LAN

A Local Area Network (LAN) is a network that connects computers and devices within a limited area, such as a home, office, or school. LANs allow connected devices to share resources, like files, printers, and internet connections, providing high-speed, low-latency communication.

Key Features of LANs:

  1. High Speed: LANs typically offer fast data transfer speeds (often 1 Gbps or more) due to the short distances between connected devices.
  2. Limited Range: LANs are designed for small, localized areas, typically using Ethernet cables or Wi-Fi to connect devices within a building or campus.
  3. Centralized Resource Sharing: With LANs, users can share files, applications, and peripheral devices (like printers), reducing the need for duplicate resources.
  4. Enhanced Security and Control: LANs allow network administrators to manage security, permissions, and access, limiting network access to authorized users only.

Common Components of a LAN:

  • Router: Connects the LAN to the internet and manages traffic.
  • Switch: Connects devices within the LAN and directs traffic between them.
  • Access Points: Provide wireless connectivity within the LAN for mobile devices.

Advantages of LANs: LANs enable efficient communication, resource sharing, and centralized management, ideal for small businesses, schools, and homes. They are cost-effective and relatively easy to set up and maintain.

In summary, LANs connect devices in a confined area, supporting high-speed data transfer, resource sharing, and simplified network management within homes and businesses.
