Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
User datagram protocol is called connectionless because ____
A
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
Explanation: 

Detailed explanation-1: -In contrast, UDP is considered a connectionless protocol because it doesn’t require a virtual circuit to be established before any data transfer occurs. The communication protocol just sends the packets, which means it has much lower bandwidth overhead and latency.

Detailed explanation-2: -UDP (User datagram protocol) is called a connectionless, unreliable transport protocol. It does not add anything to the services of IP except providing process to process communication. There is no flow control, error control and congestion control mechanism in UDP.

Detailed explanation-3: -The User Datagram Protocol (UDP) is simplest Transport Layer communication protocol available of the TCP/IP protocol suite. It involves minimum amount of communication mechanism. UDP is said to be an unreliable transport protocol but it uses IP services which provides best effort delivery mechanism.
