1.3 Disadvantages of a bus topology?
The disadvantages of a bus topology are that it is unreliable and the fastest computers delay the slower computers communication with the network. A break in the network will cause the whole network not to work. The performance of the network is decreased when more computers are added.
1.4 Where are bus networks used?
Bus network are usually used at home when networking two computers together so that you can use the same internet connection and also be able to use the same printer, scanner etc.
2. What is a star topology?
A star topology is a network to which are nodes are connected directly to a hub (central device) and if any computer fails it will not affect the rest of the network.
2.2 Advantages of a star topology?
The advantages of a star topology are that it is easy to install and cable it is also cheap for installation costs. If there is a fault on one of the cables it will not affect the rest of the network and the network will not be disrupted when connecting or removing devices. The cabling that is used to cable a star network is easy to work with because it is flexible the cable used is UTP.
2.3 Disadvantages of a star topology?
The disadvantages of a star topology are the costs of setting up a star network because of the amount of cabling required and the extra devices needed to set up e.g. hubs etc. The whole network depends on the hub if this fails the network will fail.
2.4 The uses of a star topology?
The star topology is used most in banks, schools, colleges, and universities because computers can be added and removed easily. This network will also allow all users to share the uses of printers, scanners etc.
3. What is a ring topology?
A ring topology is a network in which all the computers are used to create a circle. Each of the computers in the network receives data from the previous computer and passes information received onto the next computer, this creates a ring and the ring network is known as an active network.
3.2 Advantages of a ring topology?
The advantages of a ring topology are that access to all the computers is equal and one computer cannot stop other users from accessing the network.
3.3 Disadvantages of a ring topology?
The disadvantages of a ring topology are that if one node fails the rest of the network will fail and not work. The other disadvantage of the ring topology is that it is difficult to troubleshoot or expand.
3.4 The uses of a ring topology?
A ring topology is usually used for a network, which will be highly populated, or high-speed requirements, which will pass data between the computers quickly.
4. What is a Mesh topology?
A mesh network is a network, which connects all the nodes to all the rest of the computers on the network. This will not allow a break in the network to fail the rest of the computers.
4.2 Advantages of a mesh topology?
The advantages of a mesh topology a break in the network will not cause the network to fail because a mesh topology has multiple connections. The other advantage of this network is the reliability.
4.3 Disadvantages of a mesh topology?
The disadvantages of a mesh topology is the amount of cabling required and the time required for the cabling, this makes the mesh topology had to troubleshoot and expensive to add more users.
4.4 Uses of a mesh topology?
The uses of a mesh topology are in critical situations when multiple connections between all computers are required. This will be used in nuclear plants, defence system of the country etc.
This will be used because it is very reliable and a break in the network will not cause the network to stop working.
