OUTPUT DEVICES


            An output device is a physical component that converts the processed data or information into a human readable format.
            Some of the commonly used output devices are:

            Monitor (Visual Display Unit)

            Monitor is a standard output device that is similar to a television screen. It is also known
            as Visual Display Unit (VDU) or console. An input from any input device such as a keyboard
            can be seen on the screen simultaneously. There are different types of monitors available
            in the market depending on the size and color.

            These days the most widely used monitors in computers, tablets, smartphones, Smart
            TV, etc. is LCD (Liquid Crystal Display). Its screen is made up of smaller elements called
            pixels.  Resolution  of  any  display  unit  is  the  number  of  horizontal  and  vertical  pixels.   Monitor
            A higher resolution provides a smoother, sharper, clearer image.
            Printer

            A printer is an output device that is used to get the output on a physical medium like paper. The output on the screen
            is called a soft copy whereas the output from the printer is called a hard copy. It can be used to print both text and
            graphics. The two most common types of printers used these days are inkjet and laser printers.

                                           Inkjet Printer
                                           Inkjet printers are also called photo printers. They are used to print both in colored
                                           or black & white format for home or small business purposes. The speed of an
                                           ink-jet printer is measured by the number of Pages Per Minute (PPM). Mostly ink-
                                           jet printers print from 12 to 36 pages per minute.

            Laser Printer
            A laser printer works just like a photocopy machine that prints the output at high-speed
            and good quality. It creates images using a laser beam and powdered ink called toner. It
            is more expensive than inkjet printers and can be used for home or business purposes.

                                           Plotter
                                           A plotter is an output device similar to a printer but used to print vector graphics
                                           like architectural  designs,  maps, computer aided  drawings  etc.  by plotting
                                           lines using a pen. A printer uses a technology of joining closely spaced series of
                                           small dots to print whereas a plotter draws using a pen. Multicolor plotters use

                     Plotter               different-colored pens to draw in different colors.
            Speakers

            Speakers are an output device that produce sound waves in the form of an output
            which can be heard by a listener. Speakers can be attached to a computer or to
            any other system like smartphones, tablets, Smart TV, etc. to enhance the volume
            and the quality of audio output. The different kinds of speakers range from simple,
            two-speaker output devices to surround-sound multi-channel units.                      Speakers
