Kontributor: Krisna Try Prasetyo What is LANA local area network (LAN) is a group of computers and associated devices that share a common communications line or wireless link to a server. Typically, a LAN encompasses computers and peripherals connected to a server within a distinct geographic area such as an office or a commercial establishment. Computers and other mobile devices use a LAN connection to share resources such as a printer or network storage. 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 networking comprises cables, switches, routers and other components that let users connect to internal servers, websites and other LANs via wide area networks. Ethernet and Wi-Fi are the two primary ways to enable LAN connections. Ethernet is a specification that enables computers to communicate with each other. Wi-Fi uses radio waves to connect computers to the LAN. Other LAN technologies, including Token Ring, Fiber Distributed Data Interface and ARCNET, have lost favor as Ethernet and Wi-Fi speeds have increased. The rise of virtualization has fueled the development of virtual LANs, which allows network administrators to logically group network nodes and partition their networks without the need for major infrastructure changes. Typically, a suite of application programs can be kept on the LAN server. Users who need an application frequently can download it once and then run it from their local device. Users can order printing and other services as needed through applications run on the LAN server. A user can share files with others stored on the LAN server; read and write access is maintained by a network administrator. A LAN server may also be used as a web server if safeguards are taken to secure internal applications and data from outside access. In some situations, a wireless LAN, or Wi-Fi, may be preferable to a wired LAN connection because of its flexibility and cost. Companies are assessing WLANs as primary means of connectivity as the number of smartphones, tablets and other mobile devices proliferates. Local Are Network (LAN) ComponentA Local Area Networks connects computers together to exchange data. Apart from the computers, and other devices like printers and faxes, a LAN has to have six essential components to function.
LAN has the following characteristics:
Functions of Local Area Network (LAN)LAN’s main function is to provide
resource sharing and mutual communication, which provides the following main services:
Applications of Local Area Network (LAN)The variety of applications for LANs is wide. To provide some insight into the types of requirements that LANs are intended to meet, the following sections discuss some of the most important general application areas for these networks.
What is LAN MAN and WAN?LAN stands for local area network. MAN stands for metropolitan area network. WAN stands for wide area network. Geographic Span. Operates in small areas such as the same building or campus.
What type of computer network connects computers and device in a limited geographical area such as a home, school computer laboratory office building?A local area network (LAN) is a computer network that interconnects computers within a limited area such as a residence, school, laboratory, university campus or office building.
What does a computer network called which covers a geographical area within a city?Metropolitan Area Network (MAN) –
It connects two or more computers that are apart but reside in the same or different cities. It covers a large geographical area and may serve as an ISP (Internet Service Provider).
In which network are computers located in the same geographic area?A Local Area Network (LAN) is a group of computer and peripheral devices which are connected in a limited area such as school, laboratory, home, and office building.
