DSSSB TGT CS 2023 Shift 2 – Question 182

Which of the given options best describes the truthfulness of the following statements?

i) In connectionless services of transport layer protocol, the packets are sent from one party to another with no need for connection establishment or connection release.
ii) In connection-oriented service of transport layer protocol, a connection is first established between the sender and the receiver.
iii) The User Datagram Protocol (UDP) is called a connectionless, unreliable transport protocol.

• i-True, ii-True, iii-True
• i-False, ii-True, iii-True
• i-True, ii-False, iii-True
• i-False, ii-False, iii-False

Evaluating each statement:
– Statement (i) is True: In connectionless transport service (such as UDP), each packet/datagram is routed independently without any prior connection establishment or subsequent connection termination.
– Statement (ii) is True: In connection-oriented transport service (such as TCP), a logical end-to-end connection is established first (e.g., via a 3-way handshake) before data exchange begins, and terminated after transfer completes.
– Statement (iii) is True: UDP (User Datagram Protocol) is a connectionless, unreliable, best-effort transport protocol because it does not guarantee delivery, order of delivery, or error recovery through retransmission.

Therefore, all three statements are True (i-True, ii-True, iii-True).
