Consider the following statements:
(i) Address Resolution Protocol (ARP) provides a mapping from an IP address to the corresponding hardware (link-layer) address.
(ii) A single TCP segment from a sender S to a receiver R cannot carry both data from S to R and acknowledgement for a segment from R to S.
Which ONE of the following is CORRECT?
- Both (i) and (ii) are TRUE
- (i) is TRUE and (ii) is FALSE
- (i) is FALSE and (ii) is TRUE
- Both (i) and (ii) are FALSE
Correct answer: (i) is TRUE and (ii) is FALSE
Solution
Statement (i) is correct because ARP indeed maps IP addresses to hardware addresses, facilitating communication over a network. Statement (ii) is incorrect as TCP segments can carry both data and acknowledgements in the same segment, allowing for efficient communication.
