User datagram protocol is called connectionless because
Multiple Choice Options
- A✓ Correct Option
all UDP packets are treated independently by transport layer
- B
it sends data as a stream of related packets
- C
it is received in the same order as sent order
- D
it sends data very quickly
Detailed Technical Solution & Explanation
The User Datagram Protocol (UDP) is categorized as connectionless because it does not establish a persistent session/circuit before transmission. Each UDP datagram is handled and routed as an independent, autonomous packet with no state preserved between successive packets.
Option Analysis:
•
Option A (all UDP packets are treated independently by transport layer): Correct; defines connectionless datagram packet handling.
•
Option B (it sends data as a stream of related packets): Describes TCP byte-stream oriented transmission.
•
Option C (it is received in the same order as sent order): Describes TCP in-order delivery; UDP datagrams may arrive out of order.
•
Option D (it sends data very quickly): Operational benefit, not the architectural definition of connectionless.
