- - - - Byte (8 bits)
      - Kilobyte (1000 Bytes)
      - Nibble (4 Bits)
      - Megabyte (1000 Bits)
      - Bit (1 Bit)
      - Gigabyte (1000 Bits)
      - Terabyte (1000 Bits)
      - Petabyte (1000 Bits)
    - - Hexadecimal
        
        Hexadecimals are a base 16 system used to simplify how Binary is represented.
      - Images
        
        color depth
        
        the number of bits used to indicate the color of a single pixel.
        
        metadata
        
        pixels and resolution
        
        pixels are the small dots that make up a picture.
      - Characters
        
        Characters are when you type out something and your computer translates it by ASCII or Extended ASCII.
      - Sound
      - Binary
        
        Binary is the computers language, 1's and 0's.
    - - RAM vs ROM
        
        RAM (aka Random-AccessMemory) is a short term memory storage space that can be easily accessible. This data doesn’t save once the computer is turned off this means it is volatile.
        ROM (aka Read Only Memory) is a memory space that cannot be changed and saves once the computer is turned off this means its non-volatile.

        Purpose of the CPU
        
        Fetch-Execute Style
        
        store - The newly processed is written back into the memory location on the HDD or SSD.
        
        Fetch - The CPU retrieves instructions from a systems hard drive or solid state drive and stores them in a register location.
        
        Decode - The CPU determines which system components are required in the execution of the instruction, outlining parameters for a successful execution.
        
        4 Execute - The CPU assigns the specific actions to the relevant system components in order to carry out the initial program instructions, processing the actual data.
