Question

What is Protocol ?

Answer 1

i searched on a website and it told, An agreed-upon format for transmitting data between two devices. The protocol determines the following:
•the type of error checking to be used
data compression method, if any
•how the sending device will indicate that it has finished sending a message
<<<what is meant by that ? >>>

Answer 2

A protocol is a set of rules defined by both parties or machines about how the data will be processed while sending/recieved.

Take for example TCP, you need both machines to agree on using TCP to be able to stablish a connection. If one is attempting to use UDP to transfer information, a connection cannot be stablished, since UDP is connection-less.

That's protocol for connections, however it can have different applications, but generally it means an agreement between two sides.

what is UDP ?

Answer 7

User Datagram Protocol, a connection-less protocol in which a machine sends a datagram and "doesn't care" if the other one recieves it, makes something called "best effort" to transmit it. But a connection is not stablished like TCP.
