Digital Dark Age
The digital dark age is a lack of historical information in the digital age as a direct result of outdated file formats, software, or hardware that becomes corrupt, scarce, or inaccessible as technologies evolve and data decays. Future generations may find it difficult or impossible to retrieve electronic documents and multimedia, because they have been recorded in an Obsolescence, obsolete and obscure file format, or on an obsolete physical medium; for example, floppy disks. The name derives from the term Dark Ages (historiography), ''Dark Ages'' in the sense that there could be a relative lack of records in the digital age as documents are transferred to digital formats and original copies are lost. An early mention of the term was at a conference of the International Federation of Library Associations and Institutions (IFLA) in 1997. The term was also mentioned in 1998 at the Time and Bits conference, which was co-sponsored by the Long Now Foundation and the Getty Conservation ...

Open Standard
An open standard is a standard that is openly accessible and usable by anyone. It is also a common prerequisite that open standards use an open license that provides for extensibility. Typically, anybody can participate in their development due to their inherently open nature. There is no single definition, and interpretations vary with usage. Examples of open standards include the GSM, 4G, and 5G standards that allow most modern mobile phones to work world-wide. Definitions The terms ''open'' and ''standard'' have a wide range of meanings associated with their usage. There are a number of definitions of open standards which emphasize different aspects of openness, including the openness of the resulting specification, the openness of the drafting process, and the ownership of rights in the standard. The term "standard" is sometimes restricted to technologies approved by formalized committees that are open to participation by all interested parties and operate on a consensus basis ...

PDF/A
PDF/A is an International Organization for Standardization, ISO-standardized version of the Portable Document Format (PDF) specialized for use in the archive, archiving and long-term digital preservation, preservation of electronic documents. PDF/A differs from PDF by prohibiting features unsuitable for long-term archiving, such as font linking (as opposed to font embedding) and encryption. The ISO requirements for PDF/A file viewers include color management guidelines, support for embedded fonts, and a user interface for reading embedded annotations. Standards Background PDF is a standard for encoding documents in an "as printed" form that is portable between systems. However, the suitability of a PDF file for archival preservation depends on options chosen when the PDF is created: most notably, whether to embed the necessary fonts for rendering the document; whether to use encryption; and whether to preserve additional information from the original document beyond what is ...

Submarine
A submarine (often shortened to sub) is a watercraft capable of independent operation underwater. (It differs from a submersible, which has more limited underwater capability.) The term "submarine" is also sometimes used historically or informally to refer to remotely operated vehicles and Autonomous underwater vehicle, robots, or to medium-sized or smaller vessels (such as the midget submarine and the wet sub). Submarines are referred to as ''boats'' rather than ''ships'' regardless of their size. Although experimental submarines had been built earlier, submarine design took off during the 19th century, and submarines were adopted by several navies. They were first used widely during World War I (1914–1918), and are now used in many navy, navies, large and small. Their military uses include: attacking enemy surface ships (merchant and military) or other submarines; aircraft carrier protection; Blockade runner, blockade running; Ballistic missile submarine, nuclear deterrenc ...

Encryption
In Cryptography law, cryptography, encryption (more specifically, Code, encoding) is the process of transforming information in a way that, ideally, only authorized parties can decode. This process converts the original representation of the information, known as plaintext, into an alternative form known as ciphertext. Despite its goal, encryption does not itself prevent interference but denies the intelligible content to a would-be interceptor. For technical reasons, an encryption scheme usually uses a pseudo-random encryption Key (cryptography), key generated by an algorithm. It is possible to decrypt the message without possessing the key but, for a well-designed encryption scheme, considerable computational resources and skills are required. An authorized recipient can easily decrypt the message with the key provided by the originator to recipients but not to unauthorized users. Historically, various forms of encryption have been used to aid in cryptography. Early encryption ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
LaserDisc
LaserDisc (LD) is a home video format and the first commercial optical disc storage medium. It was developed by Philips, Pioneer Corporation, Pioneer, and the movie studio MCA Inc., MCA. The format was initially marketed in the United States in 1978 under the name DiscoVision, a brand used by MCA. As Pioneer took a greater role in its development and promotion, the format was rebranded LaserVision. While the LaserDisc brand originally referred specifically to Pioneer's line of players, the term gradually came to be used generically to refer to the format as a whole, making it a genericized trademark. The discs typically have a diameter of , similar in size to the phonograph record. Unlike most later optical disc formats, LaserDisc is not fully Digital data, digital; it stores an analog video signal. Many titles featured Compact Disc Digital Audio, CD-quality digital audio, and LaserDisc was the first home video format to support surround sound. Its 425 to 440 horizontal lin ...

PC Migration
PC migration is the process of transferring the entire user environment (i.e. personal documents and settings) between two computer systems. The migration problem is often associated with the concept of total cost of ownership where the requirement to migrate information is considered a "cost" in purchasing a new PC, similar considerations exist for businesses upgrading hardware/software. PC migration is required whenever one needs to move to a new computer (i.e. purchasing new hardware), or upgrade to a new OS. Because of intrinsic differences and strong OS-hardware coupling, PC migration is considered to be a problem for both consumers and enterprises. Some PC migration software products are capable of transferring not just settings and data, but also applications. Sources for software that automates PC migration software include Laplink, Tranxition, and Swimage. Windows 10 does not any longer include a Windows transfer utility with the OS.

Domesday Book
Domesday Book ( ; the Middle English spelling of "Doomsday Book") is a manuscript record of the Great Survey of much of England and parts of Wales completed in 1086 at the behest of William the Conqueror. The manuscript was originally known by the Latin name , meaning "Book of Winchester, Hampshire, Winchester", where it was originally kept in the royal treasury. The ''Anglo-Saxon Chronicle'' states that in 1085 the king sent his agents to survey every shire in England, to list his holdings and dues owed to him. Written in Medieval Latin, it was Scribal abbreviation, highly abbreviated and included some vernacular native terms without Latin equivalents. The survey's main purpose was to record the annual value of every piece of landed property to its lord, and the resources in land, labour force, and livestock from which the value derived. The name "Domesday Book" came into use in the 12th century. Richard FitzNeal wrote in the ( 1179) that the book was so called because its de ...

BBC Domesday Project
The BBC Domesday Project was a partnership between Acorn Computers, Philips, Logica, and the BBC (with some funding from the European Commission's ESPRIT programme) to mark the 900th anniversary of the original ''Domesday Book'', an 11th-century census of England. It has been cited as an example of digital obsolescence on account of the physical medium used for data storage. This new multimedia edition of Domesday was compiled between 1984 and 1986 and published in 1986. It included a new "survey" of the United Kingdom, in which people, mostly school children, wrote about geography, history or social issues in their local area or just about their daily lives. This was linked with maps, and many colour photos, statistical data, video and "virtual walks". The project also incorporated professionally prepared video footage, virtual reality tours of major landmarks and other prepared datasets such as the 1981 census. Over a million people participated in the project, including chil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apollo 11
Apollo 11 was a spaceflight conducted from July 16 to 24, 1969, by the United States and launched by NASA. It marked the first time that humans Moon landing, landed on the Moon. Commander Neil Armstrong and Lunar Module pilot Buzz Aldrin landed the Lunar Module Eagle, Lunar Module ''Eagle'' on July 20, 1969, at 20:17 Coordinated Universal Time, UTC, and Armstrong became the first person to step onto the Moon's surface six hours and 39 minutes later, on July 21 at 02:56 UTC. Aldrin joined him 19 minutes later, and they spent about two and a quarter hours together exploring the site they had named Tranquility Base upon landing. Armstrong and Aldrin collected of lunar material to bring back to Earth as pilot Michael Collins (astronaut), Michael Collins flew the Command Module Columbia, Command Module ''Columbia'' in lunar orbit, and were on the Moon's surface for 21 hours, 36 minutes, before lifting off to rejoin ''Columbia''.
