- 1What does LAN stand for?Local Area Network
- 2What does WAN stand for?Wide Area Network
- 3Give an example of a LANA school or office network
- 4Give an example of a WANThe internet
- 5Briefly describe a file serverA device which controls access to separately stored files, as part of a multi-user system.
- 6Briefly describe a client server networkOne computer acting as a file server
- 7Briefly describe a peeer-to-peer networkA network in which all computers are of equal importance
- 8State the structure of a Bus networkIn a bus network all the workstations, servers and printers are joined to one cable (the bus). At each end of the cable a terminator is fitted to stop signals reflecting back down the bus.
- 9State the structure of a Ring networkIn a ring network each device (workstation, server, printer) is connected to two other devices, this forms a ring for the signals to travel around. Each packet of data on the network travels in one direction and each device receives each packet in turn until the destination device receives it.
- 10State the structure of a Star networkIn a star network each device on the network has its own cable that connects to a switch or hub. A hub sends every packet of data to every device, whereas a switch only sends a packet of data to the destination device.
- 11State some advantages of a Bus netoworkEasy to install.
Cheap (because it doesn’t require much cable). - 12State some disadvantages of a Bus networkIf the main cable is damaged then the whole network fails.
As more workstations are connected the performance of the network will become slower because of data collisions.
Every workstation on the network "sees" all of the data on the network – this is a security risk. - 13State some advantages of a Ring networkCan transfer data quickly.
Cheapest to create / set up.
No data collisions. - 14State a disadvantage of Ring networksIf the main cable fails or any device is faulty then the whole network will fail.
- 15State some advantages of a Star networkVery reliable – if one cable or device fails then all the others will continue to work.
High performing as no data collisions can occur. - 16State some disadvantages of a Star networkExpensive to install as this type of network uses the most cable (network cable is expensive).
Extra hardware required (hubs or switches) which adds to cost.
If a hub or switch fails all the devices connected to it will have no network connection.
