Network Topology
Cards in this deck (6)
- 1Bus TopologyLayout Structure: A single fibre optic cable connect 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 any point either start, end or middle; the quality of the connection is poor. - 2Star 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.
Drawback: The cost to implement the network is expensive because of the amount of cable needed. - 3Ring TopologyLayout structure: computers are laid out in a ring shaped structure similar to a bus however the computers are connected with a coaxial cables
Benefits: Cheap to install.
Drawback: The quality of the signal can be affected by the noise generated by the coaxial cables. - 4Bus Topology Full Lost Of Advantages And DisadvantagesAdvantages:
-Easy to install
-Easy to add extra workstations
-Uses less cable than a Star networks
Disadvantages:
-If there is a problem with the central cable, the entire network stops working - 5Ring Topology Full List Of Advantages And DisadvantagesAdvantages:
-Transmission of data is fairly simple as it only travels in on direction
-No data collision
-Extra computers can be added easily with little effect on performance
Disadvantages:
-If a single machine is switched off, the network does not 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. - 6Star Topology Full List Of Advantages And 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
