How is an image represented in binary?

Answer 1

An image is represented in binary as a grid of pixels, where each pixel's color is defined by a combination of binary values. Typically, colors are encoded using the RGB (Red, Green, Blue) color model, where each color channel is represented by a specific number of bits (commonly 8 bits), allowing for 256 different intensity levels per channel. For instance, a standard 24-bit image uses 8 bits for each of the three color channels, resulting in over 16 million possible colors. The entire image is stored as a long sequence of binary numbers corresponding to the pixel values, which can be processed by computers.
