What is a pixel?
“The pixel (a word
invented from "picture element") is the basic unit of programmable
color on a computer display or in a computer image. Think of it as a logical -
rather than a physical - unit. The physical size of a pixel depends on how
you've set the resolution for the display screen.”

What is picture resolution?
Picture resolution is the amount of pixels on the screen that represent an image you see. eg(1920x1080)
"Resolution refers to the number of pixels in an image. Resolution is sometimes identified by the width and height of the image as well as the total number of pixels in the image. For example, an image that is 2048 pixels wide and 1536 pixels high (2048X1536) contains (multiply) 3,145,728 pixels (or 3.1 Megapixels). You could call it a 2048X1536 or a 3.1 Megapixel image."

What is Image quality?
Image quality is similar to picture resolution. Image quality describes the images sharpness, its similar to picture resolution because to have an sharper image you need more pixels meaning a higher picture resolution.
"Assessment or subjective measure of how accurately or fully an image of a subject represents that subject."

Intensity:
What is intensity(pixel values)?
Intensity in pixel values is the different shades of a colours.
For a grayscale images, the pixel value is a single number that represents the brightness of the pixel. The most common pixel format is the byte image, where this number is stored as an 8-bit integer giving a range of possible values from 0 to 255. Typically zero is taken to be black, and 255 is taken to be white
