A digital system is one that uses discrete values (often electrical voltages), especially those representable as binary numbers, or non-numeric symbols such as letters or icons, for input, processing, transmission, storage, or display, rather than a continuous spectrum of values (ie, as in an analog system). The distinction of "digital" versus "analog" can refer to method of input, data storage and transfer, or the internal working of a device. The word comes from the same source as the word digit and digitus: the Latin word for finger (counting on the fingers) as these are used for discrete counting. The word digital is most commonly used in computing and electronics, especially where real-world information is converted to binary numeric form as in digital audio and digital photography. Such data-carrying signals carry one of two electronic or optical pulses, logic 1 (pulse present) or 0 (pulse absent). The term is often meant by the prefix "e-", as in e-mail and ebook, even though not all electronic systems are digital. - 1 Digital noise

| When data are transmitted, or indeed handled at all, a certain amount of noise enters into the signal. This can have several causes: data transmitted by radio may be received inaccurately, suffer interference from other radio sources, or pick up background radio noise from the rest of the universe. Microphones pick up everything — signal as well as background noise — without discriminating between signal and noise, so when audio is encoded digitally, it already includes noise. Electric pulses being sent via wires are attenuated by the resistance of the wire, and changed by its capacitance or inductance. Temperature variations can increase or reduce these effects. While digital transmissions are also degraded, slight variations do not matter since they are ignored when the signal is received. With a..."

- This is the article about the photographing device. For other uses, see camera (disambiguation).
A camera is a device used to capture images, as still photographs or as sequences of moving images (movies or videos). The name is derived from camera obscura, Latin for "dark chamber", an early mechanism for projecting images, in which an entire room functioned much as a real-time imaging system. Cameras may work with the visual spectrum or other portions of the electromagnetic spectrum. A camera consists of some kind of enclosed hollow, with an opening or aperture at one end for light to enter, and a recording or viewing surface for capturing the light at the other end. Most cameras have a lens positioned in front of the camera's opening to gather the incoming light and to focus the image, or part of the image, on the recording surface. The diameter of the aperture is often controlled by a diaphragm mechanism, but some cameras have a fixed-size aperture. The size of the aperture and the brightness of the scene control the amount of light that enters the camera during a period of time, and the shutter controls the length of time that the light hits the recording surface. For example, in lower light situations, the shutter speed should be slower (longer time spent open) to allow the film to capture what little light is present. Due to the optical properties of camera lenses, only objects within a certain range of distances from the camera will be reproduced clearly. The process of adjusting this range is known as changing the camera's focus. There are various ways of focusing a camera accurately. The simplest cameras have fixed focus and use a small aperture and wide-angle lens to ensure that everything within a certain range of distance from the lens (usually around 3 metres (10 feet) to infinity) is in reasonable focus. This is usually the kind found on one-use cameras and other cheap cameras. The camera can also have a limited focusing range or scale-focus that is indicated on the camera body. The user will guess or calculate the distance to the subject and adjust the focus accordingly..."

| In computer programming, when one compares the two values x and y, a negative number often indicates x < y, zero x = y and a positive number x > y. Even when two values are not integers, e.g. literal strings, this convention is largely adopted. For example, strcmp returns -1, 0, or 1 according to the lexicographical order, and qsort expects the comparison function to return values according to this convention. This is because it is efficient to do the subtraction x - y resulting in the directional signs above. In sorting algorithms, the efficiency of comparison code is critical since it is one of the major factors of sorting performance. Sometimes, particularly in object-oriented programming, the comparison raises questions of datatypes and inheritance, equality and identity. It is often necessary to distinguish between: - two objects with different datatypes both related to another datatype, e.g. an orange and a lemon, both being citrus fruit
- two different objects of the same type, e.g. two hands
- two objects being equal but distinct, e.g. two $10 banknotes
- two different references to the same object, e.g. two nicknames for the same person
Sameness and difference can be relative or graduated as well as absolute, particularly in fuzzy logic, artificial intelligence, signal processing, lossy data compression and pattern recognition. See also: Regular expression - See also: Comparison of adjectives.
Comparison, in grammar, is a property of adjectives and adverbs in most languages; it describes systems that distinguish the degree to which the modifier modifies its complement. English, ..."
