Network
Topologies
- Ring
- A ring topology is a ring network which is also a peer to peer newtork
- Advantages: The network is not dependent on a central computer, each computer has the same access as the others so no one computer can "hog" the network
- Disadvantages: If there if a break in the connection, then the whole network fails, faults are difficult to locate, it is impossible to keep the network running whilst equipment is added or removed because there is only one path for the data to follow.
- A ring topology is a ring network which is also a peer to peer newtork
- Bus
- A bus topology is all the devices connected to the network are connected to a common shared cable called the backbone.
- Advantages: Cost effective because of the small amount of cable needed, simple cable runs makes it easy to install, easy to add extra devices to the network
- Disadvantages: if more than about 12 devices are connected to the network,then the performance of the network is degraded, if there is a break in the backbone cable, then the network cannot be used
- A bus topology is all the devices connected to the network are connected to a common shared cable called the backbone.
- Star
- A star topology uses a central connection point to connect all the devices on the network together. The central connection point can be a hub, a switch or a router.
- Advantages: fault tolerant if one of the cables fails, then the other computers can still be used, load
- Disadvantages: Higher cost- the large of cabling needed makes it a more expensive topology, dependence on the central hub(switch or router) - if the device at the centre of the network fails, then the whole network with fail.
- A star topology uses a central connection point to connect all the devices on the network together. The central connection point can be a hub, a switch or a router.
- Ring
Client-Server
- Advantages
- Security is better- because it is centralised and a person is given responsibility for it
- Centralised data - data is all held on the file server which means that all users have access to the same set of data
- Disadvantages
- More expensive - servers are expensive
- Need specialist knowledge - need to have a person who understands the technicalities of a network in charge of the network
