FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -TCP (Transmission Control Protocol) guarantees reliable data transmission by keeping track of which packets have been received successfully, resending any that have been lost or damaged, and specifying the order for reassembling the data on the other end. TCP/IP is a pair of protocols that provide an abstraction.

Detailed explanation-2: -Which of the following Internet protocols is MOST important in reassembling packets and requesting missing packets to form complete messages? Transmission Control Protocol (TCP).

Detailed explanation-3: -The correct answer is TCP. The Transmission Control Protocol (TCP) guarantees reliable transmission by breaking messages into packets, keeping track of which packets have been received successfully, resending any that have been lost, and specifying the order for reassembling the data on the other end.

Detailed explanation-4: -The Transmission Control Protocol (TCP) is a transport protocol that is used on top of IP to ensure reliable transmission of packets. TCP includes mechanisms to solve many of the problems that arise from packet-based messaging, such as lost packets, out of order packets, duplicate packets, and corrupted packets.

Detailed explanation-5: -If some arrive out of order or are entirely missing there’s no system to fix the errors. The Transmission Control Protocol (TCP) numbers packets before sending them so that the receiver can correctly reorder the packets and request missing packets be resent.
