Bit and Byte, Datastructures, Modeling

I searched for short youtube videos, they explain it 10x better than I ever could.

Bit and Byte

• this video explains decimal and hexadecimal very well
  • octal would be base 8 (not exam relevant)
• RGB values are split into 3 parts
  • #58A68F → 58 red, A6 green, 8F blue

Floating Point Numbers

• Check out this video from computerphile, they explain it very well
• this other video is a lot faster but requires I’d say a good idea of binary to grasp

Data Types

• boolean
• int
• float (double)
• string

Data Structures

• https://www.youtube.com/watch?v=cQWr9DFE1ww

  • not just the BA1 data structures, still very useful

• Array

• List/Vector

• Matrix

  • Array of Arrays

• Dataframe

  • Matrix but with multiple data types
  • imagine matrix meets excel sheet, but programmatically

• Graph

Modelling
