The Transmission Control Protocol (TCP) is a core protocol of the Internet Protocol Suite. It is reliable, ordered, and error-checked, ensuring that data is delivered across the network without errors and in sequence. Here are some statements about TCP, where one is false as per your request:
1. TCP provides end-to-end reliability. – This is true. TCP ensures that data sent from one end of a network to another is delivered reliably and in the same order it was sent.
2. TCP is connectionless. – This is false. TCP is a connection-oriented protocol, meaning it establishes a connection before data can be sent. UDP (User Datagram Protocol), on the other hand, is connectionless.
3. TCP uses handshaking protocols. – This is true. TCP uses a process called a three-way handshake to establish a connection before data is transferred. This process synchronizes both ends of a connection by exchanging SYN (synchronize) and ACK (acknowledge) messages.
4. TCP ensures data is delivered in order. – This is true. TCP sequences packets so that data can be reassembled in the order it was sent, ensuring that applications receive data in the correct order.
5. TCP guarantees delivery of packets. – This is true. TCP monitors packets for errors, retransmitting them if necessary to ensure they are delivered.
