LAN

A LAN (Local Area Network) is a computer network that covers a small geographic area, typically a building, office, or campus. LANs are used to connect devices, such as computers, printers, and servers, to share resources and communicate with each other.

Here are some key characteristics of LANs:

Size: LANs are designed to cover a small geographic area, typically a single building or campus.

Ownership: LANs are usually owned and managed by a single organization, such as a company, school, or government agency.

Topology: LANs can use different network topologies, such as a bus, ring, star, or mesh.

Connectivity: LANs can be connected using different technologies, such as Ethernet, Wi-Fi, or Token Ring.

Speed: LANs can provide high-speed communication between devices, with speeds ranging from 10 Mbps to 10 Gbps or more.

Security: LANs can be secured using different technologies, such as firewalls, VPNs, and encryption, to protect against unauthorized access and data breaches.

Some common applications of LANs include file sharing, printer sharing, email, and access to the Internet. LANs are also used in many industries, such as education, healthcare, manufacturing, and finance, to support critical business functions and improve productivity.
