10. Computing Fundamentals The Four Main Components of a Microcomputer Back INPUT DEVICES Input devices allow us to enter information into the computer. They include keyboards, mice, scanners, and microphones. PROCESSING DEVICES Processing components manipulate the information once it is "in" the computer. In the microcomputer there is a set of common components consisting of the central processing unit (CPU), interface components, and memory (RAM). STORAGE DEVICES Storage devices store the entered information and programs for future use. Common storage devices include hard disks, floppy disks, and CD-ROMs. OUTPUT DEVICES Output devices are how the manipulated information is returned to us. They commonly include video monitors, printers, and speakers. Parts of the System Unit
