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The digital dark age is a lack of historical information in the digital age as a direct result of outdated file formats, software, or hardware that becomes corrupt, scarce, or inaccessible as technologies evolve and data decay. Future generations may find it difficult or impossible to retrieve electronic documents and multimedia, because they have been recorded in an obsolete and obscure file format, or on an obsolete physical medium, for example, floppy disks. The name derives from the term ''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 Institute. Proprietary and obsolete ...

NASA
The National Aeronautics and Space Administration (NASA ) is an independent agencies of the United States government, independent agency of the US federal government responsible for the civil List of government space agencies, space program, aeronautics research, and outer space, space research. NASA was National Aeronautics and Space Act, established in 1958, succeeding the National Advisory Committee for Aeronautics (NACA), to give the U.S. space development effort a distinctly civilian orientation, emphasizing peaceful applications in space science. NASA has since led most American space exploration, including Project Mercury, Project Gemini, the 1968-1972 Apollo program, Apollo Moon landing missions, the Skylab space station, and the Space Shuttle. NASA supports the International Space Station and oversees the development of the Orion (spacecraft), Orion spacecraft and the Space Launch System for the crewed lunar Artemis program, Commercial Crew Program, Commercial Crew ...

Digital Rights Management
Digital rights management (DRM) is the management of legal access to digital content. Various tools or technological protection measures (TPM) such as access control technologies can restrict the use of proprietary hardware and copyrighted works. DRM technologies govern the use, modification, and distribution of copyrighted works (such as software and multimedia content), as well as systems that enforce these policies within devices. Laws in many countries criminalize the circumvention of DRM, communication about such circumvention, and the creation and distribution of tools used for such circumvention. Such laws are part of the United States' Digital Millennium Copyright Act (DMCA), and the European Union's Information Society Directive (the French DADVSI is an example of a member state of the European Union implementing the directive). DRM techniques include licensing agreements and encryption. The industry has expanded the usage of DRM to various hardware products, such ...

Submarine
A submarine (or sub) is a watercraft capable of independent operation underwater. It differs from a submersible, which has more limited underwater capability. The term is also sometimes used historically or colloquially to refer to remotely operated vehicles and robots, as well as medium-sized or smaller vessels, such as the midget submarine and the wet sub. Submarines are referred to as ''boats'' rather than ''ships'' irrespective of their size. Although experimental submarines had been built earlier, submarine design took off during the 19th century, and they were adopted by several navies. They were first widely used during World War I (1914–1918), and are now used in many navies, large and small. Military uses include attacking enemy surface ships (merchant and military) or other submarines, and for aircraft carrier protection, blockade running, nuclear deterrence, reconnaissance, conventional land attack (for example, using a cruise missile), and covert insertion o ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, massa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Encryption
In cryptography, encryption is the process of encoding information. This process converts the original representation of the information, known as plaintext, into an alternative form known as ciphertext. Ideally, only authorized parties can decipher a ciphertext back to plaintext and access the original information. 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 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 techniques were often used in mil ...

LaserDisc
The LaserDisc (LD) is a home video format and the first commercial optical disc storage medium, initially licensed, sold and marketed as MCA DiscoVision (also known simply as "DiscoVision") in the United States in 1978. Its diameter typically spans . Unlike most optical disc standards, LaserDisc is not fully digital, and instead requires the use of analog video signals. Although the format was capable of offering higher-quality video and audio than its consumer rivals— VHS and Betamax videotape—LaserDisc never managed to gain widespread use in North America, largely due to high costs for the players and the inability to record TV programmes. It eventually did gain some traction in that region and became somewhat popular in the 1990s. It was not a popular format in Europe and Australia. By contrast, the format was much more popular in Japan and in the more affluent regions of Southeast Asia, such as Hong Kong, Singapore and Malaysia, and was the prevalent rental video me ...

PC Migration
PC migration is the process of transferring the entire user environment (e.g. 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 by order of King William I, known as William the Conqueror. The manuscript was originally known by the Latin name ''Liber de Wintonia'', meaning "Book of 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 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, manpower, and livestock from which the value derived. The name "Domesday Book" came into use in the 12th century. Richard FitzNeal wrote in the '' Dialogus de Scaccario'' ( 1179) that the bo ...

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 (July 16–24, 1969) was the American spaceflight that first landed humans on the Moon. Commander Neil Armstrong and lunar module pilot Buzz Aldrin landed the Apollo Lunar Module ''Eagle'' on July 20, 1969, at 20:17 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 flew the Command Module ''Columbia'' in lunar orbit, and were on the Moon's surface for 21 hours, 36 minutes before lifting off to rejoin ''Columbia''. Apollo 11 was launched by a Saturn V rocket from Kennedy Space Center on Merritt Island, Florida, on July 16 at 13:32 UTC, and it was the fifth crewed mission of NASA's Apollo program. The Apollo spacecraft had ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
