A local area network (LAN) refers to a computer network that spans a small area, typically within a single building, office, or campus. It is designed to connect computers and devices in close proximity to each other in order to enable data sharing, resource sharing, communication, and collaboration among users within that specific area.
A LAN typically consists of several interconnected devices, such as computers, printers, servers, switches, and routers, which are connected through a combination of wired and wireless networking technologies. The physical medium used for connections in a LAN can be Ethernet cables, fiber optic cables, or wireless signals.
The main purpose of a LAN is to facilitate communication and enable the sharing of resources, such as files, folders, printers, and internet access, among the connected devices and users. It allows for efficient and quick transfer of data between devices, enabling users to work collaboratively, share information, and access common resources.
LANs are commonly used in homes, offices, schools, and small to medium-sized enterprises (SMEs) where users need to share resources and communicate with each other within a confined area. LANs provide a cost-effective and efficient solution for connecting devices within close proximity, allowing for increased productivity, improved connectivity, and streamlined operations.
