Router
USUK
A networking device that forwards data packets between computer networks, directing traffic on the internet.
Definition
A router is a networking device that receives, analyzes, and forwards data packets between computer networks. It operates at the network layer (Layer 3) of the OSI model and uses routing tables and protocols (such as OSPF, BGP, or RIP) to determine the best path for data to travel from source to destination. Home routers typically combine routing, switching, and wireless access point functionality, while enterprise routers handle complex traffic management across large networks.
Example
“Your home router receives data from your ISP and distributes it to all connected devices, whether via Ethernet cables or Wi-Fi.”
