Computer Science for IGCSE & O level - Data Representation (Section 11 - No. 42)

If an image is 1920 pixels wide and 1080 pixels high and has a color depth of 8 bits (256 colors), what is its uncompressed size in bytes?

1920 * 1080 bytes

1920 * 1080 * 8 bytes

1920 * 1080 / 8 bytes

(1920 * 1080 * 8) / 1024 bytes

With 8 bits per pixel, you need 1 byte per pixel (8 bits/8 bits per byte = 1 byte/pixel).
