Explain TCP/IP briefly.

The IP protocol deals only with packets, while TCP (Transmission Control Protocol) enables two hosts to establish a connection and exchange streams of data. TCP operates in conjunction with the Internet Protocol (IP), which defines how computers send packets of data to each other. These packets are initially delivered randomly, and TCP at the receiver side collects and arranges them in sequential order. IP is the primary protocol in the Internet layer of the Internet Protocol suite, responsible for delivering packets from the source host to the destination host based on the IP addresses mentioned in the packet headers, following the shortest route.
