Final answer:
The term for the tiny colored squares that make up a digital image is 'pixels,' which are the smallest units that blend to form the full image.
Step-by-step explanation:
The term that refers to tiny individually colored, light-sensitive squares or picture elements that make up a digital image file is pixels. These pixels are the smallest unit of a digital image, and when you look at a digital image from a normal viewing distance, they blend together to form a cohesive picture. In devices like LCD televisions and digital cameras, these pixels are composed of sub-pixels with red, green, and blue filters, which can be controlled independently to create the full spectrum of colors when light passes through them.
