-Twisted Coaxial - 2RoutersA router will accept incoming data packets arriving from a connected Local Area Network, it will then read the destination address emedded in each data packet and work out which of the other LANs it is connected to is the best one to use for that particular data packet.
- 3SwitchA switch is a component which is used within a computer network.connected to it on each port. This piece of hardware is responsible to direct incoming and outgoing data between computers and the cloud.
- 4CoaxialCo-axial cable is excellent for carrying radio signals. The lead going from the television aerial to your television is a co-axial cable. The lead from the satellite dish to the receiver is a co-axial cable.
Some data transmission cable is co-axial, although it is used less these days for that, as twisted-pair and fibre-optic cables are more popular - 5Twisted coaxial.
- 6Fibre Optic.
- 7Bus topologyA bus topology is single line/cable with a start and end terminator. a printer and other peripheral devices can be connected on the same line.
- 8Bus topology AdvantagesEasy to install
Easy to add extra workstations
Uses less cable than a Star networks
Best choice for temporary networks - 9Bus topology disadvantagesIf there is a problem with the central cable, the entire network stops working
If there area lot of workstations on the network, data can travel slowly
Data collisions can happen as the network becomes busy
Low security- every workstation can see all of the data in the network
limited cable length and a maximum number of workstations - 10Star topologyA star topology is when
