What is the abbreviation of Picture Element (PIXEL)? Definition
A pixel is the abbreviation for picture element. A pixel is the smallest component of an image or picture. Pixels are arranged in rows and columns in order to produce a complete image.
The number of pixels in an image is called resolution. Screen resolution is rated by the number of horizontal and vertical pixels; for example, 1024×768 means 1,024 pixels are displayed in each row (columns), and there are 768 rows (lines). The greater the number of pixels per inch the greater the resolution.
Screen image sharpness is sometimes expressed as dpi (dots per inch). Dots per inch is determined by both the physical screen size and the resolution setting.
