Data transmission is utilized in computer networking equipment such as modems ( 1940 ), local area networks ( LAN ) adapters ( 1964 ), repeaters, hubs, microwave links, wireless network access points ( 1997 ), etc.

The Meta Data Repository-created by the non-profit RAND Corporation and sponsored by the National Institute on Aging at the National Institutes of Health-provides access to meta data for these questions as well as links to obtain respondent data from the originating surveys.

* PDBsum has links to three-dimensional structures of various alcohol dehydrogenases contained in the Protein Data Bank

Data structures are implemented in a programming language as data types and the references ( e. g. relationships, links and pointers ) and operations that are possible with them.

Symbolic links were already present by 1978 in mini-computer operating systems from DEC and Data General's RDOS.

Mad Data, with the permission of Dongleware, has produced an official freeware game with the name " Oxyd extra v2. 0 " ( see external links below ).

Data bases with thousands of links all over the world.

MTP Level 1 is described in ITU-T Recommendation Q. 702, and provides the Signalling Data Link functional level for narrowband signalling links.

On Unix and DOS, B32 emulated all commonly used system calls of Data General's AOS / VS and RDOS operating systems, including implementing its own symbolic links on SCO Xenix and DOS.

* Data links

When it upgraded to CIDIN ( Common ICAO Civil Aviation Organization Data Interchange Network ), it was upgraded to X. 25 links at much higher data rates.

* 3M Fluorinert Electronic Liquids – contains links to Material Safety Data Sheets and Product Information Sheets

* Tactical Data Link The family of tactical data links

Digital Data Communications Message Protocol ( DDCMP ) is a communications protocol devised by Digital Equipment Corporation in 1974 to allow communication over point-to-point network links for the company's DECnet Phase I network protocol.

Data transmission may make use of encrypted RTTY, use Link-11 for radar tracking data, or use of Automatic link establishment modes to set up communication links automatically.

However, in the early years of the mission, long before the advent of the World Wide Web and fast global data transmission links, access to the archive required a visit in person to one of two Regional Data Analysis Facilities ( RDAFs ), one at the University of Colorado and the other at GSFC.

Data communications protocols of the period were not efficient over satellite links.

The Joint Data Network ( JDN ) is an interconnected network of JTIDS – based systems, which links air and missile defense command and control and weapons systems across United States armed forces.

Data on such comparisons together with data on the effect of light intensity are given in Table 1.

Also in case of Single Instructions Multiple Data — a case when a lot of data from the same type has to be processed, modern processors can disable parts of the pipeline so that when a single instruction is executed many times, the CPU skips the fetch and decode phases and thus greatly increases performance on certain occasions, especially in highly monotonous program engines such as video creation software and photo processing.

Until that time, software was bundled with the hardware by Original equipment manufacturers ( OEMs ) such as Data General, Digital Equipment and IBM.

Operations such as these, and even more elaborate operations can also be performed in computer music programming languages such as Max / MSP, SuperCollider, Csound, Pure Data ( Pd ), Keykit, and ChucK.

Several such tailorings are collected in Common Locale Data Repository.

The first successful calculators with LCDs were manufactured by Rockwell International and sold from 1972 by other companies under such names as: Dataking LC-800, Harden DT / 12, Ibico 086, Lloyds 40, Lloyds 100, Prismatic 500 ( aka P500 ), Rapid Data Rapidman 1208LC.

:: Data warehouses archive data from operational databases and often from external sources such as market research firms.

Data manipulation languages are typically intended to describe what is needed in a single such step.

Interest in a standard began to grow, and Charles Bachman, author of one such product, the Integrated Data Store ( IDS ), founded the " Database Task Group " within CODASYL, the group responsible for the creation and standardization of COBOL.

Data structures provide a means to manage huge amounts of data efficiently, such as large databases and internet indexing services.

Nevertheless, several libraries and some writers, such as Aho, Hopcroft, and Ullman in their textbook Data Structures and Algorithms, spell it dequeue.

Originally, electronic commerce was identified as the facilitation of commercial transactions electronically, using technology such as Electronic Data Interchange ( EDI ) and Electronic Funds Transfer ( EFT ).

For instance, standards for encoding data, e. g., country codes, but more significantly some encryption standards, such as the Data Encryption Standard ( FIPS 46-3 ) and the Advanced Encryption Standard ( FIPS 197 )

* Data management 4GLs such as SAS, SPSS and Stata provide sophisticated coding commands for data manipulation, file reshaping, case selection and data documentation in the preparation of data for statistical analysis and reporting.

Several front-ends have been built for it, such as Xxgdb, Data Display Debugger ( DDD ), Nemiver, KDbg, Xcode debugger, GDBtk / Insight and the HP Wildebeest Debugger GUI ( WDB GUI ).

Some industry sectors have policies, procedures, standards and guidelines that must be followed – the Payment Card Industry ( PCI ) Data Security Standard required by Visa and MasterCard is such an example.

* UK Data Protection Act 1998 makes new provisions for the regulation of the processing of information relating to individuals, including the obtaining, holding, use or disclosure of such information.

At the Data Link Layer, multicast describes one-to-many distribution such as Ethernet multicast addressing, Asynchronous Transfer Mode ( ATM ) point-to-multipoint virtual circuits ( P2MP ) or Infiniband multicast.

Most modern PLCs can communicate over a network to some other system, such as a computer running a SCADA ( Supervisory Control And Data Acquisition ) system or web browser.

Most such methods do rely on comparisons between the sequence to be predicted and sequences of known structure in the Protein Data Bank and thus account for environment indirectly, assuming the target and template sequences share similar cellular contexts.

The Standards Board ensures that coherent regulations are developed in areas such as Electronic Data Interchange ( EDI ), mail encoding, postal forms and meters.

Important well known and popular techniques, almost universally used in industry, such as Data Flow Diagrams and Structure Charts were not included in the specification.

# ATM Layer correspond roughly to the OSI Data Link Layer

Data Link Layer and Physical Layer Specifications ".

The services and protocols specified in IEEE 802 map to the lower two layers ( Data Link and Physical ) of the seven-layer OSI networking reference model.

In fact, IEEE 802 splits the OSI Data Link Layer into two sub-layers named Logical Link Control ( LLC ) and Media Access Control ( MAC ), so that the layers can be listed like this:

Switched Ethernet has been for some time the most common Data Link Layer and Physical Layer implementation for local area networks.

Each wireless technology is defined by a standard that describes unique functions at both the Physical and the Data Link layers of the OSI Model.

ADCCP is an ANSI standard, X3. 66, derived from IBM's Synchronous Data Link Control ( SDLC ) protocol, and is functionally equivalent to the ISO High-Level Data Link Control ( HDLC ) standard.

These protocols reside in the Data Link or Transport Layers of the OSI model.

CSMA / CA is a protocol that operates in the Data Link Layer ( Layer 2 ) of the OSI model.

* At the Data Link Layer: The IEEE 802. 2 protocol at the Logical Link Control sublayer of the data link layer may provide both connectionless and connection-oriented services.

In civil aviation, a data-link system ( known as Controller Pilot Data Link Communications ) is used to send information between aircraft and air traffic controllers when an aircraft is too far from the ATC to make voice radio communication and radar observations possible.

Note 2: Flag sequences are used in bit-oriented protocols, such as Advanced Data Communication Control Procedures ( ADCCP ), Synchronous Data Link Control ( SDLC ), and High-Level Data Link Control ( HDLC ).
