DESCRIBE THE PRINCIPLES OF OPERATION OF THE FOLLOWING OUTPUT DEVICES: INKJET, LASER
AND 3D PRINTERS; 2D AND 3D CUTTERS; SPEAKERS AND HEADPHONES; ACTUATORS; FLAT-PANEL
DISPLAY SCREENS, INCLUDING LIQUID CRYSTAL DISPLAY (LCD) AND LIGHT-EMITTING DIODES (LED)
DISPLAY; LCD PROJECTORS AND DIGITAL LIGHT PROJECTORS (DLP)
INKJET PRINTERS - THESE ARE DEVICES THAT PRINT SOFT-COPY ITEMS INTO HARD-COPY ONES. IT USES INK AND SPRAYS DROPLETS OF INK TO CREATE AN IMAGE/DOCUMENT.
LASER PRINTERS - THESE ARE DEVICES WHICH USE DRY-INK INSTEAD OF WET INK LIKE THE INKJET PRINTER. IT USES STATIC ELECTRICITY (POSITIVE/NEGATIVE CHARGE) TO PRINT, AND THEN THE INK AND PAPERS IS HEATED TO BE FUSED.
3D PRINTERS - THESE DEVICES ARE USED IN CAD, WHERE IT PRINTS 3D OBJECTS USING DIFFERENT MATERIAL.
2D/3D CUTTERS - THESE CUT OBJECTS. THE DIFFERENCE BETWEEN 2D AND 3D IS THAT THEY 3D CAN RECOGNIZE X-Y-Z CO- ORDINATES. 3D CUTTERS CAN CUT: GLASS, CRYSTAL, POLYMER ETC.
SPEAKERS/HEADPHONES - DIGITAL DATA IS CONVERTED TO ANALOGUE DATA USING A DAC, THROUGH AN AMPLIFIER, THE DEVICE THEN PLAYS IT OUT LOUD.
LCD/LED DISPLAYS - LIQUID CRYSTAL DIODE/DISPLAY (LCD) & LIGHT EMITTING DIODE (LED) ARE DEVICES WHICH EMIT LIGHT, THESE ARE TINY AND MAKE UP COMPUTER SCREENS AND SUCH.
LCD/DLP PROJECTORS - THESE DEVICES (DIGITAL LIGHT PROJECTORS (DLP) GIVE OUT BEAMS OF LIGHT AND CAN BE SHOWN ONTO A LARGER SCREEN OR ONTO INTERACTIVE WHITEBOARDS

DESCRIBE HOW THESE PRINCIPLES ARE APPLIED TO REAL-LIFE SCENARIOS, FOR EXAMPLE: PRINTING
SINGLE ITEMS ON DEMAND OR IN LARGE VOLUMES; USE OF SMALL SCREENS ON MOBILE DEVICES
INKJET PRINTERS - EVERYDAY-USE, PRINTING DOCUMENTS, PRINTING IMAGES.
LASER PRINTERS - EVERYDAY-USE, PRINTING DOCUMENTS, PRINTING IMAGES. BUT MUCH FASTER ALTHOUGH LOWER QUALITY.
3D PRINTERS - MODELLING, ART, VISUAL REPRESENTATION OF OBJECTS. 2D/3D CUTTERS - INDUSTRIAL USE, DESIGNING SPEAKERS/HEADPHONES - EVERYDAY-USE, CONCERTS ETC.
LCD/LED DISPLAYS - COMPUTERS, TV’S, NORMAL LIGHTING
LCD/DLP PROJECTORS - EVERYDAY-USE, MEETINGS, FOR INTERACTIVE WHITEBOARDS
