• Four Basic Components
• Hardware
• Software
• Data
• User

2
HARDWARE

• actual circuitry and physical equipment of a
  computer system.
• Those parts of the computer that are tangible or
  those parts that you can "reach out and touch."

3
SOFTWARE

• Programs that are written that instruct the
  computer to process data.

4
DATA

• Facts and figures to be manipulated by a program.
• Information and Data are different in computer
  jargon.

• STORAGE (MEMORY)

6
INPUT

• keyboard

MOTHERBOARD

• Microprocessor
• Bus--electronic pathways connecting all the
  important components of the processing unit
• System clock measured in megahertz(MHz)
  mega(millions) and hertz(cycles per second)
