Question

    Which of the following best describes the nature of TCP

    (Transmission Control Protocol) as a connection-oriented protocol?
    A TCP ensures that data packets are transmitted without error by relying on the physical layer of the network. Correct Answer Incorrect Answer
    B TCP provides a connectionless communication service where each data packet is treated independently. Correct Answer Incorrect Answer
    C TCP establishes a reliable connection between two endpoints before data transfer and ensures that all data is delivered in order. Correct Answer Incorrect Answer
    D TCP does not guarantee the delivery of data packets, allowing applications to handle retransmissions and error detection. Correct Answer Incorrect Answer
    E TCP uses a simple, stateless approach to handle data transmission, with no need for acknowledgments or flow control. Correct Answer Incorrect Answer

    Solution

    TCP (Transmission Control Protocol) is a connection-oriented protocol used in the transport layer of the Internet Protocol Suite. It is designed to provide reliable and ordered delivery of data between applications running on different devices across a network. Here’s how TCP’s connection-oriented nature is characterized: • Connection Establishment: Before data can be sent, TCP establishes a connection between the sender and receiver through a process called the three-way handshake. This handshake involves three steps: SYN (synchronize), SYN-ACK (synchronize-acknowledge), and ACK (acknowledge). • Reliability: TCP ensures that data packets are delivered reliably. It uses acknowledgments (ACKs) to confirm the receipt of packets. If a packet is lost or corrupted, TCP will retransmit it, ensuring that all data reaches the recipient correctly. • Order Preservation: TCP maintains the order of data packets. If packets arrive out of order, TCP will reorder them before delivering them to the application layer. This guarantees that data is received in the same sequence in which it was sent.
