Assuming a data packet with a payload of $"111101"$ is transmitted from a retail store to the main office, and the CRC generator polynomial is $"1101".$

Calculate and provide the CRC bits associated with the given data payload. $($Show all the steps$)$

What bits are transmitted to the receiver?

Upon receiving a data packet with a payload of $"100101"$ at the main store, and with the associated CRC bits received correctly, using the same CRC generator $"1101,"$ explain the process by which the main store identify if the data packet has undergone any corruption during transmission. $($Show all the steps$)$
