What is a pixel in the context of digital imaging?

In the context of digital imaging, a pixel is defined as an individual square in the matrix. Each pixel represents the smallest unit of an image and contains information about color and brightness at that specific point. When these pixels are combined in a grid or matrix, they create a complete image that can be displayed on screens or printed.

Understanding the concept of a pixel is essential for grasping how digital images are processed and displayed. Each pixel's characteristics contribute to the overall quality and detail of an image. The higher the number of pixels in an image, the more detail it can display, which is why image resolution—often measured in pixels—is a critical factor in digital imaging technologies.
