A CRC code uses a generator polynomial of degree $16.$ Using

this generator polynomial in communication networks, the number of

redundant bits added to the data will be:

$($a$)16$ bits $($b$)17$ bits $($c$)15$ bits $($d$)$ neither a$,$ b or c

In stop$-$and$-$wait method of flow control, if $1000$ good data frames are

sent and received how many ACK frames have been sent by the

receiver?

$($a$)50$

$($b$)99$

$($c$)1000$

$($d$)$ neither a nor b nor c

A sender has a sliding window of size $1000.$ The first $200$ frames are

sent. The first ACK received is ACK $20.$ What frame is the receiver

expecting?

$($a$)19$

$($b$)20$

$($c$)201$

$($d$)200$
