How the internet works!

Checking out file types

The one of the important this about my current project (web design)
Is the file types, knowing what all programs

(pronounced jay-peg) is a commonly used method of compressing photographic images. The compression algorithm is "lossy" in that information is removed from the image to assist with decreasing the file size. The greater the compression, the more information is discarded. Files that have undergone jpeg compression usually have extensions such as .jfif, .jpeg, or jpg.

Definition: One of the most commonly used and versatile graphics formats in desktop publishing, TIFF or Tagged Image File Format is a bitmap graphics format that is ideal for high resolution printing to PostScript printers and imagesetters. Originally created as a scanning format, TIFF offers great flexibility for use in page layout applications in part due to multiple color modes, multiple compression types, and cross-platform compatibility. TIFF images support both embedded paths and alpha channels which can be used to create transparent backgrounds for images in a page layout application. Bitmap graphics software such as Adobe Photoshop and Corel Photo-Paint can create and edit TIFF images.

short for Graphics Interchange Format is a file format for storing graphical images up to 256 colors. It uses LZW compression which is a lossless compression method. Until the year 2004, this was covered by a patent owned by Unisys and the reason why the PNG file graphic format was invented. There are two versions of GIF both created by Compuserve. The earlier GIF 87a and the enhanced 89a which stored multiple images (thus allowing animation), and interlacing. GIF files are probably the most popular on the web being used in logos and any color images with 256 or fewer colors. For images containing text GIF tends to be better than JPG because the files tend to be smaller and JPG files usually have some degree of compression and this can make text blurry.

Portable Document Format or PDF is a file format created by Adobe Systems, Inc. PDF uses the PostScript printer description language and is highly portable across computer platforms. PDF documents have a .pdf file extension (myfile.pdf) PSD
The .psd format is the Adobe Photoshop data format which can be read on any machine that has Adobe Photoshop installed. It is cross platform and can be used on both PCs and Macs. The PSD format provides extended support for layering, alpha channels, paths, and vectors. The PSD source file included with our templates are usually in a sliced format which allows you to customize and make changes to the images on your skin. This makes it very useful for customizing your website as you see fit. If any additional fonts are required, they are included with the Photoshop file.

Adobe Flash (formerly Macromedia Flash) is a multimedia platform originally acquired by Macromedia and currently developed and distributed by Adobe Systems. Since its introduction in 1996, Flash has become a popular method for adding animation and interactivity to web pages. Flash is commonly used to create animation, advertisements, and various web page Flash components, to integrate video into web pages, and more recently, to develop rich Internet applications.

HTML, which stands for Hyper Text Markup Language, is the predominant markup language for web pages. It provides a means to create structured documents by denoting structural semantics for text such as headings, paragraphs, lists etc as well as for links, quotes, and other items. It allows images and objects to be embedded and can be used to create interactive forms. It is written in the form of HTML elements consisting of "tags" surrounded by angle brackets within the web page content. It can include or can load scripts in languages such as JavaScript which affect the behavior of HTML processors like Web browsers; and Cascading Style Sheets (CSS) to define the appearance and layout of text and other material. The W3C, maintainer of both HTML and CSS standards, encourages the use of CSS over explicit presentational markup.

Cascading Style Sheets

(CSS) is a style sheet language used to describe the presentation semantics (that is, the look and formatting) of a document written in a markup language. Its most common application is to style web pages written in HTML and XHTML, but the language can be applied to any kind of XML document, including SVG and XUL.

CSS is designed primarily to enable the separation of document content (written in HTML or a similar markup language) from document presentation, including elements such as the layout, colors, and fonts. This separation can improve content accessibility, provide more flexibility and control in the specification of presentation characteristics, enable multiple pages to share formatting, and reduce complexity and repetition in the structural content (such as by allowing for tableless web design). CSS can also allow the same markup page to be presented in different styles for different rendering methods, such as on-screen, in print, by voice (when read out by a speech-based browser or screen reader) and on Braille-based, tactile devices. While the author of a document typically links that document to a CSS style sheet, readers can use a different style sheet, perhaps one on their own computer, to override the one the author has specified.

CSS specifies a priority scheme to determine which style rules apply if more than one rule matches against a particular element. In this so-called cascade, priorities or weights are calculated and assigned to rules, so that the results are predictable.
