Internet Protocol Suite
The Internet Protocol Suite is a term used to describe the set of communication protocols, developed individually by the IT community, for sending data over computer networks such as the Internet. TCP (Transmission Control Protocol) and IP (Internet Protocol) were the first two protocols included in the Internet Protocol Suite and are the basis from which the term originated.
Sometimes referred to as TCP/IP, The Internet Protocol Suite as a whole consists of a number of internetworking protocols that operate in a ‘network layer’. Each of these layers are designed to solve a specific issue affecting the transmission of data. Higher layers are closer to the user and deal with more abstract data, relying on lower layers to convert data into forms that can be physically manipulated for transmission.
To elaborate, please refer to table (1a), which breaks down the layers included in TCP/IP suite and explains each layer’s function and possible protocols that can be used to fulfill these functions.
