4) Given the complete list of bytes in a UDP datagram below (the 0x0000 is the yet unknown checksum), calculate the hexadecimal, additive inverse checksum as we did in class. For your convenience, the binary equivalent of these bytes is listed. Remember, the checksum is 16 bits, but it's based on the sum of bytes. 0x87 = 1000 0111 0xE3 1110 0011 0xF7 1111 0111 x79 0111 1001 0x9C 1001 1100 0xD0 1101 0000 0x14-0001 0100 0x58 = 0101 1000 0x000000 0000 0x000000 0000 0x67 0110 0111 0x03 0000 0011 0x3B = 0011 1011 0x28 0010 1000 5) Given the complete list of bytes in a received UDP datagram below, determine whether the data arrived safely ("safe" or "not safe"). The 7th and 8th bytes (bottom two entries of left column) are the checksum word where the 7th byte is the high order byte of the checksum word. 0x0B0000 1011 0x70 = 0111 0000 0x3A= 0011 1010 0x9D 1001 1101 0x79 = 0111 1001 0x550101 0101 0x310011 0001 0x7B = 0111 1011 0x40 0100 0000 0x5C 0101 1100 0x36 0011 0110 0x46 0100 0110 0x78 0111 1000 0x29 0010 1001 4) Given the complete list of bytes in a UDP datagram below (the 0x0000 is the yet unknown checksum), calculate the hexadecimal, additive inverse checksum as we did in class.
