Suppose Client A initiates a session with Server S$.$ At about the same time, Client B also initiates a session with Server S$.$ Provide possible source and destination port numbers for:

$($a$)[0\mathrm{.}25]$ The segments sent from A to S$.$

$($b$)[0\mathrm{.}25]$ The segments sent from B to S$.$

$($c$)[0\mathrm{.}25]$ The segments sent from S to A$.$

$($d$)[0\mathrm{.}25]$ The segments sent from S to B$.$

$($e$)[0\mathrm{.}25]$ If A and B are different hosts, is it possible that the source port number in the segments from A to S is the same as that from B to S$?$

$($f$)[0\mathrm{.}25]$ How about if they are the same host?
