__ manages the assembling of a message or file into smaller packets that are transmitted over the Internet and then received by a TCP layer on the destination computer that reassembles the packets into the original message. a. Internet control protocol b. Internet Manager c. Network control protocol d Transmission control protocol

The correct answer is d. Transmission Control Protocol (TCP).<br /><br />TCP is a transport-layer protocol that manages the assembling of a message or file into smaller packets that are transmitted over the Internet. These packets are then received by a TCP layer on the destination computer, which reassembles the packets into the original message or file. TCP ensures that the packets are delivered in the correct order and without errors, providing reliable and efficient communication over the network.
