The Graphics Interchange Format ( GIF; / ɡɪf / GHIF or / dʒɪf / JIF, see § Pronunciation) is a bitmap image format that was developed by a team at the online services provider CompuServe led by American computer scientist Steve Wilhite and released on June 15, 1987.
Steve Wilhite's slide at the 2013 Webby Awards. The pronunciation of GIF, an acronym for the Graphics Interchange Format, has been disputed since the 1990s.Popularly rendered in English as a one-syllable word, the acronym is most commonly pronounced / ɡ ɪ f / ⓘ (with a hard g as in gift) or / dʒ ɪ f / ⓘ (with a soft g as in gem), differing in the phoneme represented by the letter G.
Image file format. An image file format is a file format for a digital image. There are many formats that can be used, such as JPEG, PNG, and GIF. Most formats up until 2022 were for storing 2D images, not 3D ones. The data stored in an image file format may be compressed or uncompressed. If the data is compressed, it may be done so using lossy ...

The motivation for creating the PNG format was the realization, on 28 December 1994, that the Lempel–Ziv–Welch (LZW) data compression algorithm used in the Graphics Interchange Format (GIF) format was patented by Unisys. The patent required that all software supporting GIF pay royalties, leading to a flurry of criticism from Usenet users.
Compared to B-DNA, the A-DNA form is a wider right-handed spiral, with a shallow, wide minor groove and a narrower, deeper major groove. The A form occurs under non-physiological conditions in partly dehydrated samples of DNA, while in the cell it may be produced in hybrid pairings of DNA and RNA strands, and in enzyme-DNA complexes.
In liquid form, H2O is also called "Water" at standard temperature and pressure . Because Earth's environment is relatively close to water's triple point, water exists on Earth as a solid, a liquid, and a gas. [21] It forms precipitation in the form of rain and aerosols in the form of fog.
Lidar ( / ˈlaɪdɑːr /, also LIDAR, LiDAR or LADAR, an acronym of "light detection and ranging" [1] or "laser imaging, detection, and ranging" [2]) is a method for determining ranges by targeting an object or a surface with a laser and measuring the time for the reflected light to return to the receiver.
