- - - - A desktop monitor that uses a cathode-ray tube to
        produce images
      - Bigger and bulkier LCD monitor, consume more
        power and prone to screen flicker.
    - - A desktop monitor that uses a liquid crystal
        display to produce images.
      - – Offers sharp, flicker-free images, lighter and
        thinner, and more energy saving compared to CRT
        monitors
    - - A display device that uses gas plasma technology
        to produce images
      - Offer larger screen size and richer colors than LCD
        monitor, but more expensive
    - - A display that uses an array of light-emitting
        diodes to produce images.
      - – Offers better color quality, clarity, and better
        energy savings.
- - - - – Forms characters and graphics on a piece of paper
        by striking a mechanism against an inked ribbon
        that physically contacts the paper.
      - Noisy, and print quality is slightly less clear
      - Used in business for routine jobs such as printing
        labels or multilayers forms.
      - – Examples
        
        dot-matrix printer
        
        line printer
    - - Form characters and graphics on a piece of paper
        without actually striking the paper
      - – Form characters and graphics by spraying ink,
        using heat, or using pressure
      - – Quiet, and better print quality
      - Examples
        
        Ink-jet printer
        
        Sprays tiny drops of liquid ink onto a piece of

        Uses laser beam and powdered ink to transfer
        images onto paper.
        
        high-speed and high quality nonimpact printer
        
        Thermal printer
        
        Generates images by pushing electrically heated
        pins against heat sensitive paper
        
        Plotter
        
        used to produce high-quality
        drawings such as blue-prints, maps and circuit
        diagrams
