ISO Definition Stands for “International Organization for Standardization.” Yes, technically the acronym should be “IOFS,” but I guess ISO sounds better. The ISO works with standards institutes from over 150 countries to develop technology and product standards. These standards lead to a more efficient, safer, and cleaner development of products. It also leads to more ..
Media Compression Definition Like file compression, the goal of media compression is to reduce file size and save disk space. However, media compression algorithms are specific to certain types of media, such as image, audio, and video files. Most popular image formats use some type of compression. Three of the most common include JPEG, GIF, and PNG. JPEG compression, which is commonly used for ..
MPEG Definition Stands for “Moving Picture Experts Group.” MPEG is an organization that develops standards for encoding digital audio and video. It works with the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) to ensure media compression standards are widely adopted and universally available. The MPEG organization has produced a number of digital media standards since its inception ..
Animated GIF Definition An animated GIF is a GIF file that includes multiple images or “frames.” These frames are played back in sequence when the file is opened or displayed in a web browser. The result is an animated clip or a short movie. The GIF file format includes a Graphics Control Extension (or “GCE block”), which enables a single ..

The PNG format was introduced in 1994, after the GIF and JPEG formats had already been around for several years. Therefore, PNG includes many of the benefits of both formats. For ..
Raster Graphic Definition Most images you see on your computer screen are raster graphics. Pictures found on the Web and photos you import from your digital camera are raster graphics. They are made up of grid of pixels, commonly referred to as a bitmap. The larger the image, the more disk space the image file ..
Typeface Definition A typeface is a set of characters of the same design. These characters include letters, numbers, punctuation marks, and symbols. Some popular typefaces include Arial, Helvetica, Times, and Verdana. While most computers come with a few dozen typefaces installed, there are thousands of typefaces available. Because they are vector-based (not bitmaps), typefaces can ..
Vector Graphic Definition Unlike JPEGs, GIFs, and BMP images, vector graphics are not made up of a grid of pixels. Instead, vector graphics are comprised of paths, which are defined by a start and end point, along with other points, curves, and angles along the way. A path can be a line, a square, a ..
