Unit 2.4 Computational Logic
  1. Why and How computers use Binary
    1. RAM - RAM uses charged or uncharged capacitors to show it
      1. Hard Disk - Hard Disks use different levels of magnetism
        1. Optical Discs - Uses whether or not it reflects light
          1. Solid States Drives use a flow of electrons to show information
            1. We use binary to store data in smaller chunks called bits.
            2. Logic Gate Notation
              1. A AND B
