Tutorials are usually an opportunity for students to ask questions regarding
the material or the unit in general.
How many different combinations can be represented by using:
a. 4 bits
b. 13 bits
c. 32 bits
Convert the following numbers to 8-bit binary:
37, -56, 0, -1. Use the following representations:
a. Signed magnitude.
b. Ones-complement.
c. Twos-complement.
Convert the twos-complement binary representations to hexdecimal
and to octal, and show the corresponding C-language constant notations
(such as 0x0f).
If a byte contains 0xFF, what does this represent if it is treated
as a twos-complement (signed) number? As ones-complement? As unsigned?
Add the 6-bit twos-complement binary numbers 100101 and 100101.
What is the result? Did you get an overflow?
