A Local Area Network (LAN) is a network that connects computers and devices within a limited geographical area, such as a home, office, school, or business environment. It allows devices to communicate with each other and share resources and services.
By definition, a LAN connects devices in a single physical location. The network can range from a small home setup with two or more users to a large enterprise network containing thousands of devices and users.
The main characteristic of a LAN is that it connects devices within a restricted area. However, in some cases, a LAN can be extended between nearby buildings while still remaining within a specific organizational environment.
A LAN uses various networking components such as:
Network cables
Wireless access points
Switches
Routers
Other networking devices
These components help connect devices to internal and external services, including:
Web services
Internal business applications
File-sharing services
Cloud-based services
Communication systems
In homes and businesses, LANs enable efficient communication, resource sharing, internet access, and secure connectivity between multiple devices and users.
