C. To establish a common standard for sending messages between devices on the Internet.
The purpose of the Transmission Control Protocol (TCP) and Internet Protocol (IP) is to establish a common standard for sending messages or data packets between devices on the Internet. TCP ensures reliable and ordered delivery of data packets, handling error detection, flow control, and congestion control. IP, on the other hand, is responsible for the addressing and routing of data packets across networks.
Together, TCP and IP form the foundation of the Internet Protocol Suite (TCP/IP) and enable communication between devices over the Internet by providing a standardized set of rules and protocols for data transmission.
