accessing a client network server

 This allows users to:
o Access centrally saved files and folders
o Save files to a central location without using space on the computer

Peer to peer servers are used when computers are connected together without using a
central large file server. Each computer stores its own files but can be shared across the
network.

 No pressure on one server to store data
o Disadvantages
 No centralised control on security
 Some machines may slow the network down
 Each computer needs to be backed up
