hi Sonakshi A network gateway is an internetworking system capable of joining together two networks that use different base protocols. A network gateway can be implemented completely in software completely in hardware or as a combination of both. Depending on the types of protocols they support network gateways can operate at any level of the OSI model. Because a network gateway by definition appears at the edge of a network related capabilities like firewalls tend to be integrated with it. On home networks a broadband router typically serves as the network gateway although ordinary computers can also be configured to perform equivalent functions if you dont use Gateway. Thanks Pravin.
