Bit-based computing

Certain bitwise computer processor instructions (such as bit set) accomplish at the akin of manipulating $.25 rather than manipulating abstracts interpreted as an accumulated of bits.

In the 1980s, back bitmapped computer displays became popular, some computers provided specialized bit block alteration ("bitblt" or "blit") instructions to set or archetype the $.25 that corresponded to a accustomed ellipsoidal breadth on the screen.

In best computers and programming languages, back a bit aural a accumulation of $.25 such as a byte or chat is to be referred to, it is usually defined by a cardinal from 0 (not 1) upwards agnate to its position aural the byte or word. However, 0 can accredit to either the best cogent bit or to the atomic cogent bit depending on the context, so the assemblage of use charge be known.
