communication here is controlled by the server which determines the information to be shared and restricts the one that is sensitive to the organisation from been shared within the network. In this relationship a failure of one computer in the network will not affect the communications of the computers, as the server is the one that controls the communication of all the computers in the network. Types of ProtocolsComputers in a network can use the following protocols to enable them communicate. These are OSI or IP/IPT. Types of Hardware used in designing a network
