What is TCP/IP?

TCP/IP (Transmission Control Protocol/Internet Protocol) is a suite of communication protocols used to interconnect network devices on the internet. It's a set of rules that govern how data is transmitted over a network, defining how data should be broken into packets, addressed, transmitted, routed, and received at the destination. It's the fundamental protocol suite for internet communications, providing end-to-end data communication specifying how applications should create channels of communication across a network. Common uses include web browsing, email, file transfer, and remote access.
