In sliding window flow control, if window size is 63, what is the range of sequence numbers ?

  • A.0 to 63
  • B.0 to 64
  • C.1 to 63
  • D.1 to 64

Answer: A

Correct answer: 0 to 63

A window of 63 requires 64 distinct sequence numbers, one more than the window, so that a full window cannot be confused with an empty one. Numbering from 0 gives the range 0 to 63.
