Communications Protocol
Hardware and software standards that govern data transmission between computers. The term "protocol" is very generic and is used for hundreds of different communications methods. A protocol may define the packet structure of the data transmitted or the control commands that manage the session, or both. A protocol suite such as TCP/IP is made up of several levels of functionality. Learning the 7-layer protocol hierarchy, known as the "OSI model," is essential for understanding protocols. See OSI model and interface.
TCP/IP is the standard communications protocol of the Internet and most internal networks. Ethernet is the local network standard. TCP/IP is responsible for routing packets and ensuring that everything sent was received. Ethernet is an access method that is responsible for moving packets from one node to another. See TCP/IP, Ethernet, Token Ring, ATM, IPX, SPX, NetBIOS, NetBEUI and SS7.
