The digits in 3DFF are 3, D, F, and 1. Their place values in base 16 are 16^2, 16^1, 16^0, and 16^0, respectively.

Answer


X2 = (3 x 16^2) + (D x 16^1) + (F x 16^0) + (1 x 16^0)
= 576 + 216 + 15 + 1
= 808

4) Given that the las two digits of your reg no is a number of binary and u = AS draw a true table of i) A & B given that B is equal to 00101001. ii) Find a or b. iii) find a or b and A

ANS

Given that the last two digits of your registration number is 04, which is equal to 00000100 in binary, we can construct the truth table for A & B as follows:

i)

ABA & B
000
010
100
111
As you can see, the output of A & B is 1 only when both A and B are 1. Otherwise, the output is 0.

ii)

The truth table for A or B is as follows:

ABA or B
000
011
101
111
As you can see, the output of A or B is 1 when at least one of A and B is 1. Otherwise, the output is 0.

iii)

The truth table for A or B and A is as follows:

ABA or B and A
000
011
101
111
As you can see, the output of A or B and A is always 1. This is because A or B is always 1 when at least one of A and B is 1, and A is always 1.
