Communication Protocol

A communication protocol is a system of rules that allow two or more entities of a communications system to transmit information via any kind of variation of a physical quantity. These are the rules or standard that defines the syntax, semantics and synchronization of communication and possible error recovery methods. Protocols may be implemented by hardware, software, or a combination of both.

Type of Communication Protocol

• TCP/IP

           The Internet protocol suite is the computer networking model and set of 

           communications protocols used on the Internet and similar computer networks.
           It is commonly known as TCP/IP, because its most important protocols, the
           Transmission Control Protocol (TCP) and the Internet Protocol (IP) were the
           first networking protocols defined during its development.

• SMTP

           Simple Mail Transfer Protocol (SMTP) is an Internet standard for electronic
           mail (email) transmission. First defined by RFC 821in 1982, it was last updated
           in 2008 with the Extended SMTP additions by RFC 532 which is the protocol
           in widespread use today.

• AppleTalk

          AppleTalk was a proprietary suite of networking protocols developed by Apple
          Inc. for their Macintosh computers. AppleTalk includes a number of features
          that allow local area networks to be connected with no prior setup or the need
          for a centralized router or server of any sort. Connected AppleTalk-equipped
          systems automatically assign addresses, update the distributed namespace, and
          configure any required inter-networking routing. It is a plug-n-play system.
