LAN

LAN Abbreviation for local area network; It is a computer network that connects computers and vehicles in a limited geographical area such as home, school, laboratory, business buildings.

The features of LANs are that unlike WANs (Wide area networks), higher data transfer, smaller area, and no need for an intermediate staff (English: Leased telecommunication lines) for monthly rental to ensure permanent connection.

ARCNET, Token Ring and other technological applications were used in the past, but today, ethernet and wireless internet have become widespread with the presence of wiring (in English, twisted pair) that prevents electromagnetic interference.

 In a typical home or small office LAN, a modem provides internet connectivity, a router that allows other devices to share and connect with each other, and a Wi-Fi access point that allows devices to access the network wirelessly. Sometimes these functions are combined in a single device.

For example, many ISPs provide a junction unit that acts as a modem, router, and wireless access point. Sometimes you can also find devices called switches that allow you to split a single Ethernet connection into multiple ports.

On larger LANs, you can often find the same type of network equipment on a much larger scale, depending on how many devices are used and how powerful they are.

Professional routers and switches, for example, can serve many more simultaneous connections than home counterparts, offer more robust security and monitoring options, and provide good customization. Professional-grade Wi-Fi access points often allow multiple devices to be managed from a single interface and provide better access control.
