WJEC A2 ICT - NETWORKS

Which of these is not an advantage of peer to peer compared to client server?

• You need a network manager
• It is relatively easy to set up
• Lower operating costs - less set-up and maintenance costs.
• No reliance on a server

Which of these is not an advantage of a client server network compared to peer to peer?

• Back ups can be done centrally
• Load tolerant - suitable for large networks
• Centrally stored files are easier to find
• If server breaks down the network is unusable

Which of these is not an advantage of wifi?

• It's suitable for listed buildings were holes can't be drilled for wires
• Transmission speed faster than cable

• Health and safety improved as no trailing cables
• Gives the freedom of working anywhere a signal can be received

Which of these is not a disadvantage of wifi?

• There may be security problems, even when encryption is used
• Transmission speed slower than cable
• Power consumption is high (meaning laptop batteries quickly drained)
• Global set of standards - you can use wifi all over the world

Which of these is not an advantage of a star topology compared to a ring?

• Load tolerant - can add extra computers without affecting performance
• Fault tolerant - if one computer goes down the network can still be used
• Faster transmission speeds possible as the data travels in one direction
• Easy to add extra computers - don't need to bring down the network to do so

Which of these is not an advantage of a ring network?

• Computers are not dependent on a central computer
• Faster transmission speeds possible as data travels in one direction
• Each computer has same access so no computer can hog the network
• If there is a break in the network the whole network fails

Which of these tasks is NOT one that would be performed remotely by a network manager?

• Check to see right number of licences.
• Manage passwords
• Guide users through problems
• Log off users that have forgotten to do so

Which of these tasks would NOT be done by the network manager using remote management?

• Sending instant messages
• Clear printer queues remotely
• Create new user account
• Check on hardware that's failing

If an organisation is getting a new network they will need to think about existing systems to integrate.  Which of the below would NOT be a reason for this?

• Less maintenance
• More often networks are not developed from scratch but need to fit in with existing systems
• It must support any peripherals already in use, e.g. bar code readers, printers, etc
• They will want the system to fit in with existing pcs to save money where possible
