Data segment

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 (band)

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.

Data (word)

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.

Usage in English

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.

List of Death Note episodes

Death Note is a 37-episode anime series based on the manga series of the same title written by Tsugumi Ohba and illustrated by Takeshi Obata. Death Note aired in Japan on the Nippon Television (NTV) network every Tuesday, from October 3, 2006, to June 26, 2007. The plot of the series primarily revolves around high school student Light Yagami, who decides to rid the world of evil with the help of a supernatural notebook titled Death Note. This book causes the death of anyone whose name is written in it and is passed on to Light by the God of Death (or Shinigami) Ryuk after he becomes bored within the Shinigami world.

A three-hour "Director's Cut" compilation TV special, titled "Death Note: Relight: Visions of a God", aired on NTV a few months after the anime concluded. Although advertised to be the "complete conclusion", the popularity of the series inspired the release of a second TV special, titled "Death Note: Relight 2: L's Successors" nearly a year later. These specials recap the first and second arcs of the anime respectively, with new scenes added to fill in any plot holes resulted from omitted footage.

Pursuit (video game)

Pursuit is a single-player arcade game by Kee Games, originally released in 1975. The player plays a World War I flying ace who tries to shoot down enemy planes. Gameplay relies on a first person perspective representation. Pursuit also marks the first time Atari Inc. publicly acknowledged its relationship with Kee.

Technology

The game is housed in a custom wide cabinet modeled to look like a World War I biplane cockpit. It includes a similarly modeled flight stick with top-mounted fire button. The game's PCB is composed of discrete technology and includes Atari/Kee's Durastress technology. One overlay provides the onscreen crosshair.

Gameplay

The player uses a flight stick to steer the plane up, down, right, and left to get the enemy in his or her sights. The top-mounted fire button is then used to shoot the enemy plane and gain points.
