6 Hidden Features in Windows 10. Quantum thinking: Cats to computers. Secure Digital. Type of memory storage for portable devices Secure Digital, officially abbreviated as SD, is a proprietary non-volatile flash memory card format developed by the SD Association (SDA) for use in portable devices. The standard was introduced in August 1999 by joint efforts between SanDisk, Panasonic (Matsushita) and Toshiba as an improvement over MultiMediaCards (MMCs),[1] and has become the industry standard. The three companies formed SD-3C, LLC, a company that licenses and enforces intellectual property rights associated with SD memory cards and SD host and ancillary products.[2] The companies also formed the SD Association (SDA), a non-profit organization, in January 2000 to promote and create SD Card standards.[3] SDA today has about 1,000 member companies.
The SDA uses several trademarked logos owned and licensed by SD-3C to enforce compliance with its specifications and assure users of compatibility.[4] History[edit] 1999–2005: Creation and introduction of smaller formats[edit] Notes: Regin, new computer spying bug, discovered by Symantec. 23 November 2014Last updated at 13:32 ET Symantec researchers likened the bug to Stuxnet, a computer worm that targeted Iran's nuclear program A leading computer security company says it has discovered one of the most sophisticated pieces of malicious software ever seen.
Symantec says the bug, named Regin, was probably created by a government and has been used for six years against a range of targets around the world. Once installed on a computer, it can do things like capture screenshots, steal passwords or recover deleted files. Experts say computers in Russia, Saudi Arabia and Ireland have been hit most.
It has been used to spy on government organisations, businesses and private individuals, they say. Researchers say the sophistication of the software indicates that it is a cyber-espionage tool developed by a nation state. They also said it likely took months, if not years, to develop and its creators have gone to great lengths to cover its tracks. Sony tape smashes storage record. 5 May 2014Last updated at 08:33 ET Storage tapes like these are used by many firms to keep data for long periods Sony has developed a new storage tape that is able to hold up to 185 terabytes (TB) of data per cartridge. Created with the help of IBM, Sony's technology allows for tapes that can store the equivalent of 3,700 Blu-ray discs.
The tape hold 148 gigabits (Gb) per square inch - beating a record set in 2010 more than five times over. Storage tapes are typically used by businesses to hold huge amounts of data for a long time. Analysts IDC predict that by 2020, global data storage will amount to 40 trillion gigabytes - around 5,200 gigabytes per person. Using tape is a cheaper and more energy efficient method of storing data when compared to power-hungry large data centres full of hard drives. However, retrieving data from tape is a far slower process. 'Rapid recovery' Over a long time period, tape is considered the more reliable approach.
