In computer science, random access (sometimes called direct access) is the ability to access an element at an arbitrary position in a sequence in equal time, independent of sequence size. The position is arbitrary in the sense that it is unpredictable, thus the use of the term "random" in "random access". The opposite is sequential access, where a remote element takes longer time to access. A typical illustration of this distinction is to compare an ancient scroll (sequential; all material prior to the data needed must be unrolled) and the book (random: can be immediately flipped open to any random page). A more modern example is a cassette tape (sequential—you have to fast-forward through earlier songs to get to later ones) and a CD (random access—you can skip to the track you want).

In data structures, random access implies the ability to access any entry in a list in constant (i.e. independent of its position in the list and of list's size, i.e. Failed to parse (Missing texvc executable; please see math/README to configure.): O(1) ) time. Very few data structures can guarantee this, other than arrays (and related structures like dynamic arrays). Random access is critical to many algorithms such as binary search, integer sorting or sieve of Eratosthenes. Other data structures, such as linked lists, sacrifice random access to make for efficient inserts, deletes, or reordering of data. Self-balancing binary search trees may provide an acceptable compromise, where access time is equal for any member of a collection and only grows logarithmically with its size.

Julian Fernando Casablancas (born August 23, 1978) is an American musician, singer-songwriter and frontman of The Strokes. Casablancas pursued a solo career during The Strokes' hiatus, releasing the album Phrazes for the Young on November 3, 2009.

Julian Casablancas was born in New York City, to Spanish American business mogul John Casablancas, the founder of Elite Model Management, and Jeanette Christiansen, a former model and onetime Miss Denmark. His paternal grandfather, Fernando Casablancas, was a well-known textile businessman. His parents divorced and his mother subsequently married painter Sam Adoquei. Adoquei helped shape Casablancas' early musical taste by exposing him to music such as The Doors, which was markedly different from the mostly Phil Collins-influenced music he listened to as a child. In 2005, Julian married the assistant to the Strokes' manager, Juliet Joslin. In 2010, they welcomed a son, Cal Casablancas.

The first member of The Strokes Casablancas met was Nikolai Fraiture, who attended Lycée Français de New York with him (Fraiture graduated in 1997, Casablancas in 1996). When he was 14, Casablancas' father sent him to Institut Le Rosey, an elite boarding school in Switzerland. There, he met future Strokes member Albert Hammond, Jr. Casablancas attended The Dwight School with two other future Strokes, Nick Valensi and Fabrizio Moretti. Casablancas never finished school, but continued to take music classes, where he says he first enjoyed himself in class.

Hansjörg "Giorgio" Moroder, named on record sleeves often only Giorgio (born 26 April 1940, Urtijëi, South Tyrol, Italy) is an Italian (of Ladin ethnicity) record producer, songwriter and performer based in Los Angeles.

In addition to producing several hits with Donna Summer, Moroder also produced a number of electronic disco hits for The Three Degrees, two albums for Sparks, a handful of songs on Bonnie Tyler's album Bitterblue as well as her 1985 single "Here She Comes" and a score of songs for performers including David Bowie, Irene Cara, Madleen Kane, Melissa Manchester, Blondie, Japan, and France Joli.
