Nudity or nakedness is the state of wearing no clothing. The wearing of clothing is exclusively a human characteristic. The amount of clothing worn depends on functional considerations (such as a need for warmth or protection from the elements) and social considerations. In some situations the minimum amount of clothing may be socially acceptable, while in others much more clothing is expected.
Modern humans are the only survivors of several species of naked apes who may have worn clothes, according to DNA studies of clothing lice. This study suggests that clothing may have been used as long ago as 650 thousand years ago – much longer than previously thought. Embarrassment and shame may be consequences of the prolonged infancy of human offspring whose care implies a state of monogamy for some long time, together with the reduction of the temptations of infidelity
People, as individuals and in groups, have varying attitudes towards their own nudity. Some people are relaxed about appearing less than fully clothed in front of others, while others are uncomfortable or inhibited in that regard. People are nude in a variety of situations, and whether they are prepared to disrobe in front of others depends on the social context in which the issue arises. For example, people need to bathe without clothing, some people also sleep in the nude, some prefer to sunbathe in the nude or at least topless. Many people are prepared to disrobe for a medical examination, while others are nude in other situations. Some people adopt nudism as a lifestyle.
An airport is a location where aircraft such as fixed-wing aircraft, helicopters, and blimps take off and land. Aircraft may be stored or maintained at an airport. An airport consists of at least one surface such as a runway for a plane to take off and land, a helipad, or water for takeoffs and landings, and often includes buildings such as control towers, hangars and terminal buildings.
Larger airports may have fixed base operator services, seaplane docks and ramps, air traffic control, passenger facilities such as restaurants and lounges, and emergency services. A military airport is known as an airbase or air station.
A water airport is a water aerodrome (an area of open water used regularly by seaplanes or amphibious aircraft for landing and taking off), usually with passenger facilities on adjacent land, which acts as an airport: All pages with titles containing "water airport".
The terms aerodrome, airfield, and airstrip may also be used to refer to airports, and the terms heliport, seaplane base, and STOLport refer to airports dedicated exclusively to helicopters, seaplanes, or short take-off and landing aircraft.
Data ( /ˈdeɪtə/ DAY-tə, /ˈdætə/ DA-tə, or /ˈdɑːtə/ DAH-tə) are values of qualitative or quantitative variables, belonging to a set of items. Data in computing (or data processing) are often represented by a combination of items organized in rows and multiple variables organized in columns. Data are typically the results of measurements and can be visualised using graphs or images. Data as an abstract concept can be viewed as the lowest level of abstraction from which information and then knowledge are derived. Raw data, i.e., unprocessed data, refers to a collection of numbers, characters and is a relative term; data processing commonly occurs by stages, and the "processed data" from one stage may be considered the "raw data" of the next. Field data refers to raw data collected in an uncontrolled in situ environment. Experimental data refers to data generated within the context of a scientific investigation by observation and recording.
The word data is the plural of datum, neuter past participle of the Latin dare, "to give", hence "something given". In discussions of problems in geometry, mathematics, engineering, and so on, the terms givens and data are used interchangeably. Such usage is the origin of data as a concept in computer science or data processing: data are numbers, words, images, etc., accepted as they stand.
