GIF (other)
The Graphics Interchange Format (GIF; or , ) is a Raster graphics, bitmap Image file formats, 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. The format can contain up to 8-bit color, 8 bits per pixel, allowing a single image to reference its own Palette (computing), palette of up to 256 different colors chosen from the 24-bit color, 24-bit RGB color model, RGB color space. It can also represent multiple images in a file, which can be used for animations, and allows a separate palette of up to 256 colors for each frame. These palette limitations make GIF less suitable for reproducing color photographs and other Image gradient, images with color gradients but well-suited for simpler images such as graphics or logos with solid areas of color. GIF images are compressed using the Lempel–Ziv–Welch (LZW) lossless data compression technique to reduce the file siz ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Animated GIF
The Graphics Interchange Format (GIF; or , see pronunciation) is a bitmap In computing, a bitmap is a mapping from some domain (for example, a range of integers) to bits. It is also called a bit array or bitmap index. As a noun, the term "bitmap" is very often used to refer to a particular bitmapping application: t ...

MP4 File Format
MPEG-4 Part 14 or MP4 is a digital multimedia container format most commonly used to store video and audio, but it can also be used to store other data such as subtitles and still images. Like most modern container formats, it allows streaming over the Internet. The only filename extension for MPEG-4 Part 14 files as defined by the specification is .mp4. MPEG-4 Part 14 (formally ISO/IEC 14496-14:2003) is a standard specified as a part of MPEG-4. Portable media players are sometimes advertised as "MP4 players", although some are simply MP3 players that also play AMV video or some other video format, and do not necessarily play the MPEG-4 Part 14 format. History MPEG-4 Part 14 is an instance of the more general ISO/IEC 14496-12:2004 (MPEG-4 Part 12: ISO base media file format) which is directly based upon the QuickTime File Format which was published in 2001. MPEG-4 Part 14 is essentially identical to the QuickTime File Format, but formally specifies support for Initial Object ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Netscape (web Browser)
The Netscape web browser is the general name for a series of web browsers formerly produced by Netscape, Netscape Communications Corporation, which eventually became a subsidiary of AOL. The original browser was once the dominant browser in terms of usage share, but as a result of the Browser wars#First Browser War, first browser war, it lost virtually all of its share to Internet Explorer due to Microsoft's anti-competitive bundelling of Internet Explorer with Windows. Netscape was discontinued and support for all Netscape browsers and client products was terminated on March 1, 2008. Timeline and history Netscape-based (versions 1.0–4.8) releases Netscape Navigator (versions 1.0–4.08) Netscape Navigator was the name of Netscape's web browser from versions 1.0 through 4.8. The first version of the browser was released in 1994, known as Mosaic and then Mosaic Netscape until a legal challenge from the National Center for Supercomputing Applications (makers of NCSA Mosaic, w ...
