A protocol is a set of rules describing some behavior. In order to communicate in a common manner, the sender and receiver have to agree on the "language" of communication.
A protocol states what those rules are, and because they are a standard, everyone agrees and knows what to expect.
Protocols r used for network devices to communicate to each other. For e.g if one device on a network needs IP address, it'll use respective protocols for that. For sending data over some media, protocols are used. For setting up the speed, protocols are required. For security, protocols are there.
Network is a world quite different form our human world. For what purpose we use our language, network devices use protocols for that.
what are protocols? why arethey introduced in network communications?
No
-Programmed services and protocols that move the messages across the network -Technologies that support network communications
These are called protocols - a standard set of rules for common communications across networks.
Session Layer
Network protocols provide mechanisms that enables communications between sysytems, clients, servers, websites etc. without protocola systems would not be able to communicate, share data etc.
protocols used for network device.
Routed protocols are the best paths in a network along which to send network traffic.
Saskatchewan Communications Network was created in 1991.
IPv4 and IPv6 are two different protocols . The two protocols are not compatible with each other. But they can exist in a same network together.No, those are two different protocols. However, they can co-exist in the same network (this is known as "dual stack").No, those are two different protocols.
