Today we take for granted color resolutions of 24 bits per pixel (which potentially allows up to 16,777,216 colors and true photographic quality). But back then, 256 colors seemed like such a luxury.

The 10-bit color output enables 1024 gradations per color channel, a significant increase from 256 with 8-bit depth on previous iMacs. 30 bit pixel depth — 10 bit for each RGB color (Image ...

In the case of an image, bits in a 1MB file would assign a color to each pixel, making it readable to the human eye. In the case of a cryptographic function like SHA-256 (Secure Hash Algorithm 256-bit ...
