Across
- 7. network made up of a combination of other network topologies.
- 9. method of data storage where data is stored on off-site servers.
- 10. network in which each node can share its files with all the other nodes. Each node has its own data and there is no central server.
- 11. – network that uses separate dedicated servers and specific client workstations. All client computers are connected to the dedicated servers.
- 14. network which is larger than a LAN but smaller than a WAN, which can cover several buildings in a single city, such as a university campus.
- 21. wireless LAN.
- 22. network that is centred around a person or their workspace.
- 23. a server on a network where central files and other data are stored. They can be accessed by a user logged onto the network.
- 25. device that needs access to the internet for it to work and depends on a more powerful computer for processing.
- 26. network covering a very large geographical area.
Down
- 1. cable made up of central copper core, insulation, copper mesh and outer insulation.
- 2. device that connects LANs which use the same protocols.
- 3. hardware used to connect together a number of devices to form a LAN that directs incoming data packets to all devices on the network (LAN).
- 4. hardware used to connect together a number of devices to form a LAN that directs incoming data packets to a specific destination address only.
- 5. modulator demodulator. A device that converts digital data to analogue data (to be sent down a telephone wire); conversely it also converts analogue data to digital data (which a computer can process).
- 6. type of cable in which two wires of a single circuit are twisted together. Several twisted pairs make up a single cable.
- 8. device used to boost a signal on both wired and wireless networks.
- 12. device connected to a network (it can be a computer, storage device or peripheral device).
- 13. device that connects LANs which use different protocols.
- 15. network covering a small area such as a single building.
- 16. . These cards allow devices to connect to a network/internet (usually associated with a MAC address set at the factory.
- 17. wireless connectivity that uses radio waves, microwaves. Implements IEEE 802.11 protocols.
- 18. device which enables data packets to be routed between different networks (for example, can join LANs to form a WAN).
- 19. situation in which the same data is stored on several servers in case of maintenance or repair.
- 20. wireless connectivity that uses radio waves in the 2.45GHz frequency band.
- 24. client device which can work both off line and on line and is able to do some processing even if not connected to a network/internet.
