- 1Bus TopologyA bus topology is a single cable of physical network media with several computer connected on single cable. The topology has start and end terminator.
- 2Ring TopologyA ring topology is a circle structure of computers. Each computer is connected around a single cable. All data communicated will pass on computer on the ring.
- 3Star TopologyA star topology is used in large networks with different computers and computer systems are connected with hub, server or switch. Computers receive data from the central hub, switch or server.
- 4MeshA mesh topology is hybrid structure based on the star topology. This network structure does not require switch, but multiple of cables connecting each computer. Sometimes it is referred as a spider web.
- 5VPN Virtual Private NetworkA virtual private network is used by large organisation to securely communicate information and files. A VPN is similar to a WAN by uses the internet to connect the different network together.
- 6Bus Topology Advatange= Easy to install and cheapest to buy cables.
+ Easy to expand - 7Bus Topology Disadvantage- Low Security - every workstation can sell all the data in the network.
- Data transmission can be slow if there are a lot of computers connected at the same time. - 8ring Topology Advantage+ Easy to install
+ Easy to add extra workstations
+ Uses less cable then a star network
+ Uses less cable than a star network
+ No data collisions - 9Ring Topology Disadvantage- If a single computer is switched off or faulty, the network will not work.
- Hard to dignose problems with the network. - 10Star Topology Advantage+ The most reliable topology because if one computer is switched off or fault the network will still work.
- Improved security compared to bus and ring, because the switch and hub regulate data transfer. - 11Star topology Disadvantage- Expensive network to set up because of all the hardware needed and a lot of cable to connect different computers to the hub/server/switch.
- Required experts to st up the network and for maintenance.
