Question: In TCP, if the ACK value is 200, then byte _______ has been received successfully.
Answer:
In TCP, if the ACK value is 200, then byte 201 and all bytes before it have been received successfully.
The ACK value in a TCP segment is the next expected sequence number that the receiver is waiting for. It indicates the byte number that the receiver expects to receive next. In other words, the ACK value acknowledges the receipt of all data up to but not including the ACK value.
For example, if the receiver has successfully received bytes 1 to 200 and is expecting byte 201 next, then it will send an ACK segment with an ACK value of 201. If the sender receives this ACK segment, it knows that bytes 1 to 200 have been received successfully and can proceed to send the next segment starting from byte 201.
Therefore, if the ACK value is 200, it means that all bytes up to byte 200 have been received successfully, and the receiver is expecting byte 201 next.
MCQ: In TCP, if the ACK value is 200, then byte _______ has been received successfully.
Explanation:
In TCP, if the ACK value is 200, then byte 201 and all bytes before it have been received successfully.
The ACK value in a TCP segment is the next expected sequence number that the receiver is waiting for. It indicates the byte number that the receiver expects to receive next. In other words, the ACK value acknowledges the receipt of all data up to but not including the ACK value.
For example, if the receiver has successfully received bytes 1 to 200 and is expecting byte 201 next, then it will send an ACK segment with an ACK value of 201. If the sender receives this ACK segment, it knows that bytes 1 to 200 have been received successfully and can proceed to send the next segment starting from byte 201.
Therefore, if the ACK value is 200, it means that all bytes up to byte 200 have been received successfully, and the receiver is expecting byte 201 next.
