Computer Networks NETWORKING CONCEPTS Network A network is basically an interconnection of various points to make a connected system e.g Road‚ Telephone‚ Social Data Network A computer network therefore refers to an interconnection of computers and other peripherals by use of a communication link Peer to Peer Networks In a peer-to-peer network‚ all computers are considered equal; they all have the same abilities to use the resources available on the network. Peer-to-peer networks are designed

staff. In order to begin the process of planning the new network‚ we will begin by planning the network IP addressing scheme. It is very important that the network IP addressing scheme be clearly defined in order for IT administrators to locate computers promptly. Also‚ in order to make it easier for the administrators‚ DHCP (Dynamic Host Configuration Protocol) will be used to assign IP addresses. The organization of the subnet layout will assist the IT administrators as well as making effective

CHAPTER 2 METHODOLOGY This chapter discusses the network design methodology‚ scope and delimitation‚ data gathering techniques‚ and sources of data used in the study. Network Development Methodology The researchers used the Top-down Methodology for this study. Before‚ a data communications project even gets to the formal feasibility studies which are part of the development methodology that is proposed‚ it is useful to make a top-down‚ qualitative evaluation of a proposed data communications

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

Network Topologies Network topologies are an important part of the network. Without the proper topology‚ the network may not meet the needs of the organization. The layout of a network is referred to as the topology. How nodes in a network are connected to each other and communicate is determined by the topology. There are three basic topologies with several typical variations‚ or combinations. A description of four topologies follows. Mesh Topology Mesh topology is the first topology discussed

Introduction S ocial network industry started to expand rapidly after the year 1997 where the world first social network site‚ SixDegrees.com is being introduced to the public. Afterward there were many different types of sites being introduced to public. Social network sites (SNSs) can be define as web-based services that allow individuals to construct a public or semi-public profile within a bounded system‚ articulate a list of other users with whom they share a connection‚ and view and traverse

Introduction: Computer and network security is a new and fast moving Technology and as such‚ is still being defined and most probably will always be “still defined”. Security incidents are rising at an alarming rate every year [Figure - 1]. As the complexity of the threats increases‚ so do the security measures required to protect networks. Data center

sense multiple access with collision detection)‚ meaning multiple stations sense the carrier at the same time and send data when the carrier is free. However‚ there might be multiple stations sending a free carrier and send the data at the same time‚ causing "collision." Collision is the main factor affecting ethernet’s performance. The more stations on the same LAN‚ the higher the collision rate‚ the lower the performance. Token Ring‚ on the other hand‚ is based on a control/access given to the

It is impractical for an organization to own an entirety of a WAN because a WAN is decentralized It’s l for an organization to own an entire LAN‚ or local area network‚ for business expansion purposes. This is control over a dedicated section of the local network that other businesses will want to buy into. 7.1.2 Increasing the required transmission distance
