1 starting task 2 1) 103 3 2) 10 10011011 4 3) 10101001 x wrong numbers used 5 4) binary, denary, hexadecimal, octodecimal (base 8) x natural rational integer real 6 7 from gcse remember spliting a binary number every 4 bits and convert to hex 8 9 when you have signed bit it means - of the bit that is signed (usualy 128) + all the other values 10 your colums would be -128, 64, 32, 16, 8, 4, 2, 1 11 if you have less bits it might look like this -8, 4, 2, 1 12 same for if you have more bits 13 14 we did some fixed point binary, it goes like this, -128, 64, 32, 16, 8, 4, 2, 1, 0.5, 0.25.. 15 it is clear why we use floating point numbers 16 17 THE EXAM THINKS THAT 1G = 1000KB 18 THEY CALL 1024KB = 1 Gibibyte 19 20 2^n is the maximum amount of values, n = the number of bits
