which one of these is a advantage of a network

• Users can communicate with each other using electronic messaging

• Extra hardware is needed to create a network e.g. a switch

• Computers viruses can spread more rapidly

• If you are sharing an internet connection on the network, other people may use all the bandwidth.

which one of these is a disadvantage of a network

• Backup and version history of files is usually kept automatically.

• Collaboration on files is easy.

• Monthly/annual cost.

• Incompatibility between storage and applications.

which one of these is a correct description of a Lan

• stands for local area network. This is a collection of computers over a small geographical area

• stands for wide area network. A WAN is a network of computers over a large geographical area that makes use of external connections (telephone line)
