Networks

Networks

1. Advantages

   • They allow groups of users to share and exchange information very easily. This allows greater productivity, as well as bringing people and data together.
   • Centralized databases are made possible by networks. If a single master copy of data is maintained on a central server, then all those who work with it will have access to the latest correct version of the data.
     • Server: A program that awaits and fulfills requests from client programs in the same or different computers.
   • They allow users to share peripherals, such as printers. This saves money on buying lots of individual peripherals for each user.
   • Updating software on all devices connected to the network is much easier.

2. Disadvantages

   • Networks are expensive. Purchasing network cabling and file servers is costly, as well as hiring technicians to maintain and update the network.
   • If a file server breaks down, the files stored on it become inaccessible, so all users on the network will be unable to access the files.
   • If a virus is present on the network, it can spread to all devices connected to it, which may cause large amounts of data to be lost.
