Internet Protocols Questions
A gateway is a network node that serves as an entrance or exit point for data traffic between different networks. It is responsible for translating protocols, performing network address translation (NAT), and providing security features such as firewall protection.
On the other hand, a router is a device that forwards data packets between computer networks. It determines the best path for data transmission based on the destination IP address in the packet header. Routers operate at the network layer (Layer 3) of the OSI model and are primarily used to connect multiple networks together.
In summary, the main difference between a gateway and a router is their functionality. A gateway is a more comprehensive network device that performs protocol translation and security functions, while a router focuses on forwarding data packets between networks based on IP addresses.
