Resolution is the quality of a computer-represented image or sound, especially concerning its capability to trick the eye (or ear) into perceiving it as a convincing duplicate of the original. In printers, quality is expressed in linear dots per inch (dpi). In soundboards, is expressed through the number of bits used to encode sounds. Resolution determines the amount of sound levels with which recorded sounds must be represented. Higher resolutions ensure greater fidelity to the original sound. Though a resolution of 8 bits is minimally acceptable for voice reproduction, 16-bit is required to reproduce the range of sounds in intricate pieces of music. In graphics, it is measured employing dots per inch (dpi) and color depth (the number of colors that make up the image). In monitors, it is expressed as the number of pixels horizontally and lines vertically onscreen. For example, a color graphics array (CGA) monitor displays fewer lines than a video graphics array (VGA) monitor; therefore, a CGA image appears more jagged than a VGA image.
