In computing, a data segment (often denoted .data) is a portion of an object file or the corresponding virtual address space of a program that contains initialized static variables, that is, global variables and static local variables. The size of this segment is determined by the size of the values in the program's source code, and does not change at run time.
The data segment is read-write, since the values of variables can be altered at run time. This is in contrast to the read-only data segment (rodata segment or .rodata), which contains static constants rather than variables; it also contrasts to the code segment, also known as the text segment, which is read-only on many architectures. Uninitialized data, both variables and constants, is instead in the BSS segment.
Historically, to be able to support memory address spaces larger than the native size of the internal address register would allow, early CPUs implemented a system of segmentation whereby they would store a small set of indexes to use as offsets to certain areas. The Intel 8086 family of CPUs provided four segments: the code segment, the data segment, the stack segment and the extra segment. Each segment was placed at a specific location in memory by the software being executed and all instructions that operated on the data within those segments were performed relative to the start of that segment. This allowed a 16-bit address register, which would normally provide 64KiB (65536 bytes) of memory space, to access a 1MiB (1048576 bytes) address space.
DATA were an electronic music band created in the late 1970s by Georg Kajanus, creator of such bands as Eclection, Sailor and Noir (with Tim Dry of the robotic/music duo Tik and Tok). After the break-up of Sailor in the late 1970s, Kajanus decided to experiment with electronic music and formed DATA, together with vocalists Francesca ("Frankie") and Phillipa ("Phil") Boulter, daughters of British singer John Boulter.
The classically orientated title track of DATA’s first album, Opera Electronica, was used as the theme music to the short film, Towers of Babel (1981), which was directed by Jonathan Lewis and starred Anna Quayle and Ken Campbell. Towers of Babel was nominated for a BAFTA award in 1982 and won the Silver Hugo Award for Best Short Film at the Chicago International Film Festival of the same year.
DATA released two more albums, the experimental 2-Time (1983) and the Country & Western-inspired electronica album Elegant Machinery (1985). The title of the last album was the inspiration for the name of Swedish pop synth group, elegant MACHINERY, formerly known as Pole Position.
The word data has generated considerable controversy on if it is a singular, uncountable noun, or should be treated as the plural of the now-rarely-used datum.
In one sense, data is the plural form of datum. Datum actually can also be a count noun with the plural datums (see usage in datum article) that can be used with cardinal numbers (e.g. "80 datums"); data (originally a Latin plural) is not used like a normal count noun with cardinal numbers and can be plural with such plural determiners as these and many or as a singular abstract mass noun with a verb in the singular form. Even when a very small quantity of data is referenced (one number, for example) the phrase piece of data is often used, as opposed to datum. The debate over appropriate usage continues, but "data" as a singular form is far more common.
In English, the word datum is still used in the general sense of "an item given". In cartography, geography, nuclear magnetic resonance and technical drawing it is often used to refer to a single specific reference datum from which distances to all other data are measured. Any measurement or result is a datum, though data point is now far more common.
Aquarium is the debut studio album by Danish-Norwegian band Aqua. The album was released in Scandinavia on 26 March 1997 and in the United States on 9 September 1997. Although the group had been together for three years under their original name Joyspeed, their only release under that name was a single called "Itzy Bitsy Spider". The album is best known for including the successful singles "Barbie Girl", "Doctor Jones" and "Turn Back Time", the first of those being a huge hit across the globe. (The album was preceded by the two singles "Roses Are Red" and "My Oh My", with the latter re-released in 1998.)
The album's third single, "Barbie Girl" brought the group to international attention after reaching number one in both Denmark and Norway, as well as across Europe and in Australia and New Zealand. It would later peak at number 7 in the US. Its success helped the album reach number one in both the group's home countries, and make the top 10 in the UK and US. While not selling as highly "Barbie Girl", the album's fourth single "Doctor Jones" was released in late 1997/early 1998 and became a number one in Denmark, Norway, Australia and the UK. "Turn Back Time" would later give the group their third consecutive number one single in the UK, despite only reaching number 16 in Denmark. The final single, "Good Morning Sunshine" failed to chart highly and was only released in select regions like the earlier "Lollipop (Candyman)", the group's only other song to chart in the US. The album has sold 14 million copies worldwide.
An aquarium is a clear-sided container in which water-dwelling plants and animals are kept.
Aquarium (or the plural Aquaria) may also refer to:
Aquarium or Akvarium (Russian: Аква́риум) is a Russian rock group formed in Leningrad (now Saint Petersburg, Russia) in 1972. The band had many member changes over its 40-year history, and at the end the only remaining original member was lead singer and founder Boris Grebenshikov. Former band members have included Anatoly Gunitsky, Dyusha Romanov, Sergey Kuryokhin, and Vsevolod Gakkel.
Aquarium was formed in 1972 by two friends: Boris Grebenshikov, then a student of Applied Mathematics at Leningrad State University, and Anatoly (George) Gunitsky, a playwright and absurdist poet. The founding members were Grebenshikov, George (drums), Tsatsanidi Alexander (bass), Alexander Vasilyev (keyboards), Valery warmed (sound).
The popular story behind the name "Aquarium" is that it was inspired by the Budapest street Leningrad pub "The Aquarium" and suggested by one of the band members. However, Grebenshikov has given differing stories in interviews, suggesting alternately that it came through band word association sessions or was inspired a glass aquarium-like building.
