8-bit color, with three bits of red, three bits of green, and two bits of blue. In order to turn a true color 24-bit image into an 8-bit image, the image must go through a process called color quantization. Color quantization is the process of creating a color map for a less color dense image from a more dense image.
The attribute byte associated with every 8×8 pixel cell comprises (from LSB to MSB): three bits for the background color; three bits for the foreground color; one bit for the bright variant for both, and one bit for the flashing effect (alternate foreground and background colors every 0.32 seconds).
The vertical resolution is usually a multiple of 8 or 16 pixels due to most video codecs processing pixels on such sized blocks. A widescreen FHD video can be 1920 × 800 for a 12∶5 ratio or 1920 × 1040 for roughly 1.85 × 1 , for instance.
This is the highest resolution that generally can be displayed on analog computer monitors (most CRTs), and the highest resolution that most analogue video cards and other display transmission hardware (cables, switch boxes, signal boosters) are rated for (at 60 Hz refresh). 24-bit colour requires 9 MB of video memory (and transmission ...
Visiting card of Johann van Beethoven, brother of Ludwig van Beethoven. A visiting card, also called a calling card, was a small, decorative card that was carried by individuals to present themselves to others. It was a common practice in the 18th and 19th century, particularly among the upper classes, to leave a visiting card when calling on ...

An 8-bit register can store 2 8 different values. The range of integer values that can be stored in 8 bits depends on the integer representation used. With the two most common representations, the range is 0 through 255 (2 8 − 1) for representation as an binary number, and −128 (−1 × 2 7) through 127 (2 7 − 1) for representation as two's complement.
The highest display resolution of any mode was 640 × 200, and the highest color depth supported was 4-bit (16 colors). The CGA card could be connected either to a direct-drive CRT monitor using a 4-bit digital RGBI interface, such as the IBM 5153 color display, or to an NTSC-compatible television or composite video monitor via an RCA connector ...
