What is the purpose of a network router in a computer network?

The purpose of a network router in a computer network is to connect multiple devices together and direct the flow of network traffic between them. It acts as a central hub that receives data packets from one device and determines the most appropriate path to send them to another device within the network. This allows the devices to communicate with each other and access the internet if connected. Routers also provide functionalities like network address translation (NAT), port forwarding, firewall protection, and quality of service (QoS) management, which help enhance the efficiency, security, and performance of the network.

The purpose of a network router in a computer network is to connect multiple devices or networks together and allow them to communicate with each other. It acts as a central hub or gateway that forwards data packets between different networks, such as a local area network (LAN) and the wider internet. Routers analyze the IP addresses of incoming data packets and determine the best path for forwarding them to their destination. Additionally, routers can perform essential network functions like network address translation (NAT), which allows multiple devices to share a single internet connection, and provide security by implementing firewalls and filtering incoming and outgoing traffic. Overall, routers play a vital role in directing data traffic and ensuring efficient and secure communication within a computer network.
