What is a LAN?
A LAN is a network that connects devices within a limited geographical area—such as an office, industrial hall, or technical facility—for internal communication and resource sharing.
How does a LAN work?
A LAN consists of one or more network segments built using switches, access points, and cabling or wireless communication (WiFi). Routers are often used as gateways to external networks.
Common LAN Components:
- Switches: Distribute data internally
- Access points: Provide wireless access
- Routers: Connect to the internet and route traffic between networks
- Ethernet cables: Provide stable, wired transmission
Examples of LAN Usage:
- Sharing common resources such as printers and storage
- Internal system communication for business-critical applications
- Integration with external networks via firewalls and WAN solutions
