TCP/IP

USUK

Transmission Control Protocol/Internet Protocol — the foundational communication protocols of the internet.

Also: TCP/IP stack · Internet protocol suite

Definition

TCP/IP is a suite of communication protocols used to interconnect network devices on the internet. TCP (Transmission Control Protocol) handles the reliable, ordered, and error-checked delivery of data packets between applications, while IP (Internet Protocol) handles the addressing and routing of those packets. Together, they form the backbone of internet communication, operating across four abstraction layers: network access, internet, transport, and application.

Example

When you download a file, TCP/IP ensures every packet arrives correctly and in order, retransmitting any lost packets automatically.
