The A-Z web glossary, as explained by Wikpedia
| Page Rank |
| PageRank is a link analysis algorithm that assigns a numerical weighting to each element of a hyperlinked set of documents, such as the World Wide Web, with the purpose of "measuring" its relative importance within the set. The algorithm may be applied to any collection of entities with reciprocal quotations and references. The numerical weight that it assigns to any given element E is also called the PageRank of E and denoted by PR(E). Read more at Wikipedia |
| Page View |
| A page view (PV) or page impression is a request to load a single page of an Internet site. On the World Wide Web a page request would result from a web surfer clicking on a link on another HTML page pointing to the page in question. This should be contrasted with a hit, which refers to a request for a file from a web server. There may therefore be many hits per page view. Read more at Wikipedia |
| Payment Gateway |
| A payment gateway is an e-commerce application service provider service that authorizes payments for e-businesses, online retailers, bricks and clicks, or traditional brick and mortar. It is the equivalent of a physical point of sale terminal located in most retail outlets. Payment gateways encrypt sensitive information, such as credit card numbers, to ensure that information passes securely between the customer and the merchant. Read more at Wikipedia |
| PHP |
| PHP is a computer scripting language originally designed for producing dynamic web pages. It is for server-side scripting but can be used from a command line interface or in standalone graphical applications. While PHP was originally created by Rasmus Lerdorf in 1995, the main implementation of PHP is now produced by The PHP Group and serves as the de facto standard for PHP as there is no formal specification.Released under the PHP License, the Free Software Foundation considers it to be free software. PHP is a widely used general-purpose scripting language that is especially suited for web development and can be embedded into HTML. It generally runs on a web server, taking PHP code as its input and creating web pages as output. It can be deployed on most web servers and on almost every operating system and platform free of charge. PHP is installed on more than 20 million websites and 1 million web servers.The most recent major release of PHP was version 5.2.6 on May 1, 2008. Read more at Wikipedia |
| Pixel |
| In digital imaging, a pixel (picture element[1]) is the smallest piece of information in an image. Pixels are normally arranged in a regular 2-dimensional grid, and are often represented using dots, squares, or rectangles. Each pixel is a sample of an original image, where more samples typically provide a more accurate representation of the original. The intensity of each pixel is variable; in color systems, each pixel has typically three or four components such as red, green, and blue, or cyan, magenta, yellow, and black.

| Platform |
| In computing, a platform describes some sort of hardware architecture or software framework (including application frameworks), that allows software to run. Typical platforms include a computer's architecture, operating system, programming languages and related runtime libraries or graphical user interface. Operating system platform examples: Microsoft Windows, Linux, Solaris, Mac OS. Software platform examples: Java - JDK and JRE, .NET Framework - operating system dependence (MS Windows), Mozilla Prism XUL and XUL Runner, Adobe AIR, Mono. Read more at Wikipedia |
| Plug-in |
| A plug-in (plugin, addin, add-in, addon, add-on or snap-in; but see extension) is a computer program that interacts with a host application (a web browser or an email client, for example) to provide a certain, usually very specific, function "on demand". Applications support plugins for many reasons. Some of the main reasons include: enabling third-party developers to create capabilities to extend an application, to support features yet unforeseen, to reduce the size of an application, and to separate source code from an application because of incompatible software licenses. Examples would be the plug-ins used by web browsers to play video and presentation formats , such as: Flash, QuickTime, Real Media, Microsoft Silverlight, 3DMLW) Read more at Wikipedia |
