Explain what is meant by the term ‘TCP/IP stack’ [3]

The TCP/IP stack is the Transmission Control Protocol / Internet Protocol. (1)A Protocol is a set of rules (1) the outline the ways in which data should be set out to make sure it can be understood. Both the sender and receiver use the protocol. (1)The TCP/IP stack is a set of different protocols built up in layers (1), with each layer setting out how communication works at a each level of abstraction.The layers are  Application, Transport, Internet, Link. (1)When the data is encapsulated in further layers from the stack the Protocols from that layer must be applied to the data. (1)
