Networks
Computer networks have been used in libraries to link workstations in remote branches to centralized systems, allowing multiple sites to share facilities such as CD-ROM / DVD drives and printers. Networks are also used to access external services.
Intranet
Usually all information and digital information is saved on to a central database or server. Computers in different parts of the libraries could be attached to it through cables or wireless. These individual computers are known as clients and the main computer is known as Server. This setup is known as Local area network (LAN).
Internet
The central server could be connected to Internet through a gateway. Readers can access internet on their individual computers through the server. Librarian can control the websites which are viewed and restrict the website which they don’t want to be accessed in the libraries.
