Abstract: Generally, small networks are often called as LAN (Local Area Network).A LAN is a network allowing easy access to the computers or peripherals. Networking means interconnection of computers. These computers can be linked together for different purposes and using a variety of different cabling types. Thus leading to less wastage of time and hence increased productivity.LAN mainly depends on the characteristics and the factors such as Topology, Medium Access Control (MAC) and Transmission Medium. This provides the security. LAN has Ethernet. LAN mainly works on the Carrier-Sense Multiple Access with Collision Detection (CSMA/CD). The Ethernet specification performs the same functions as the OSI physical and Data Link Layer of data communications. Wired LANs transmit the data but these are physically connected through repeaters and bridges and Wireless LANs transmit and receive data over air, without the use of any cable. These are physically not connected.
Keywords: LAN (Local Area Network), MAC (Medium Access Control), CSMA/CD (Collision-Sense Multiple Access with Collision Detection), FHSS (Frequency-Hopping Spread Spectrum technology), DSSS (Direct-Sequence Spread Spectrum Technology), AP (Access Point), NOS (Network Operating System).

Scope of the Article: Local Area Network
