LAN stands for Local Area Network. It refers to networks with limited spatial extension. LANs are usually used in private or business premises to configure home or business networks. It supports communication between different devices and the exchange of data.
LAN consists of at least two terminals but can also connect several thousand devices. LAN can connect computers, smartphones, printers, scanners, storage devices, servers, and other network devices to each other and connect them to the Internet. However, if wider spatial distances must be covered, MAN and WAN networks are more suitable.
By now, most LANs are made via Ethernet cables. An Ethernet LAN can be divided into several virtual (VLAN) or physical LANs. Switches and routers are used to structure Local Area Networks. As an interface, the hardware controls the connections between individual network users and ensures that data patches reach their destination.
