Understanding the Role of Routers: Gateways Enabling Communication Between IP Networks

Which device acts as a gateway to allow hosts to send traffic to remote IP networks?

The device that acts as a gateway to allow hosts to send traffic to remote IP networks is called a router.

A router is a networking device that is responsible for forwarding data packets between different networks.

It operates at the network layer (Layer 3) of the OSI model and uses routing tables to determine the best path for data packets to reach their destination.

When a host wants to send traffic to a remote IP network, it will send the data packets to its default gateway, which is typically the IP address of the router that connects the host to the local network.

The router will then examine the destination IP address of the data packets and consult its routing table to determine the next hop on the path towards the remote network.

It will forward the packets to the next hop router, which will repeat the process until the packets reach the destination network.

In this way, routers act as gateways or intermediaries that enable communication between hosts in different IP networks, allowing traffic to flow seamlessly across the internet.
