Pixels are a single dot in an image. A known 64 pixel image is the chessboard 8 by 8 "pixels". Each square is one pixel.
So the more pixels you have in an image makes it sharper (potentionally). So the number of pixels in a picture are the colums multiplied by rows. By Kodak 1152 x 864 pixels are close to 1 megapixel.
Each pixel can only be 1 colour but the number of possible colours depends on hardware and software. In the chessboard each "pixel" can only be white or black, that is 1 bit. Most common is 16.7 million colours or 24 bits.
