JPEG: (Joint Photographic Experts Group) is a compression method standardized by ISO. JPEG JFIF, which is what people generally mean when they refer to "JPEG", is a file format created by the Independent JPEG Group (IJG) for the transport of single JPEG-compressed images.
TIFF: The Tagged Image File Format (TIFF) was designed from the ground up to alleviate the problems associated with fixed file formats. The key word here is designed . TIFF did not evolve from a de-facto standard. It was created to become the industry standard for image-file exchange. TIFF was a super-set of all existing graphics or image file formats. TIFF incorporates enough flexibility to eliminate the need or justification for proprietary image file formats. As a matter of fact, it is possible to store proprietary information in a TIFF file without violating the intent of the format. TIFF was designed with an eye toward the future, not just for use in the present. The designers of the TIFF file format had three important goals in mind:
Bit map: A representation, consisting of rows and columns of dots , of a graphics image in computer memory . The value of each dot (whether it is filled in or not) is stored in one or more bits of data . For simple monochrome images, one bit is sufficient to represent each dot, but for colors and shades of gray, each dot requires more than one bit of data . The more bits used to represent a dot, the more colors and shades of gray that can be represented.
PNG: Short for P ortable N etwork G raphics, and pronounced ping, a new bit-mapped graphics format similar to GIF . In fact, PNG was approved as a standard by the World Wide Web consortium to replace GIF because GIF uses a patented data compression algorithm called LZW . In contrast, PNG is completely patent-and-license-free. The most recent versions of Netscape Navigator and Microsoft Internet Explorer now support PNG.
SVCD: stands for "Super Video CD". A SVCD is very similar to a VCD; it has the capacity to hold about 35-60 minutes on 74/80 min CDs of very good quality full-motion video along with up to 2 stereo audio tracks and also 4 selectable subtitles. A SVCD can be played on many standalone DVD Players and of course on all computers with a DVD-ROM or CD-ROM drive with the help of software based decoder / player. It is also possible to use menus and chapters, similar to DVDs, on a SVCD and also simple photo album/slide shows with background audio. The quality of a SVCD is much better than a VCD, especially much more sharpen picture than a VCD because of the higher resolution. But the quality depends how many minutes you choose to store on a CD, less minutes/CD generally means higher quality.
ISO: International Standards Organization, responsible for the ISO 9000 and other international quality standards.
DPI: Abbreviation of d ots p er i nch, which indicates the resolution of images. The more dots per inch, the higher the resolution is. A common resolution for laser printers is 600 dots per inch. This means 600 dots across and 600 dots down, so there are 360,000 dots per square inch.
