A router is a networking device that directs data packets between computer networks. It connects multiple networks, such as a local area network (LAN) and the internet, ensuring that data reaches its intended destination efficiently. Routers use IP addresses to determine the best path for forwarding data.
Key Functions of a Router:
Traffic Management: Routes data between devices and networks.
IP Address Assignment: Uses DHCP to assign IP addresses to connected devices.
Network Security: Includes firewall and security features to protect against threats.
Wireless Connectivity: Many routers provide Wi-Fi for wireless devices.
