When an in-order segment with the expected sequence number arrives and all data up to the expected sequence number has already been acknowledged.
It signifies that the receiving end of a communication has received all the preceding segments in the correct order and is ready for the next segment.
In a reliable data transmission protocol, such as TCP (Transmission Control Protocol), segments are assigned sequence numbers to ensure ordered delivery. The expected sequence number represents the next segment's sequence number that the receiver anticipates receiving.
When the in-order segment with the expected sequence number arrives, it implies that all preceding segments, including any potential out-of-order segments, have already been received and acknowledged. This indicates that the transmission has been successful up to this point, and the receiver can process and acknowledge the current segment.
This mechanism helps maintain the integrity and order of the transmitted data, ensuring reliable and accurate communication between the sender and receiver.

The string primitive that will copy a BYTE from the memory location pointed to by ESI to the memory location pointed to by EDI is: MOVSB
What is The MOVS instruction?The code snippet responsible for copying a byte from the memory location indicated by ESI to the memory location indicated by EDI belongs to the string primitive.
To move a byte, word, or doubleword from one memory location (ESI) to another (EDI), the MOVS command is utilized. The MOVS instruction is employed in this scenario to transfer a byte (specified by the 'B' suffix) from ESI to EDI.
