Lan Defined Local Area Network Computer Science Essay
The NIC allows the PC to connect to a network. It encrypts the data to be transmitted, according to the rules for the physical medium being used: a cable system or another medium. When the medium is shared, the NIC ensures that only one computer is transmitting data at a time. A local area network, LAN, is a group of these computers limited to a small geographic area, usually a single building. Setting up a LAN requires computers with network adapters, central connecting devices to connect these computers, and a numbering scheme such as IP addresses to differentiate. Quick Definition: A Local Area Network, LAN, is a network of interconnected computers, devices, and resources within a limited area, such as a home, office, or campus.LANs facilitate communication and resource sharing between connected devices such as printers, computers and scanners. Almost all aspects of networking are: Advantages and Disadvantages of a LAN Now let's discuss some major advantages and disadvantages of using a local area network. Benefits Sharing resources: A local area network makes it possible to share resources, such as printers, DVD drives, and hard drives, among interconnected computers. All resources, users, and computers in one area can communicate with users and computers in other locations through a WAN, consisting of two or more interconnected Local Area Networks or Metropolitan Area Networks. Computers in a Wide Area Network are connected to each other via public networks such as telephone lines, satellite connections or leased lines.
