Data and number representation

• Positional encoding: binary, hex, decimal
• Internal vs. external representation
• Conversion between different representations
• Key ideas: bits can represent ANYTHING. With n bits we can represent at most 2^N things
• Apply above rule to represent characters (ASCII), unicode, colors ….
• The data type of a variable determines its representation in memory AND the number of bits used to store each variable
