            1. Solid State Drive: Non-Volatile Memory storage used to store and access data, much like a computer RAM
            2. ROM: the built-in computer memory that can only be read not written ex. the programming that runs the computer. ROM memory is non-Volatile.
              1. Hard Disk Drive: Non-Volatile Storage where the computer main memory is stored. Contains moving parts.
              2. Graphics Card: An internal board that creates a picture on a display.
                1. Sound card: an expansion card used for producing sound on a computer.
                  1. Input and Output Devices
