Network Topologies
· Bus - This topology is an old one and essentially has each of the computers on the network daisy-chained to each other. This type of network is usually peer-to-peer and uses Thinnet (10base2) cabling. It is configured by connecting a "T-connector" to the network adapter and then connecting cables to the T-connectors on the computers on the right and left. At both ends of the chain, the network must be terminated with a 50 ohm impedance terminator. If a failure occurs with a host, it will prevent the other computers from communicating with each other. Missing terminators or terminators with an incorrect impedance will also cause problems.
As you can see if computer #1 sends a packet to computer #4, it must pass through computers #2 and #3, creating excess traffic.
ADVANTAGES: Cheap, simple to set up.
DISADVANTAGES: Excess network traffic, a failure may affect many users, problems are difficult to troubleshoot.
· Star - The star topology uses twisted pair (10baseT or 100baseT) cabling and requires that all devices are connected to a hub.
ADVANTAGES: centralized monitoring, failures do not affect others unless it is the hub, easy to modify.
DISADVANTAGES: If the hub fails then everything connected to it is down. This is like if you were to burn down the phone company's central office, then anyone connected to it wouldn't be able to make any phone calls.
· Ring - The ring topology looks the same as the star, except that it uses special hubs and ethernet adapters. The ring topology is used with Token Ring networks.
ADVANTAGES: Equal access.
DISADVANTAGES: Difficult to troubleshoot, network changes affect many users, failures affect many users.
· Hybrid - Hybrid topologies are combinations of the above and are common on very large networks. For example, a star bus network has hubs connected in a row (like a bus network) and has computers connected to each hub as in the star topology.
· Mesh - In a true mesh topology every node has a connection to every other node in the network. A full mesh network can be very expensive, but provides redundancy in case of a failure between links.
· Wireless - As the name implies, wireless networks allow computers to comunicate without the use of cables. IEEE 802.11b defines two pieces of equipment, a wireless station, which is usually a PC or a Laptop with a wireless network interface card (NIC), and an Access Point (AP),which acts as a bridge between the wireless stations and Distribution System (DS) or wired networks. An 802.11b wireless network adapter can operate in two modes, Ad-Hoc and Infrastructure. In infrastructure mode, all your traffic passes through a wireless ‘access point’. In Ad-hoc mode your computers talk directly to each other and do not need an access point at all. 802.11b delivers data throughput of 11 Mbps.
ADVANTAGES: World-wide acceptance. Ranges over 150 feet. Freedom to move about and no cables (obvious).
DISADVANTAGES: Susceptible to interference from objects such as microwave ovens and cordless phones
