Question: Convert 1D16 to base 10. Show or explain your work for credit. - CORRECT
ANSWER✔✔A = 10
B = 11
C = 12
D = 13
1D base 16 -> base 10
(1 * 16^1) + (13 * 16^0)
16 + 13 = 29
Question: What is at least one reason why modern CPU clock speeds have not generally
exceeded about 5 GHz? - CORRECT ANSWER✔✔Modern CPU clock speeds don't usually exceed
5 GHz because the performance doesn't get that much better, and it would also require a more
expensive cooling system.

Question: ____ always uses a fixed number of bits, with the leftmost bit representing the sign--
along components known as the mantissa and exponent.
- Ones complement
- Floating point
- Twos complement
- Scientific point - CORRECT ANSWER✔✔Floating point
Question: ____ occurs when the absolute value of a computational result contains too many
bits to fit into a fixed-width data format. - CORRECT ANSWER✔✔Overflow
