C S E 3 6 0 | 1 Abdulwahab Alkharashi Hany Rashwan Homework #1 HW1-1. A: For the HW, MS Words, PDF or text format is accepted, and for the labs it should be only formatted as text source (*.s) file. B: There is NO LATE homework or lab will be accepted unless there is an approval from the instructor before the assigned due time. HW1-2. 101.101 (binary) = 1*2 2 + 0*2 1 + 1*2 0 + 1*2 -1 + 0*2 -2 + 1*2 -3 = 5.625 HW1-3. A = 1111101 (In Binary) B = 175 (In Octal) C = 7D (In hexadecimal) D = 65 (6*20 1 + 5*20 0 ) (In base 20) E = 0001 0010 0101 ( In BCD) HW1-4. a. 1001,1000 b. 24 = 0001, 1000 Invert 1110, 0111 +1 1110,1000

Unformatted text preview: 011 b. 0110 1011 0001 6 + -5 1 C S E 3 6 0 | 3 HW1-6. a. 8+ 5 = 01000 + 00101 = 01101 = 13 (decimal) b. 7 + -5 = 00111 + 11011( by inverting 5) = 0010 c.-11 + -7 = 10101 (by inverting 11) + 11001 ( by inverting 7) = 01110 HW1-7. a.-(2 14-1) to (2 14-1) b.-(2 14 ) to (2 14-1) HW1-8. 2,347 = 1001 0010 1011 (in 12 bits) HW1-9. Since information system is based on power of 2 in computing, scientists believe that the numbers that are powered by multiple of 10 should be used to determine the value of bites. So it has been approximated to the metric system. For instance, 2 10 is equals to 1024 which approximated to the value of 10 10 which is kilo in the metric system....
