Data

Data (/ˈdeɪtə/ DAY-tə, /ˈdætə/ DA-tə, or /ˈdɑːtə/ DAH-tə) is a set of values of qualitative or quantitative variables; restated, pieces of data are individual pieces of information. Data is measured, collected and reported, and analyzed, whereupon it can be visualized using graphs or images. Data as a general concept refers to the fact that some existing information or knowledge is represented or coded in some form suitable for better usage or processing.

Raw data, i.e. unprocessed data, is a collection of numbers, characters; data processing commonly occurs by stages, and the "processed data" from one stage may be considered the "raw data" of the next. Field data is raw data that is collected in an uncontrolled in situ environment. Experimental data is data that is generated within the context of a scientific investigation by observation and recording.

The Latin word "data" is the plural of "datum", and still may be used as a plural noun in this sense. Nowadays, though, "data" is most commonly used in the singular, as a mass noun (like "information", "sand" or "rain").

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.

Lungs (album)

Lungs is the debut studio album by English indie rock band Florence and the Machine, released on 3 July 2009 by Island Records. The album debuted at number two on the UK Albums Chart for five weeks after its release. In January 2010, the album reached a new peak position of number one for two consecutive weeks. Lungs was eventually certified five-times platinum by the British Phonographic Industry. The album also peaked at number two for six weeks on the Irish Albums Chart.

Upon release, Lungs received generally positive reviews from music critics, who praised lead singer Florence Welch's vocals and the album's instrumentation. The album was shortlisted for the 2009 Mercury Prize, and won the MasterCard British Album award at the 2010 Brit Awards. Lungs has sold more than three million copies worldwide.

Production

Florence and the Machine recorded Lungs in the United Kingdom with five different producers—Paul Epworth, James Ford, Stephen Mackey, Eg White, and Charlie Hugall. Most of the songs on the album were mixed by Cenzo Townshend.
