    2. 1.1.2 Information input, process and output
      1. Input: is when you enter data in the computer and then its processed and saved turning it into information useful for the computer

                1. The arithmetic logic unit is the one in charge of all the mathematical and logical things of the computer
                  1. The cache is a very important part of the perforamance of the computer because it process the information and is between the microprocessor and the RAM
                    1. The cache provides faster data that its not so complicated or that os frequently used
                      1. The flash memory is another very important part because its a writing and reading memory that its used when the devices are not on so it docent forget some things and tasks
