Detailed explanation-1: -A network protocol is an established set of rules that determine how data is transmitted between different devices in the same network. Essentially, it allows connected devices to communicate with each other, regardless of any differences in their internal processes, structure or design.
Detailed explanation-2: -The most important protocols for data transmission across the Internet are TCP (Transmission Control Protocol) and IP (Internet Protocol). Using these jointly (TCP/IP), we can link devices that access the network; some other communication protocols associated with the Internet are POP, SMTP and HTTP.
Detailed explanation-3: -A communication protocol is a system of rules that allows two or more entities of a communications system to transmit information via any kind of variation of a physical quantity. The protocol defines the rules, syntax, semantics and synchronization of communication and possible error recovery methods.
Detailed explanation-4: -The correct answer is A protocol. A protocol is a set of rules that governs the communications between computers on a network.
Detailed explanation-5: -A protocol is a set of rules and guidelines for communicating data. Rules are defined for each step and process during communication between two or more computers. Networks have to follow these rules to successfully transmit data.
