FUNDAMENTALS OF COMPUTER

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: -protocol, in computer science, a set of rules or procedures for transmitting data between electronic devices, such as computers. In order for computers to exchange information, there must be a preexisting agreement as to how the information will be structured and how each side will send and receive it.

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: -Transmission Control Protocol (TCP) Internet Protocol (IP) User Datagram Protocol (UDP) Post office Protocol (POP)

Detailed explanation-5: -Communication protocols include basic data communication tools like TCP/IP and HTTP. Management protocols maintain and govern the network through protocols such as ICMP and SNMP. Security protocols include HTTPS, SFTP, and SSL.
