What is JSP?

Stands for "Java Server Page." This standard was developed by Sun Microsystems as an alternative to Microsoft's active server page (ASP) technology. JSP pages are similar to ASP pages in that they are compiled on the server, rather than in a user's Web browser. After all, they don't call them "server pages" for nothing. However, JSP is Java-based, whereas ASP is Visual Basic-based. JSP pages are useful for building dynamic Web sites and accessing database information on a Web server. Though ... Read more

What is ASP?

ASP has two different meanings in the IT world: 1) Application Service Provider, and 2) Active Server Page. 1) Application Service Provider An Application Service Provider is a company or organization that provides software applications to customers over the Internet. These Internet-based applications are also known as "software as a service" (SaaS) and are often made available on a subscription basis. This means ASP clients often pay a monthly fee to use the software, rather than purchasing a traditional software license. Some SaaS applications can be accessed via ... Read more

What is PHP?

Stands for "Hypertext Preprocessor." (It is a recursive acronym, if you can understand what that means.) PHP is an HTML-embedded Web scripting language. This means PHP code can be inserted into the HTML of a Web page. When a PHP page is accessed, the PHP code is read or "parsed" by the server the page resides on. The output from the PHP functions on the page are typically returned as HTML code, which can be read by the browser. Because the PHP code ... Read more

What Is a Browser Cache?

So you've just finished redesigning your website. You're excited, it looks great, and you're patting yourself on the back. Before you start parading around this new great design like a kid showing off their new toy, you want to give it a whirl and see how it all looks from a visitor’s perspective.

XML Sitemap: How to Do It Right For SEO

Having an XML sitemap on your website has been a widely accepted practice, but not a lot of attention is given to it. The case usually is, when you have a new website, you just generate a sitemap, upload it for search engine spiders to be able to crawl it, and that’s it! Even though, in reality, that’s really it, your XML sitemap deserves a bit more attention than that. Let’s start with the basics.  New to Search Engine Optimization? What is an ... Read more

What is jQuery?

jQuery is a JavaScript library that allows web developers to add extra functionality to their websites. It is open source and provided for free under the MIT license. In recent years, jQuery has become the most popular JavaScript library used in web development. To implement jQuery, a web developer simply needs to reference the jQuery JavaScript file within the HTML of a webpage. Some websites host their own local copy of jQuery, while others simply reference the library hosted by Google or the jQuery server. For example, a webpage may load the ... Read more

What is XML?

Stands for "Extensible Markup Language." (Yes, technically it should be EML). XML is used to define documents with a standard format that can be read by any XML-compatible application. The language can be used with HTML pages, but XML itself is not a markup language. Instead, it is a "metalanguage" that can be used to create markup languages for specific applications. For example, it can describe items that may be accessed when a Web page loads. Basically, XML allows you to ... Read more

What is XHTML?

Stands for "Extensible Hypertext Markup Language." XHTML is markup language used to create webpages. It is similar to HTML but uses a more strict XML-based syntax. The first version of XHTML (1.0) was standardized in 2000. For several years, XHTML was the most common language used to create websites. It has since been superseded by HTML5. Why XHTML? As HTML evolved over the first few decades of the web, browsers became increasingly lenient in how they parsed webpage source code. The result was that websites were rendered inconsistently between browsers. One of the main ... Read more

What is CSS?

Stands for "Cascading Style Sheet." Cascading style sheets are used to format the layout of Web pages. They can be used to define text styles, table sizes, and other aspects of Web pages that previously could only be defined in a page's HTML. CSS helps Web developers create a uniform look across several pages of a Web site. Instead of defining the style of each table and each block of text within a page's HTML, commonly used styles need to be defined only once ... Read more

What is W3C?

Stands for "World Wide Web Consortium." The W3C is an international community that includes a full-time staff, industry experts, and several member organizations. These groups work together to develop standards for the World Wide Web. The mission of the W3C is to lead the Web to its full potential by developing relevant protocols and guidelines. This is achieved primarily by creating and publishing Web standards. By adopting the Web standards created by the W3C, hardware manufacturers and software developers can ensure their equipment and programs work with the latest ... Read more
