Networking

Yet another useful purpose for computer communications is the linking of computers together within a single office or office building; this is known as networking. Networking requires two main components: special network hardware and network software. Together, the parts of this system are known as a Local Area Network (LAN).

Networks are useful for sharing data, storing large amounts of information, and sharing expensive equipment such as laser printers. With a network, you can run multi-user programs such as database and order-entry and accounting systems. Each worker in the office using a computer connected to the network can add or retrieve information or share common peripherals such as the printer or hard drive.
