Question 1: Differentiate between hexadecimal and octal number system
Answer:
- octal - base 8
- hexadecimal - base 16
Octal and hex are used to represent numbers instead of decimal because there is a very easy and direct way to convert from the "real" way that computers store numbers (binary) to something easier for humans to handle (fewer symbols). To translate a binary number to octal, simply group the binary digits three at a time and convert each group. For hex, group the binary digits four at a time.
