While most downloaded files initially included restrictions on their use, enforced by FairPlay, Apple's implementation of digital rights management, iTunes later initiated a shift into selling DRM-free music in most countries, marketed as iTunes Plus.

* Digital Integrating Computer, a digital implementation of a Differential Analyzer

Because of its straightforward implementation in digital electronic circuitry using logic gates, the binary system is used internally by almost all modern computers and computer-based devices such as mobile phones.

These DNAzymes are used to build logic gates analogous to digital logic in silicon ; however, DNAzymes are limited to 1 -, 2 -, and 3-input gates with no current implementation for evaluating statements in series.

As with other systems, ATSC depends on numerous interwoven standards, e. g. the EIA-708 standard for digital closed captioning, leading to variations in implementation.

In a later implementation, the metadata, which was in large part automatically extracted from the animation database, was encoded as a digital signal in the analog video.

* Wallace tree, hardware implementation of digital circuit that multiplies two integers

It differs from a digital signal, in which a continuous quantity is represented by a discrete function which can only take on one of a finite number of values.

This number connects to a computer at a local central office, which uses a voice synthesizer or digital samples to " speak " the phone number of the line calling in.

The large number of operations ( 2 < sup > 128 </ sup >) required to try all possible 128-bit keys is widely considered to be out of reach for conventional digital computing techniques for the foreseeable future.

In digital logic and computing, a counter is a device which stores ( and sometimes displays ) the number of times a particular event or process has occurred, often in relationship to a clock signal.

Many types of counter circuits are available as digital building blocks, for example a number of chips in the 4000 series implement different counters.

They would start by selling computer modules as stand-alone devices that could be purchased separately and wired together to produce a number of different digital systems for lab use.

There are a number of different ways to receive digital television.

* Granularity: When a continuously variable analog value is represented in digital form there is always a decision as to the number of symbols to be assigned to that value.

In late 2005, interest in digital 3-D stereoscopic projection has led to a new willingness on the part of theaters to co-operate in installing a limited number of 2K stereo installations to show Disney's Chicken Little in 3-D film.

The complexity of such a system is specified by its order N. N is often a constraint on the design of a transfer function since it specifies the number of reactive components in an analog circuit ; in a digital IIR filter the number of computations required is proportional to N.

It uses digital logic to count the number of cycles during a time interval established by a precision quartz time base.

Indeed, the observable universe is far too small to contain an ordinary digital representation of Graham's number, assuming that each digit occupies at least one Planck volume.

Displays for a small number of individual digits and / or fixed symbols ( as in digital watches and pocket calculators ) can be implemented with independent electrodes for each segment.

Currently all stations in the country are digital and the number of installed lines has reached 1, 179, 000 with around 33 telephones per 100 inh.

mLan was used in a number of Yamaha products, notably digital mixing consoles and the Motif synthesizer, and in third-party products such as the PreSonus FIREstation and the Korg Triton Studio.

These are methods to transfer a digital bit stream over an analog baseband channel ( a. k. a. lowpass channel ) using a pulse train, i. e. a discrete number of signal levels, by directly modulating the voltage or current on a cable.

Digital broadcasting permits higher-resolution television, but digital standard definition television in these countries continues to use the frame rate and number of lines of resolution established by the analog NTSC standard ; systems using the NTSC framerate and resolution ( such as DVDs ) are still referred to informally as " NTSC ".

Pixel counts can be expressed as a single number, as in a " three-megapixel " digital camera, which has a nominal three million pixels, or as a pair of numbers, as in a " 640 by 480 display ", which has 640 pixels from side to side and 480 from top to bottom ( as in a VGA display ), and therefore has a total number of 640 × 480 = 307, 200 pixels or 0. 3 megapixels.

A megapixel ( MP or Mpx ) is one million pixels, and is a term used not only for the number of pixels in an image, but to express the number of image sensor elements of digital cameras or the number of display elements of digital displays.

The first digital computers used machine-language programming to set up and access array structures for data tables, vector and matrix computations, and for many other purposes.
