Data representation

1. Number Systems

   • Binary
     • Base (2) system
   • Hexadecimal
     • Base (16) system
       • 1-9, a-f

2. Text

   • Ascii (7 bit)
     • 256 characters
   • Ubicode (16 bit)

3. Graphics

   • Vector Graphics
   • Bitmaps
     • Bitmaps are the most basic version of graphic representation.
       • Bitmaps rely on a grid system of pixels to map out how the image looks.
     • Bitmaps use binary representation to define each individual pixel.
       • Depending on how many bits are assigned to each pixel, determines the range of colours each pixel has access to.
