[|Zaid Alhassan] Definition: || # Relating to or using signals or information represented by discrete values (digits) of a physical quantity, such as voltage or magnetic...: "digital TV" Source: [|Dictionary .com]) 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). Describes the use of digital pulses, signals or values to represent data in computer graphics, [|telecommunications] systems and word processing. Unlike computers, humans perceive information in analog. We capture auditory and visual signals as a continuous stream. Digital devices, on the other hand, estimate this information using ones and zeros. The rate of this estimation, called the "sampling rate," combined with how much information is included in each sample (the bit depth), determines how accurate the digital estimation is. Computers are digital machines because they can only read information as on or off -- 1 or 0. This method of computation, also known as the binary system, may seem rather simplistic, but can be used to represent incredible amounts of data. CDs and DVDs can be used to store and play  back high-quality sound and video even though they consist entirely of ones and zeros.
