In this article we will discuss Local Area Network, will make brief discussion on Local Area Network, In last article we discuss about Metropolitan Area Network (MAN).
A computer network that links devices within a building or group of adjacent buildings, especially one with a radius of less than 1 km.
A local area network is a computer network that interconnects computers within a limited area such as a residence, school, laboratory, university campus or office building. By contrast, a wide area network not only covers a larger geographic distance, but also generally involves leased telecommunication circuits.
A local area network may serve as few as two or three users (for example, in a small-office network) or several hundred users in a larger office. LAN networkingcomprises cables, switches, routers and other components that let users connect to internal servers, websites and other LANs via wide area networks.
Local area networks (LANs) are computer networks ranging in size from a few computers in a single office to hundreds or even thousands of devices spread across several buildings. They function to link computers together and provide shared access to printers, file servers, and other services.
