2.4b: Character Storage
What is a Character Set?
A character set is a table that matches together a character and a binary value.
Character sets are necessary as they allow computers to exchange data.
Two common character sets are ASCII and Unicode.
(American Standard Code for Information Interchange)
Tiny Set of Characters
Less Memory Required per Character
Large Set of Characters
More Memory Required per Character
Character sets are logically ordered. For example, the binary code for A is 01000001, B is 01000010 and C is 01000011 as the code increases by 1 with each character.
2.4b - Character Storage:
1. What is a character set and why are they needed? 
2. Describe 3 differences between ASCII and Unicode. 
3. The binary code for the character P in ASCII is 01010000. State what the binary code for the character S would be.
