A UDP header does not have Sequence number and Acknowledgement number fields. Is it an advantage or a disadvantage? Explain your answer in detail.
User Datagram Protocol
The unreliable and connectionless transport protocol is known as User Datagram Protocol. It is a lower version of TCP that's why it has far less latency rate than TCP and UDP does not provide Flow control, sequencing and acknowledgement of sending data but it provides error checking facility by using Checksum.
So we can say that as the UDP does not have Sequence number and Acknowledgement number it does not provide reliable service and no surety of sending data as this Sequence number and Acknowledgement number is used to initialize session while sending data from source to destination.
