Computer Technology 101

The five (5) major components of a Personal Computer (PC) system are the following, in the order of their importance:
1.  Central Processing Unit (CPU) is the component that does all the computations and control of the PC system.
2.  Main/Internal/Primary Memory component is where all the raw data and the computed data is stored.
3.  Input Device components are the device that a user will use to communicate with the CPU.
4.  Output Device components is how the PC system will be able to communicate to the user.
5. Secondary/Drive Storage Device components are where the user must save his data and his programs if he wants to use them again after turning off the PC system.

INPUT DEVICES =====> CPU <=====> INTERNAL MAIN MEMORY
(keyboard, mouse)             |                   (RAM, ROM)
                                          |========> SECONDARY STORAGE DEVICE
                                          |                    (hard drive, floppy drive)
                                          |========> OUTPUT DEVICES
                                                               (console, printer)

Happy computing!
