Let g1(x) = X5 + x + x + 1. Consider the information bits (1,1,0,1,1,0,1,1,0,1). Find the codeword corresponding to these information bits if g1(x) is used as the generating polynomial. [5 marks] From the following two 16-bit integers: 1011110001001101 and 1011010111001000, find the internet checksum of the two messages (16-bit integers). Show your calculation.
