Local Area Network, commonly referred to as LAN, is a collection of computers that are connected together in a relatively small geographical area, usually within a single building or campus. The computers are connected together using either a wired or wireless network. The network allows computers to both access the same resources, as well as share files and communicate with each other.
Typically, a Local Area Network will consist of a router, which serves as the connection point, as well as any additional computer hardware necessary. This can include switches, hubs, repeaters, cables, and other networking equipment. A LAN is typically segmented into multiple local networks to ensure its performance and security.
LANs are used in both home and business environments. In a home setting, a Local Area Network is often used to allow the computers to share access to the internet, or allow the computers to quickly share data between themselves. In a business setting, a LAN can be used to allow multiple users to access shared resources, such as a printer or network storage devices, and to ensure secure communication between the computers on the network.
The speed and throughput of a LAN depend on the technology used for connecting the computers on the network. The most common network technologies are Ethernet, Wi-fi, or Powerline. Each of these technologies has distinct advantages and disadvantages, and should be carefully evaluated to ensure the best possible performance and security.
