Can you explain what the TCP/IP protocol is and its role in networks?

TCP/IP is a set of network protocols that enables data transmission over the internet and local networks. TCP (Transmission Control Protocol) is responsible for establishing connections, reliable delivery, and error checking, by breaking data into packets and reassembling them in the correct order. IP (Internet Protocol) handles addressing and routing of packets, determining how data reaches from the sender to the receiver.

The role of TCP/IP in networks is to provide a standardized way for devices to exchange data, regardless of their hardware or software. This protocol suite makes websites, email, file sharing, and other network services possible.
