Computer Network Outline

BUS TOPOLOGY A network topology that is generally in a line formation, which uses several devices that are all connected to a common central cable called a bus and commonly used for LAN’s. Component Description Usually 2 or more desktop of notebook computers with a network interface card. A common printer is shared by all desktops or notebook computers. The server process requests and delivers data to the client computers over the internet or network. Advantages The network is cheap to install. It is easy to add new devices to the network. The topology is useful for temporary of small networks. The network is cheaper to maintain. If the main cable fails the network will go down. The network is slower than other topologies. RING TOPOLOGY A network topology in which devices are connected in a ring formation and generally used for LAN’s. Component Description This network usually has 2 or more desktop of notebook computers with network interface cards. The printer is shared by all other computers. The server processes requests and delivers data to the client computers over the internet of network. Advantages This network can perform better than the star topology under heavier loads. Larger networks can be created on this kind of topology. This network does not need a network server to manage the computer connectivity. Disadvantages The network is fairly difficult to install. The network is more expensive than other topologies. Additions or changes of devices can affect the network. STAR TOPOLOGY A Network topology where each device is connected to a hub in a pattern that resembles a star, which has a hub at the center. The hub is a special type of hardware that receives data and routes it to the proper
