What is Protocol?
Protocols
A
communication protocol is (Networking protocol) is a system of digital message
formats and rules for exchanging messages in or between computing system and in
telecommunications. A protocol may have a formal description. Protocol may include
signaling, authentication and error detection and correction capability.
In
a routing protocol, it specifies that how routers communicate with each other
and with the other types of machines. Protocols are determines and enable the
routes between the nodes on a computer network. Algorithms determine the
specific choice of routing. A router has knowledge only the direct attached
networks and a protocol shares information about the neighbors immediate and
then throughout the network. A router can understand the network topology
through the protocol. So we can say that a protocol is playing very important
role in a network. Although, there are many types of protocols.
