TCP/IP is two separate internet protocols that work in conjunction to ensure data is transferred securely across the network.
TCP stands for Transmission Control Protocol. This is a communication standard that enables devices to transmit messages. The protocol makes sure that packets are securely sent & received across that network.
IP stands for Internet Protocol. Since every device that connects to the internet has to be assigned an IP address, this protocol defines how devices and other applications transmit or exchange these packets of information/ data. (What Is TCP/IP in Networking? | Fortinet, n.d.)
