Megapixel
The number of pixels on the surface of a camera's sensor(one megapixel = one million pixels). The larger the number of megapixels, the larger the image that can be printed

Resolution
The ability of a lens or optical system to show detail. The higher the resolution, the more detail. More pixels = higher resolution.
Sensor
The light-sensitive device in a digital camera that captures the image projected by the lens. The more pixels a sensor has, the more detail it can capture and the larger the files will be.
Memory Card
A flash-memory storage device used inside digital cameras to store image files.
