Megapixels
An image sensor is made up of many tiny light sensing devices called pixels. If you zoom into a photo in your imaging software, eventually you will see that it is made up of tiny squares, each of these is a pixel on the sensor. The term Mega means million, so the megapixel count is the number of pixels on an image sensor in the millions. A 14 megapixel sensor thus contains 14 million pixels. Higher pixel counts do not necessarily mean better image quality but with more pixels you will be able to print larger photos.
