What is a digital computer?

Digital computer, any of a class of devices capable of solving problems by processing information in discrete form. It operates on data, including magnitudes, letters, and symbols, that are expressed in binary code—i.e., using only the two digits 0 and 1.
A.

What is the difference between analog and digital?

Viewed from afar, the wave function below may seem smooth and analog, but when you look closely there are tiny discrete steps as the signal tries to approximate values: That's the big difference between analog and digital waves. Analog waves are smooth and continuous, digital waves are stepping, square, and discrete.
  • What are the advantages of a digital signal?

    Advantages of digital signals. Digital signals carry more information per second than analogue signals. This is the same whether optical fibres, cables or radio waves are used. Digital signals maintain their quality over long distances better than analogue signals.
  • What is the difference between digital and analog camera?

    Generally speaking, the difference in image quality is all based upon whether the camera system is digital or analog. A very brief crash course on analog vs digital cameras/signals. Analog cameras carry their signal over coaxial cable. Your phone probably has a higher resolution than analog cameras!
  • What is a digital system?

    Digital systems represent information using a binary system, where data can assume one of only two possible values: zero or one. • Appropriate for implementation in electronic circuitry, where values are characterized by the absence/presence of an electrical current flow.
B.

What is the use of analog computer?

An analog computer or analogue computer is a form of computer that uses the continuously changeable aspects of physical phenomena such as electrical, mechanical, or hydraulic quantities to model the problem being solved.
  • What is analog computer simple definition?

    Definition of analog computer. : a computer that operates with numbers represented by directly measurable quantities (such as voltages or rotations) — compare digital computer, hybrid computer.
  • What is the difference between analog and digital signals?

    Viewed from afar, the wave function below may seem smooth and analog, but when you look closely there are tiny discrete steps as the signal tries to approximate values: That's the big difference between analog and digital waves. Analog waves are smooth and continuous, digital waves are stepping, square, and discrete.
  • What is the electronic digital computer?

    In computer science, a digital electronic computer is a computer machine which is both an electronic computer and a digital computer. Examples of a digital electronic computers include the IBM PC, the Apple Macintosh as well as modern smartphones.
