What does TCP/IP stand for?

TCP/IP stands for Transmission Control Protocol/Internet Protocol. This is a fundamental set of communication protocols used for the internet and similar networks. The protocol originally developed by the U.S. Department of Defense allows different types of networks to communicate with each other, forming the basis for the internet as we know it today.

Transmission Control Protocol is responsible for ensuring that data is sent and received accurately through a connection-oriented communication process, while the Internet Protocol is responsible for addressing and routing packets of data so they reach their intended destination across network boundaries. The combination of these two protocols facilitates robust and reliable data transmission.

The phrasing in the other options either misinterprets or incorrectly names the components or functions of the TCP/IP suite, which is why they do not accurately describe what TCP/IP stands for. This understanding is crucial in the field of networking and helps establish a clear foundation for how data moves across various systems within the global network.
