DVD

DVD ( "digital versatile disc" or "digital video disc") is a digital optical disc storage format invented and developed by Philips, Sony, Toshiba, and Panasonic in 1995. The medium can store any kind of digital data and is widely used for software and other computer files as well as video programs watched using DVD players. DVDs offer higher storage capacity than compact discs while having the same dimensions.

Pre-recorded DVDs are mass-produced using molding machines that physically stamp data onto the DVD. Such discs are a form of DVD-ROMs, because data can only be read and not written or erased. Blank recordable DVD discs (DVD-R and DVD+R) can be recorded once using a DVD recorder and then function as a DVD-ROM. Rewritable DVDs (DVD-RW, DVD+RW, and DVD-RAM) can be recorded and erased many times.

DVDs are used in DVD-Video consumer digital video format and in DVD-Audio consumer digital audio format as well as for authoring DVD discs written in a special AVCHD format to hold high definition material (often in conjunction with AVCHD format camcorders). DVDs containing other types of information may be referred to as DVD data discs.

Martial arts

Martial arts are codified systems and traditions of combat practices, which are practiced for a variety of reasons: as self-defense, military and law enforcement applications; as competition, physical fitness, mental and spiritual development; as well as entertainment and the preservation of a nation's Intangible cultural heritage.

Although the term martial art has become associated with the fighting arts of eastern Asia, it originally referred to the combat systems of Europe as early as the 1550s. The term is derived from Latin, and means "arts of Mars", the Roman god of war. Some authors have argued that fighting arts or fighting systems would be more appropriate on the basis that many martial arts were never "martial" in the sense of being used or created by professional warriors.

Variation and scope

Martial arts may be categorized along a variety of criteria, including:

Spetsnaz

Spetsnaz (Russian: спецназ; IPA: [spʲɪt͜s'nas]), abbreviation for Войска специального назначения, tr. Voyska specialnogo naznacheniya pronounced [vɐjsˈka spʲɪt͡sɨˈalʲnəvə nəznɐˈt͜ɕenʲɪjə] (English: Special Purpose Forces or Special Purpose Military Units), is an umbrella term for special forces in Russian and is used in numerous post-Soviet states. Historically, the term referred to special military units controlled by the military intelligence service GRU (Spetsnaz GRU). It also describes special purpose units, or task forces of other ministries (such as the Ministry of Emergency Situations' special rescue unit) in post-Soviet countries.

As Spetsnaz is a Russian term it is typically associated with the special forces units of Russia, but other post-Soviet states often refer to their special forces by the term as well since they inherited their special purpose units from the now-defunct Soviet security agencies. The 5th spetsnaz Brigade of Belarus or the Alpha group of the Security Service of Ukraine are both such examples of non-Russian Spetsnaz forces.
