No optimism is more baseless than that which believes that the high speed of modern digital computers allows for use of the crudest of methods in searching out a result.

Limitations with mp3-player DJing equipment has meant that only second generation equipment such as the IDJ2 or the Cortex Dmix-300 have the pitch control that alters tempo and allows for beatmatching on a digital music player.

This allows the DJ to make use of the beatmatching capabilities of the CDJ unit whilst playing digital music files from the mp3-player or other storage device.

The digital data on a CD begins at the center of the disc and proceeds toward the edge, which allows adaptation to the different size formats available.

A broadcaster may opt to use a standard-definition ( SDTV ) digital signal instead of an HDTV signal, because current convention allows the bandwidth of a DTV channel ( or " multiplex ") to be subdivided into multiple digital subchannels, ( similar to what most FM radio stations offer with HD Radio ), providing multiple feeds of entirely different television programming on the same channel.

Even if this process is more complex than analog processing and has a discrete value range, the application of computational power to digital signal processing allows for many advantages over analog processing in many applications, such as error detection and correction in transmission as well as data compression.

Enhanced Data rates for GSM Evolution ( EDGE ) ( also known as Enhanced GPRS ( EGPRS ), or IMT Single Carrier ( IMT-SC ), or Enhanced Data rates for Global Evolution ) is a digital mobile phone technology that allows improved data transmission rates as a backward-compatible extension of GSM.

While data reduction ( compression, be it lossy or lossless ) is a main goal of transform coding, it also allows other goals: one may represent data more accurately for the original amount of space – for example, in principle, if one starts with an analog or high-resolution digital master, an MP3 file of a given size should provide a better representation than a raw uncompressed audio in WAV or AIFF file of the same size.

Digital Pathology is an image-based information environment enabled by computer technology that allows for the management of information generated from a digital slide.

The use of these algorithms also allows the authenticity of a message to be checked by creating a digital signature of the message using the private key, which can then be verified by using the public key.

This, in conjunction with digital fire control / ballistic computers and digital communications, allows individual guns to disperse over a wide area and still deliver rounds on target simultaneously with the other guns in their battery.

This feature allows the user to choose favorite channels, making them easier and quicker to access ; this is handy with the wide range of digital channels on offer.

This allows the user to use just one remote to turn the TV on and off, adjust volume, or switch between digital and analog TV channels or between terrestrial and internet channels.

This allows the separation of analog and digital sections of a board or the inputs and outputs of amplifiers.

The same functionality which makes a debugger useful for eliminating bugs allows it to be used as a software cracking tool to evade copy protection, digital rights management, and other software protection features.

The protection of the private key is the idea behind the United States Department of Defense's Common Access Card ( CAC ), which never allows the key to leave the card and therefore necessitates the possession of the card in addition to the personal identification number ( PIN ) code necessary to unlock the card for permission to use it for encryption and digital signatures.

Conversion to a digital format allows convenient manipulation, storage, transmission and retrieval of an audio signal.

The Display Data Channel or DDC is a digital connection between a computer display and a graphics adapter that allows the display to communicate its specifications to the adapter.

FLAC (; Free Lossless Audio Codec ) is a codec ( compressor-decompressor or coder-decoder ) which allows digital audio to be losslessly compressed such that file size is reduced without any information being lost.

Use with a digital SLR allows metering and composition by trial and error, and is effectively free, so is a popular way to try pinhole photography.

The use of a click track allows for easier editing in a digital audio workstation ( DAW ) or music sequencer, since various parts can be easily quantized and moved around or spliced together without worrying about minute differences in timing.

Examples of these extensions include teletext, closed captioning, digital information regarding the show title, transmitting a set of reference colors that allows TV sets to automatically correct the hue mal-adjustments common with the NTSC color encoding system, etc.

The service allows users to make calls to landlines and moblie devices through the use of a computer.

The Xerox Alto was the first to use a graphical user interface. In computing, a graphical user interface ( GUI, commonly pronounced gooey ) is a type of user interface that allows users to interact with electronic devices using images rather than text commands.

Cardano invented several mechanical devices including the combination lock, the gimbal consisting of three concentric rings allowing a supported compass or gyroscope to rotate freely, and the Cardan shaft with universal joints, which allows the transmission of rotary motion at various angles and is used in vehicles to this day.

The narrative structure allows for this diversity through simple stylistic devices such as the principle of ring composition, familiar since the time of Homer, in which the introduction and conclusion of a story or sub-plot is signalled by the repetition of some formulaic statement, facilitating the reader's comprehension of stories within stories in a kind of ' Chinese-box technique '— a structure that has no resemblance to the nine books artificially created by Alexandrian scholars.

* USB hub, allows many USB devices to be connected to a single USB port

The concept of " formatting " in these devices allows the screen to be divided into clusters of contiguous character cells for which numerous " attributes " ( colour, highlighting, character set, protection from modification ) can be set.

The " rectangular shape " set, based on IEC 60617-12 and other early industry standards, has rectangular outlines for all types of gate and allows representation of a much wider range of devices than is possible with the traditional symbols.

This allows the scale, by comparing weights, to also compare masses, and gives it the distinction of being one of the oldest known devices capable of measuring mass.

It is a set of standard commands that allows electronic musical instruments, performance controllers, computers and related devices to communicate, as well as a hardware standard that guarantees compatibility between them.

The MIDI standard allows selection of 128 different programs, but devices can provide more by arranging their patches into banks of 128 programs each, and combining a program change message with a bank select message.

A MIDI merger is able to combine the input from multiple devices into a single stream, and allows multiple controllers to be connected to a single device.

A MIDI switcher allows switching between multiple devices, and eliminates the need to physically repatch cables.

This allows a single playing surface to target a number of different devices.

MIDI footswitches are commonly used to send MIDI program change commands to effects devices, but may be combined with pedals in a pedalboard that allows detailed programming of effects units.

Many instruments also include a SysEx ID setting, which allows two devices of the same model to be addressed independently while connected to the same system.

GM2 is the basis of the instrument selection mechanism in Scalable Polyphony MIDI ( SP-MIDI ), a MIDI variant for low power devices that allows the device's polyphony to scale according to its processing power.

MIDI Show Control ( MSC ) is a set of SysEx commands which allows sequencing and remote cueing of show control devices such as lighting, music and sound playback, and motion control systems.

The Downloadable Sounds ( DLS ) specification was ratified in 1997, and allows mobile devices and computer sound cards to expand their wavetables with sound sets that can be automatically downloaded.

MTC allows the synchronisation of a sequencer or DAW with other devices that can synchronise to MTC or for these devices to ' slave ' to a tape machine that is striped with SMPTE.

Because the QS regulation covers a broad spectrum of devices and production processes, it allows some leeway in the details of quality system elements.

* Square ( application ), a service and device that allows credit card payments to be accepted through mobile devices

Data are transferred between the application's buffer and the disk using DMA, which allows access to the full I / O bandwidth of the underlying disk devices.

IEEE 802. 1aq ( Shortest Path Bridging SPB ) allows all paths to be active with multiple equal cost paths, provides much larger layer 2 topologies ( up to 16 million compared to the 4096 VLANs limit ), faster convergence times, and improves the use of the mesh topologies through increase bandwidth and redundancy between all devices by allowing traffic to load share across all paths of a mesh network.
