Wikipedia
Pixel

In digital imaging, a pixel, pel, dots or picture element is a physical point in a raster image, or the smallest addressable element in an all points addressable display device; so it is the smallest controllable element of a picture represented on the screen. The address of a pixel corresponds to its physical coordinates. LCD pixels are manufactured in a two-dimensional grid, and are often represented using dots or squares, but CRT pixels correspond to their timing mechanisms and sweep rates.

Each pixel is a sample of an original image; more samples typically provide more accurate representations of the original. The intensity of each pixel is variable. In color image systems, a color is typically represented by three or four component intensities such as red, green, and blue, or cyan, magenta, yellow, and black.

In some contexts (such as descriptions of camera sensors), the term pixel is used to refer to a single scalar element of a multi-component representation (more precisely called a photosite in the camera sensor context, although the neologism sensel is sometimes used to describe the elements of a digital camera's sensor), while in others the term may refer to the entire set of such component intensities for a spatial position. In color systems that use chroma subsampling, the multi-component concept of a pixel can become difficult to apply, since the intensity measures for the different color components correspond to different spatial areas in such a representation.

The word pixel is based on a contraction of pix (from word "pictures", where it is shortened to "pics", and "cs" in "pics" sounds like "x") and el (for "element"); similar formations with el  for "element" include the words voxel, texel and maxel (for magnetic pixel).

Pixel (webcomic)

Pixel is a webcomic written by Chris Dlugosz, first published on June 14, 2002. It is set in the aptly named "pixel universe", inhabited by pixels, voxels, vectors, plasmas (a satire on the plasma screens used by Apple computers), and polygons. The comic is known for its very literal sense of humor, and its constant breaks of the fourth wall. The text of the comic is written entirely in upper case with very little punctuation other than the occasional hyphen or exclamation point. Each comic comes with a short note, usually split into three lines at seemingly arbitrary points. These are also written in capitals with no punctuation, and usually explain or expand upon the strip.

Material from Pixel is included in Attitude 3: The New Subversive Online Cartoonists.
