Question
Since UDP is a connectionless protocol, source and destination ports are not needed within the UDP header.
True
False
Since UDP is a connectionless protocol, timeout periods between segment receipt and ACK are not required.
True
False
Select the correct statement(s) regarding TCP.
a. TCP window size, which is given in bytes, changes in response to network congestion
b. TCP guarantees the proper sequencing of received data
c. With TCP, if a segment is not received and acknowledged (ACK), then it is retransmitted
d. All of the above are correct statements
a. TCP window size, which is given in bytes, changes in response to network congestion
b. TCP guarantees the proper sequencing of received data
c. With TCP, if a segment is not received and acknowledged (ACK), then it is retransmitted
d. All of the above are correct statements
Explanation / Answer
Even though UDP is connectionless protocol,
source and destination port are needed in UDP header along with total length and checksum and UDP data
Hence the statement is FALSE
Since, UDP is faster and there is no flow control. thus acknowledgment. error checking is not done by UDP.
Hence, Since UDP is a connectionless protocol, timeout periods between segment receipt and ACK are not required is TRUE
TCP
answer: option(d)
Since TCP provides reliable communication and proper sequences of data along with retransmission of segment if not Acknowledged, hence all statements are true
