Flashcards do conjunto (11)
- 1Bus TopologyA bus topology is a single cable of physical network media with several computers connected on a single cable. The topology has a 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 computers on the ring.
- 3Star TopologyA star topology is used in large networks with different computers and computer systems are connected with a hub, server or switch. Computers receive data from the central hub, switch or server.
- 4MeshA mesh topology is a hybrid structure based on the star topology. This network structure does not require a switch, but multiple cables connecting each computer. Sometimes it is referred as a spiders web.
- 5VPN Virtual Private NetworkA virtual private network is used by large organisations to securely communicate information and files. A VPN is similar to an WAN by using the internet to connect the different network together.
- 6Bus Topology Advantages+ Easy to install and cheapest to buy cables.
+ Easy to expand.
+ Best choice for temporary network. - 7Bus Topology Disadavantages- 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 that a star network.
+ No data collisions. - 9Ring Topology Disadvantage- If a single computer is switched off or faulty, then the network will not work.
- Hard to diagnose problems with the network. - 10Star Topology Advantages+ The most reliable topology because if one computer is witched off or faulty, the network will still work.
+ Improved security compared to bus and ring, because the switch and hub regulate data transfer. - 11Star Topology Disadvantages- 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.
- Requires experts to set up network and for maintenance.
