solution:- According a no question, we have to to o the e the the given given internet internet alculate checksum for the following data. 29 91 8E AD CF 85 61 AA 83 03 7C OF 0 39 91 AO 09 Sol so 39.91 8 E 90 CF 85 61 AA 83 03 Te Of AO 09 First of all, we should have the knowledge about hema decimal digits. Hexa decimal values starts from 0-15 . . 10 1 2 13 14 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F.
