Character (computing) of the “basic execution character set” and (in newer C standards) UTF-8 code units which implies a minimum size of 8 bits. The exact number of bits can be checked via codice_2 macro. By far the most common size is 8 bits, and the POSIX standard "requires" it to be 8 bits. Since Unicode requires at least 21 bits to store a single code point, it is usually impossible to store one inside a single codice_1; instead a variable-length encoding such as UTF-8 must be used. Unfortunately, the fact that a character was historically stored in a single byte led
Packed pixel Packed pixel In packed pixel or chunky framebuffer organization, the bits defining each pixel are grouped together. For example, if there are 16 bits per pixel, each pixel is represented in two consecutive (contiguous) 8-bit bytes in the framebuffer (a.k.a. screen buffer). If there are 4 bits per pixel (16 colors), each frame buffer byte defines two pixels, one in each nibble. The latter example is as opposed to storing perhaps half of the bits—2 bits—for each of four pixels in one byte and the other two bits for each of those four pixels in another byte or bytes. It
