The functional components of a computer can be categorized as follows:
Input Devices (All those devices using which instructions/information is fed into the computer) Ex. Keyboard, Mouse, Scanner, Joystick, touchpad, trackball etc.
Output Device (All those devices through which processed information is presented to the user ) Ex. monitor, printer, speakers etc
Memory and Storage Device: Its again of two types RAM and ROM. For easier understanding sake, RAM is the one with short term memory loss syndrome. Which means RAM only stores things for a short while, whereas ROM is the one with permanent storage capacity. RAM helps process the data faster and then store it in ROM for future use.
