Transmission Control Protocol and the Internet Protocol (TCP/IP) is a conceptual model set of rules and procedures similar to the computer network.
The TCP/IP model was created in the 1970s by the Defense Research Project Agency(DARPA). Like the OSI model, it describes general guidelines for designing and implementing computer protocols.
TCP/IP layers
TCP/IP consists of four layers:
- Application
- Transport
- Internet
- Network Acces
