A Pixel can be defined as a Single point of an Image. For example, Take a Normal LCD/LED Television or Monitor of your PC / Laptop. Observe deeply. You'll see some Square boxes as shown in the below image.
A graphic monitor divides some Thousands to Millions of pixels in Hundreds to Thousands of Columns and Rows. The number of Bits in a pixels determines the Number of colors that will be shown in a Pixel. For example, Take 16 bit color monitor. It can show 16 bits for Each pixel, i.e., 2 to the power of 16 (216=65536) different colors or gray shades.
In color monitors, Each pixel is composed into RGB (1 Red, 1 Green, 1 Blue dots) mode. The 3 dots will converge at a Point. So, The Pixels will appear Turbulently.
Coming to the Quality point. The Quality of the Picture depends on the Resolution. i.e., How many Pixels are there and How many bits are Represented for each pixel. For example, A VGA screen uses 640x480 resolution. This is nothing but 300,000 pixels.
