- 1Network TopologyBy Megan Thrower
- 2Bus TopologyLayout Structure ~ A single fibre optic cable connected to a multiple of computers. The computers are laid out in a straight line.
Benefits ~ The connection is speedy and clear.
Drawbacks ~ If the cable is damaged at my point either start, middle or end; the quality of the connections poor. - 3Bus Topology All Advantages & DisadvantagesAdvantages ~ Easy to install, Easy to add extra workstations, Uses less cable than a Star network, Best choice for temporary networks.
Disadvantages ~ If there is a problem with the central cable, the entire network stops working, If there are a 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. - 4Star TopologyLayout Structure ~ Computers are organised into a star shape structure with normally a switch or hub in the middle to send and receive data. Each computer is connected via fibre optic cable.
Benefits ~ If one of the cables connected to the computer breaks, the other terminals will not be affected. Speed of topology is fast.
Drawbacks ~ The cost to implement the network is expensive because of the amount of cable needed. - 5Star Topology All Advantages & DisadvantagesAdvantages ~ Star Networks are very reliable. If one connection fails. it does not affect other users, Very few data collisions as each workstation has its own cable to the server, Good security - no workstation can interact with another without going through the server first.
Disadvantages ~ The most expensive network layout to install because of the amount of cables needed, Installing the network usually needs experts to set it up, Extra hardware such as hubs and switches may be needed, If the server crashes or stops working then nobody will be able to access their files or use the network. - 6Ring TopologyLayout Structure ~ Computers are laid out in a ring shape structure similar to a bus, however the computers are connected with a coaxial cables.
Benefits ~ Cheap to install.
Drawbacks ~ The quality of the signal can be affected by the noise generated by the coaxial cables. - 7Ring Topology All Advantages & DisadvantagesAdvantages ~ Transmission of data is fairly simple as it only travels in one direction, No data collisions, Extra computers can be added easily with little effect on performance - although you have to shut down the network to be able to do this.
Disadvantages ~ If a single machine is switched off, the network doesn't work, If a cable breaks, the network doesn't work, Data must pass through every computer until it reaches its destination. This can make it slower than other network layouts, If there are any problems with the network, they can be difficult to identify the cause.
