Networking - Local Area Network

LAN (Local Area Network) 

1. Definition:
   A LAN (Local Area Network) is a network that connects computers and devices within a small area like a home, school, office, or building.

2. Limited Range:
   LAN typically covers a short distance—usually up to a few hundred meters.

3. Devices Connected:
   It connects computers, printers, routers, switches, and other devices to share resources.

4. High Speed:
   LANs offer high data transfer speeds, usually ranging from 100 Mbps to 10 Gbps.

5. Wired or Wireless:
   LAN can be wired (using Ethernet cables) or wireless (Wi-Fi).

6. Resource Sharing:
   Users on a LAN can share files, printers, internet access, and other resources easily.

7. Private Ownership:
   A LAN is usually owned and managed by a single person or organization (e.g., a company or a school).

8. Low Cost:
   Setting up and maintaining a LAN is relatively inexpensive compared to wide-area networks.

9. Security:
   LANs are more secure than public networks because access is limited to trusted users/devices.

10. Common Use:
    LANs are commonly used in homes, computer labs, offices, libraries, and schools for daily connectivity and collaboration.
