Which of the following characteristics is unique to TCP

Solution

TCP (Transmission Control Protocol) ensures reliable communication through features such as acknowledgment, retransmission, and sequence numbers. These mechanisms collectively provide guaranteed packet delivery to the receiving end. 1. TCP establishes a connection-oriented session, ensuring that all packets are received in the correct order. 2. In case of loss or corruption, TCP retransmits the missing or damaged packets, maintaining data integrity. 3. This reliability makes TCP suitable for applications like web browsing, email, and file transfers. ________________________________________ Why Other Options Are Incorrect: • A) Faster data transmission: UDP (User Datagram Protocol) is faster due to its lack of overhead for error correction. • B) Stateless communication: UDP operates without maintaining a session state, unlike TCP. • D) Multicasting capability: UDP supports multicasting, not TCP. • E) Minimal resource usage: UDP uses fewer resources due to its simpler design, as it lacks reliability mechanisms.
