Questions tagged [digital]

Digital usually refers to something using digits, particularly binary digits.

1. (of signals or data) Digital describes electronic technology that generates, stores, and processes data in terms of two states: positive and non-positive. Positive is expressed or represented by the number 1 and non-positive by the number 0. Thus, data transmitted or stored with digital technology is expressed as a string of 0's and 1's. Each of these state digits is referred to as a bit (and a string of bits that a computer can address individually as a group is a byte).

2. (of a clock or watch) A digital clock is a type of clock that displays the time digitally (i.e. in numerals or other symbols)

3. (of design or style) Digital Design or styles containing a set of graphically related glyphs, characters, or symbols. They are associated to everything from websites and computer-game graphics to special effects for movies.

4. (of media) Digital media are any media that are encoded in machine-readable formats. Digital media can be created, viewed, distributed, modified and preserved on digital electronics devices. Examples of digital media include software, digital images, digital video, video game, web pages and websites, including social media, data and databases, digital audio, such as MP3 and electronic books.
