Router
A network router is a device that connects multiple devices in a network and directs internet traffic between them. Think of it as a traffic controller—it makes sure data gets to the right device. Routers are a key part of modern home and business networks, allowing computers, smartphones, and smart devices to share the same internet connection.
Functions of a Router in a Network
- Directs Traffic: The router ensures that the data you request (like streaming a video or loading a website) reaches your device and not someone else's.
- Manages Devices: It assigns each device in your network a unique address (called an IP address) to avoid confusion.
- Provides Security: Most routers include a firewall to block unauthorized access to your network.
