A protocol is a set of invisible compute rules that govern how an Internet document will be transmitted onto the screen. For two computers to communicate with one another, they must be able to understand one another through the same language. In order for computers to exchange information there must be a preexisting agreement as to how the information will be structured and how the sides will send and be received. The most important that defines the common networking protocols is the OSI known as Open Systems Interconnection. Introducing the TCP and the IP are two different protocols that are often linked together. The linking of several protocols is fairly common since the functions of different protocols may be complementary so that together they carry out particular tasks that are bases of operation layers. These suits of protocols are often used with many local area networks and carries out the basic operations of the Internet. Emailing also has its own set of protocols that has a variety of both for sending and receiving mail. The most common protocol for sending mail is the SMTP that is known for as Simple Mail Transfer Protocol. Then for receiving emails, the protocol being most commonly used is the Post Office Protocol, POP for short. Both the SMTP and the POP is used for managing the transmission for delivery of mail across the Internet.

Web pages that are constructed to a standard method are called Hypertext Markup Language known as HTMO. The HTMP page is transmitted over the Internet in a standard way with a formation known as Hyper Transfer Protocol otherwise known as HTTP. These protocols also use the TCP and IP is managed by the Web transmission. The File Transfer Protocol lives up to its name as FTP provides a method for copying files over a network from one computer to another. Generally it provides for some simple file management on the contents of a remote computer. In todays world it is primary used to upload files to share via the Internet that can also be used for downloading from it as well. The purpose of a protocol is a reference of ensuring that all programs are written following the same formats. Creating a program that could not be access wouldn’t be able to interact with any other and the output wouldn’t be accessible to site. For this reason whether it is proprietary or public must all programs follow the common standards of protocol.
