LAN

Definition:
A Local Area Network (LAN) is a network that connects computers and devices within a limited geographical area, such as a home, office, or school. It allows devices to communicate with each other, share resources, and exchange data.

Key Features:

1. Limited Range: Typically covers a small area, such as a building or campus, usually within a few kilometers.
2. High Speed: LANs offer fast data transfer rates, often up to 1 Gbps or more.
3. Low Cost: The setup and maintenance of LANs are generally inexpensive compared to larger networks like WANs.
4. Easy to Expand: New devices can be added to the network with minimal effort.

Core Components:

• Devices: Such as computers, printers, and storage devices.
• Switches: Used to connect devices within the network.
• Routers: Used to connect the LAN to other networks, such as the internet.
• Cabling: Ethernet cables or wireless connections (Wi-Fi).

Uses:

• File and printer sharing among devices.
• Internet access for all connected devices.
• Centralized management of resources and data in small environments.

Example:
In a small office with several computers, a LAN allows these computers to share files, access printers, and connect to the internet via a single router.

Summary:
A Local Area Network (LAN) is a small-scale network that enables devices within a specific location to connect and communicate efficiently, allowing for shared resources and fast data exchange.
