What is characteristic of 8-bit imagery?

An 8-bit imagery is defined by its ability to represent a specific range of brightness values. In an 8-bit image, each pixel is assigned a value ranging from 0 to 255, which corresponds to 256 different brightness levels. This allows for smooth gradients and a variety of shades within the image, making it suitable for grayscale representations and simple color images through indexed color palettes.

The other options do not accurately describe characteristics of 8-bit imagery. While an 8-bit image can display colored pixels, it is not limited exclusively to color, as it can also represent grayscale images. High-resolution images and data compression do not inherently relate to the 8-bit depth; images can be high-resolution or compressed regardless of their bit depth. Similarly, while an 8-bit image can represent binary images (black and white), it also can encompass a wide range of colors and shades beyond just black and white.
