Suppose you have following two bytes data (although UDP uses a 16-bit word but we use 8-bit here for the sake of simplicity)

Byte1: 00110100

Byte2: 01101001

1. Compute the checksum (this checksum is sent by the sender in UDP header)
2. In flight (over the network), least significant bit is corrupted to 1 for Byte1, and least significant bit is corrupted to 0 for Byte2. With this data, what checksum will be computed at the receiver side
3. If UDP receiver computes the Internet checksum for the received UDP segment and finds that it matches the value carried in the checksum field, can the receiver be absolutely certain that no bit error have occurred? Explain.
