OUTPUT

//__ OUTPUT __// 1. An output device reverses the process, translating the digitized signals into a form intelligible to the user.

2. Since most information from a computer is output in either a visual or auditory format, the most common output devices are the monitor and speakers. These two devices provide instant feedback to the user's input, such as displaying characters as they are typed or playing a song selected from a play list

3. While monitors and speakers are the most common output devices, there are many others. Some examples include headphones, printers, projectors, lighting control systems, audio recording devices, and robotic machines. A computer without an output device connected to it is pretty useless, since the output is what we interact with.
 * CD, DVD and floppy disc are output devices that can also be used as storage and input devices. The computer sends data to the disc, where it is embedded and can be later retrieved.


 * An optical disc is a flat, usually circular disc which encode binary data in the form of pits and lands on a special material on one of its flat surfaces. The encoding pattern follows a continuous, spiral path covering the entire disc surface and extending from the innermost track to the outermost track. The data is stored on the disc with a laser or stamping machine, and can be accessed when the data path is illuminated with a laser.


 * Projectors are display devices that project a computer created image. The computer sends the image data to the video card which then sends the video image to the projector.


 * Plotters create a hard copy rendition of a digitally rendered design. The design is sent to the plotter via a graphics card, and creates the design using a pen.
