What is Network Gateway?
A gateway is a network node used in telecommunications that connects two networks with different transmission protocols together. Gateways serve as an entry and exit point for a network as all data must pass through or communicate with the gateway prior to being routed.
What is Network Gateway example?
On an Internet Protocol (IP) network, IP packets with a destination outside a given subnet mask are sent to the network gateway. For example, if a private network has a base IPv4 address of 192.168. 255.0, then any data addressed to an IP address outside of 192.168. 1.0 is sent to the network gateway.
What is the difference between a router and a gateway?
A router is a device that is capable of sending and receiving data packets between computer networks, also creating an overlay network. A Gateway, on the other hand, joins dissimilar systems. Gateway it is defined as a network entity that allows a network to interface with another network with different protocols.
What is the role of a gateway in computer network?
A Gateway is a network point that acts as an entrance to another network using different protocols. It is a shared connection between a local area network and a larger system i.e. WAN. It basically works as the messenger agent that takes data from one system, interprets it and transfers it to another system.
