- 1Define the term 'node'A device on a network
- 2What is a LAN?Local area network
- 3Advantages of a LANWhat are the advantages of LAN? Nodes can be updated centrally, data sharing is convenient, easy back ups, expensive peripherals can be shared
- 4Disadvantages of LANNetwork issues will affect all users, maintenance, security issues
- 5What is WAN?Wide area network (Often 7 LAN's connected together)
- 6What is WLAN?Wireless local area network
- 7What are network hubs?Hardware that connect network devices together
- 8What's a network switch?Connect different segments of the network together through bridge for e.g.
- 9What is a bus topology?All nodes are connected to each other in series with terminators at each end to absorb excess data and prevent signal reflection
- 10What are the advantages of a bus network?Cheap. Easy to set up, not very complex.
- 11What are the disadvantages of a bus network?Data collisions may happen thus it is slow. One problem on the system that is controlling the entire network can mean that everything will stop working.
- 12What is a ring network?When data passes through each node in the network.
- 13What are the advantages of a ring network?No data collisions therefore it is fast as all the data is travelling over a certain path.
- 14What are the disadvantages of a ring network?One issue in the circle can ruin the entire network and stop the transfer of data.
- 15What is a star network?Each client is connected to the main switch/hub
- 16What are the advantages of a star network?If a problem is to occur with client, the network is not entirely ruined. Few data collisions therefore it is quite fast.
- 17What are the disadvantages of a star network?It needs expertise management. Hard to set up more. More hardware and software is required.
- 18What is a peer-to-peer network?All computers are used equally on the network. Partitions tasks and workloads between peers.
- 19What is a client-to-server network?Each node has a different job from the other. Each node will essentially act as a workstation.
