What is Information Network Computer Network? Routing is performed for many kinds of networks, including circuit switching networks and packet switched networks. Network bridges and network switches are distinct from a hub in that they only forward frames to the ports involved in the communication whereas a hub forwards to all ports. Bridges only have two ports but a switch can be thought of as a multi-port bridge. Switches normally have numerous ports, facilitating a star topology for devices, and for cascading additional switches. National Information Network Each layer performs a specific function network communication. Gateway is a device that connects two or more networks with different types of protocols. Two different types of networks require a gateway to communicate with each other. For example, the computer on a LAN require gateway to access the internet. These are the standards which have been properly approved by networks governing body. These are developed with proper...
