A LAN (Local Area Network) is a network that connects computers and other devices within a limited area such as a home, office, school, or building. LANs are designed to enable resource sharing like files, printers, and internet access.
How LAN Works
Devices in a LAN are connected through network cables, Wi-Fi, or switches/routers. Each device is assigned a local IP address, and they communicate directly or via a central router. LANs are usually privately owned and managed.
Key Components of a LAN
Router: Connects LAN to the internet and assigns IP addresses.
Switch: Distributes network connection between multiple devices.
Access Point: Provides wireless connectivity within the LAN.
Ethernet Cables: Connect devices physically to the network.
Devices: Computers, printers, smart TVs, mobile phones, etc.
Types of LAN
Wired LAN: Uses Ethernet cables for fast, secure connections.
Wireless LAN (WLAN): Uses Wi-Fi to connect devices without physical cables.
Peer-to-Peer LAN: Devices share resources directly without a central server.
Client-Server LAN: A central server manages resources and security.
