Final answer:
TCP is a connection-oriented protocol that provides a process-to-process communication, and a process is identified by a unique combination of IP address and port number.
Step-by-step explanation:
The subject of this question is Computers and Technology and it is of High School level.
Out of the given statements, the statement 'd. A process is only identified by the IP address of the sending computer' is not true about TCP.
TCP, or Transmission Control Protocol, is a connection-oriented protocol, meaning it establishes a reliable connection between two devices before transmitting data. TCP segment sizes are allowed to vary based on the network conditions, but the protocol ensures that all segments are received correctly. TCP provides a process-to-process communication, where each process is identified by a unique combination of IP address and port number.
