Router
Router
A network device that directs data traffic when connecting to the internet.
In Simple Terms
A router is a device that connects the internet to the computers and smartphones in your home, delivering data to the right destination. It's used when you want to connect multiple devices to the internet at the same time. It figures out which device—like a smartphone or computer—incoming data from the internet is meant for, and directs it accordingly.
Behind the Name
The word "router" comes from "route" (a path or way) plus the suffix "-er," meaning "something that does" an action. It got this name from its role in guiding data on the internet along the right path to reach its destination.
Take a Closer Look!
A router is a network device that connects different networks together and directs data to the right destination.
It acts as a bridge between the internet—a massive network—and the private network in your home or school.
Put simply, it works like a post office or a traffic officer for data.
Without a router, data arriving from the internet wouldn't know which smartphone or computer in your home it's meant for.
The router sorts each piece of data correctly, as if saying, "This one's for Dad's computer" or "This one's for Sis's phone."
In many homes, a "Wi-Fi router"—one with an antenna that lets you connect wirelessly—is widely used.
This lets you connect many devices to the internet at the same time without plugging in any cables.
