the three functions of a harddrive

INPUT HARDWARE


  • without instructions and info the comp doesn't know what to do
  • putting data into the comp
  • referred as data entry


PROCESSING AND STORAGE



  • processor is where the work is
  • recieves info
  • stores it as memory
  • made of two parts (cpu and and main storage)

OUTPUT

  • sends the data saved back to the operator
  • wouldn't know what the comp had done
  • would be useless without this
  • hard copys usually printed on paper through printer
