Federal Standard 1037CFederal Standard 1037C, titled Telecommunications: Glossary of Telecommunication Terms, is a United States Federal Standard issued by the General Services Administration pursuant to the Federal Property and Administrative Services Act of 1949, as amended.
TypesettingTypesetting is the composition of text for publication, display, or distribution by means of arranging physical type (or sort) in mechanical systems or glyphs in digital systems representing characters (letters and other symbols). Stored types are retrieved and ordered according to a language's orthography for visual display. Typesetting requires one or more fonts (which are widely but erroneously confused with and substituted for typefaces).
PaperPaper is a thin sheet of matted cellulosefibers. Largely derived from lignocellulose, paper is created from a pulp dissolved into a slurry that is drained and dried into sheets. Different types of paper are defined by constituent fiber, paper pulp, sizing, coating, paper size, paper density and grammage.
TeleprinterA teleprinter (teletypewriter, teletype or TTY) is an electromechanical device used to send and receive typed messages through various communications channels, in both point-to-point and point-to-multipoint configurations. Initially, teleprinters were used in telegraphy. Electrical telegraphy had been developed decades earlier in the late 1830s and 1840s, then using simpler Morse key equipment and telegraph operators.
Punched tapePunched tape or perforated paper tape is a form of data storage that consists of a long strip of paper through which small holes are punched. It was developed from and was subsequently used alongside punched cards, the difference being that the tape is continuous. Punched cards, and chains of punched cards, were used for control of looms in the 18th century. Use for telegraphy systems started in 1842.

DataData ( , US also ) is a collection of discrete or continuous values that conveys information, describing the quantity, quality, fact, statistics, other basic units of meaning, or simply sequences of symbols that may be further interpreted formally. A datum, data value or data point is an individual value in a collection of data.
Magnetic tapeMagnetic tape is a medium for magnetic storage made of a thin, magnetizable coating on a long, narrow strip of plastic film. It was developed in Germany in 1928, based on the earlier magnetic wire recording from Denmark. Devices that use magnetic tape can record and play back audio, visual, and digital computer data. Magnetic tape revolutionized sound recording and reproduction and broadcasting.Data processingData processing is the collection and manipulation of digital data to produce meaningful information. Data processing is a form of information processing, which is the modification (processing) of information in any manner detectable by an observer.
Computer securityProtection of computer systems from information disclosure, theft or damageComputer security (also cybersecurity, digital security, or information technology (IT) security) is a subdiscipline within the field of information security.
