d) A unit of memory
Answer:
a) The smallest unit of a digital image
Explanation:
A pixel, short for “picture element,” is the smallest unit of a digital image or display. Pixels are tiny squares that combine to form the images we see on computer monitors, smartphones, and other digital displays.
Each pixel in an image or display can have its own color and brightness value. The resolution of a digital image is determined by the number of pixels it contains, with higher pixel counts providing greater detail and clarity.
Pixels are a fundamental concept in digital imaging and graphics, and understanding them is key to working with digital photography, video, and display technologies.
