What is LAN? Local Area Network

A local Location Network (LAN) is a collection of computers and other devices connected by Ethernet or Wi-Fi within a single, limited area, such as a building, office, or home.

  • A LAN is a network that is contained inside a small geographic area.  LANs examples are home Wi-Fi networks and small business networks.
  • The fault tolerance of a LAN is higher, and the network is less congested.
  • In general, the data transfer rate is high. They range in speed from 100 to 1000 Mbps.

Wired LANs and wireless LANs are the two main forms of LANs.

  1. A wired LAN connects servers and other network devices using switches and Ethernet cables.
  2. Wi-Fi is used to connect devices in a wireless LAN. Wi-Fi is a connection protocol that uses radio waves in the 2.4 GHz and 5 GHz frequencies to connect devices to a LAN.

 Two types of local area network architecture are

  1.  Client-Server: Multiple client devices are connected to a central server on a client-server LAN, which oversees application access, device access, file storage, and network traffic.
  2.  Peer-to-peer: There is no central server in a peer-to-peer LAN, and each device contributes equally to the network’s operation. Peer-to-peer LANs are usually smaller and can’t manage a lot of traffic.
