How does TCP ensure that messages are transmitted correctly?

TCP, or Transmission Control Protocol, is designed to provide reliable communication over a network. One of the key mechanisms that TCP uses to ensure the correct transmission of messages is the retransmission of lost or corrupted packets. When data is sent over a TCP connection, packets are numbered sequentially, and TCP employs acknowledgments to confirm that packets have been received successfully. If an acknowledgment is not received within a specified time frame for a packet, TCP automatically retransmits that packet to ensure that no data is lost during transmission.

This reliability is a crucial aspect of TCP and distinguishes it from other protocols that may not provide the same level of assurance. By focusing on detecting packet loss and re-sending packets as needed, TCP can maintain the integrity and completeness of the data being transmitted, making it particularly suitable for applications where accurate data transfer is essential, such as file transfers, web browsing, and email.

The other options mentioned do not contribute directly to how TCP ensures message transmission correctness. Limiting the number of connected devices pertains more to network management rather than the reliability of message transmission. Encryption mechanisms, while important for security, do not address the issue of ensuring that messages are transmitted correctly. Lastly, segmenting data into smaller packets is a part of how TCP handles data
