Both the miniaturization and standardization of CPUs have increased the presence of digital devices in modern life far beyond the limited application of dedicated computing machines.

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 computing, memory refers to the physical devices used to store programs ( sequences of instructions ) or data ( e. g. program state information ) on a temporary or permanent basis for use in a computer or other digital electronic device.

Advances in computing power and software for manipulation of digital media have dramatically affected the way computer music is generated and performed.

It is most commonly used in computing and electronics, especially where real-world information is converted to binary numeric form as in digital audio and digital photography.

Even though digital signals are generally associated with the binary electronic digital systems used in modern electronics and computing, digital systems are actually ancient, and need not be binary or electronic.

A digital IIR filter can generally approximate a desired filter response using less computing power than a FIR filter, however this advantage is more often unneeded given the increasing power of digital processors.

Thus the complexity of a digital filter and the computing time involved, grows inversely with, placing a higher cost on filter functions which better approximate the desired behavior.

His work, as important as it was in its own right, was a part of a continuum of progress in communications and electronics that since his time has brought forward color television, the personal computer, the Internet, cable and satellite radio and TV, personal mobile phones, audio, video and computing, digital stereo radio on both the medium wave and VHF-FM bands, and digital high definition television on VHF, UHF, cable and satellite.

Each hexadecimal digit represents four binary digits ( bits ), and the primary use of hexadecimal notation is a human-friendly representation of binary-coded values in computing and digital electronics.

Digital electronic computers like the ENIAC spelled the end for most analog computing machines, but hybrid analog computers, controlled by digital electronics, remained in substantial use into the 1950s and 1960s, and later in some specialized applications.

* The T interface is a serial interface between a computing device and a terminal adapter, which is the digital equivalent of a modem.

In computing, JPEG ( ) is a commonly used method of lossy compression for digital photography ( image ).

Usually, counter circuits are digital in nature, and count in natural binary.

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

Sometimes digital buses in electronic systems are used to convey quantities that can only increase or decrease by one at a time, for example the output of an event counter which is being passed between clock domains or to a digital-to-analog converter.

Burroughs even had another Haydu tube that could operate as a digital counter and directly drive a Nixie tube for display.

This produces a weak rotating magnetic field that is picked up by a ( sometimes separate ) inductor, amplified electronically, and fed to a digital frequency counter whose output is typically scaled and displayed directly as field strength or output as digital data.

These are produced by a digital counter such as the 82C53 chip.

In anticipation of Biggio's reaching 3, 000 hits, the Astros installed a digital counter just left of center field displaying his current hit total.

Just as two different musical notes played together create a beat note at the difference in frequency between them, so these two radio signals are mixed to create a " beat " signal ( called a heterodyne ) and an electrical circuit then measures this frequency using a digital counter and displays the number on a digital display as the object's speed.

These are typically digital counters that either increment or decrement at a fixed frequency, which is often configurable, and which interrupt the processor when reaching zero, or alternatively a counter with a sufficiently large word size that it will not reach its counter limit before the end of life of the system.
