To answer this question, we must first understand what computer networks are. At the basic level, a network is two or more computers connected together for the purposes of sharing resources, such as software or files, and to facilitate communication between individuals. Even to this day, there is no one in charge of the Internet.
Communication is smoother, for example, when people talk one at a time.
Questions are asked by one party, and answered by the listener. Computers as well need such protocols while communicating or exchanging data with one another. Standard protocols on any computer network support this exchange. Computer protocols can be a series of programs, routines, or sub-routines shared by two or more computers. The Internet could not work without protocols.
