How do pixels work?

Answer 1

Pixel is a contraction of "picture element"; the term is applied to a wide range of technologies - for example, digital cameras usually use a charge coupled device (CCD) sensor where photons of light affects the amount of charge on each pixel of the sensor. However, the image is copied to buffer memory in the camera - where each pixel is actually a few bytes of RAM, finally it's copied the solid state memory where, again, each pixel is a few bytes - but of solid state memory.

For display technologies, pixels might start on a computer hard drive, move to the computer memory, then to the display memory before describing elements on the LCD screen..

Answer 2

A pixel is simply a point (it can be circular, square) that is assigned a certain color. Thousands and thousands of these pixels are then placed in a specific row and column. They are small enough and are so close together that the eyes sees them as connected, making us believe that we are seeing an picture and not a bunch of dots or squares.
