- 1Outputtakes data produced by computer and turns it into a form humans can understand. Must be able to output information in a suitable format. Output formats: visual, audio and movement
- 2LCD Monitorsliquid crystals contain red, green and blue diodes to form each pixel. Back lit using light emitting diodes (LEDs)
- 3OLED Monitorsbrighter, thinner and lighter than LCD or LED. Screens are plastic so more flexible therefore you can make curve screens. Aren't as robust as LCD (dont last as long)
- 4Inkjet printereach feature a print head containing thousands of tiny holes. These tiny openings drop microscopic droplets of ink onto the paper in the printer at a speed. Inkjet machines use a liquid ink or a liquid that contains solid pigments in suspension
- 5Dot Matrix PrinterThe dot matrix printer uses one or two columns of dot hammers that are moved across the paper. The hammers rapidly press the ribbon into the paper, which causes the ink to be deposited. The more hammers, the higher the resolution. These printers are useful when multi-part stationery is required, and they can operate in damp or dirty environment
- 63D PrinterAn End User uses computer aided design (CAD) software to design a 3D product.
This design is exported in STL/OBJ format ready for the printer. Once the setup is complete, the information is sent via a cable to the printer. The actual printer uses plastic to create the product. The plastic is fed into the printer like string and heated up. The nozzle moves around the base of the printer doing one layer/cross section at a time - 7PlotterA plotter is a machine that produces vector graphics drawings. Plotters draw lines on paper using a pen, or in some applications, use a knife to cut a material like vinyl or leather. In the latter case, they are sometimes known as a cutting plotter
- 8Speakeroutput hardware device that connects to a computer to generate sound. The signal used to produce the sound that comes from a computer speaker is created by the computer's sound card
- 9Actuatorpiece of equipment that produces movement when given a signal. Used in industrial automation, robots... Can be used to open a window, turn a wheel etc..
- 10Haptictechnology that uses touch to control and interact with computers. A user may apply a sense of touch through vibrations, motion or force. Haptic technology is used mainly in creating virtual objects, controlling virtual objects or in the improvement of the remote control of machines and devices
