LAN

Local Area Network

A network that connects computers and devices within a limited area, like a single building.

In Simple Terms

A LAN is a network that connects computers, smartphones, printers, and other devices within the same building, such as a home, school, or office. It's the technology at work when you connect your smartphone to a home Wi-Fi router to browse the internet, or send a print job from a computer to a printer. In short, it's used any time devices need to exchange information within a small, shared space.

Behind the Name

LAN stands for Local Area Network. "Local" means nearby or specific to a particular area, "Area" means a place or region, and "Network" means a connected system, or a web of links. Put together, the name describes a network that connects things within a small, nearby space.

Take a Closer Look!

A LAN is a computer network limited to a single building or site, like a home or an office.
While the internet is a massive network that connects the entire world, a LAN plays the role of connecting devices only within one specific, narrow space.
It's used to connect devices such as computers, smartphones, and game consoles within a nearby room or building so they can exchange information with each other.

Simply put, a LAN is a technology for creating your own private network space.
Thanks to it, multiple family members can share a single internet connection, or photos taken on a smartphone can easily be sent to and saved on another computer.
Devices on the same network can also exchange large amounts of data with each other quickly.

Broadly speaking, there are two ways to connect: wired and wireless.
A wired LAN, where devices are connected by plugging in cables, offers very stable communication that isn't disrupted by obstacles like walls.
A wireless LAN, best represented by Wi-Fi, uses radio waves instead, so there's no cable getting in the way, letting you connect freely from anywhere.
