Networks

1. Advantages of networks

   • Hardware (peripheral devices) can be shared
   • software can be shared
   • data can be shared
   • networked computers can communicate
   • networked computers can be centrally controlled by a network manager
   • files stored on a server allow for easier back-up schedules than if the files were stored on multiple computers

2. disadvantages of networks

   • the cost of cabling and setting up can be high
   • a virus can spread through a network very quickly
   • hackers may gain unauthorised access to files saved on a network server
   • networks can fail to work properly - causing a loss of access to data, hardware and software
