What is Ajax?
Ajax is yet another term that has come into light over the past few years. It was in 2005 when this term was popularized by Google as a type of web development. The initials stand for Asynchronous JavaScript and XML. It is however important to understand that Ajax by itself is not a programming language. Rather it is a new and unique means that enables individuals to create extremely user friendly web applications. In a time when the World Wide Web is being flooded with visitors it comes in as a great tool to assist in the making of various applications. As a result of the effectiveness of Ajax the existing standards of programming have undergone a major revolution and have hence become far more efficient than they ever were. To summarize, the biggest advantage that Ajax offers is the ability to display quick responses plus the increased level of interactivity with end users that it has to offer.
Although not a programming language it is still important to know how Ajax functions. It is basically based on JavaScript along with HTTP requests. Ajax offers the ability to make your JavaScript communicate directly with the server. This is done using JavaScript XMLHttpRequest object. This object comes in very handy in today’s times. This is because by using it your JavaScript can easily collect data from any web server without having to reload the page. This aspect of allowing web pages to request minimal information rather than complete pages is made possible with the use of synchronous data transfer also known as HTTP requests. Basically this is a data transfer interaction that takes place between the browser and the web server.
Three years into the release of this technique we find that internet applications have been made much more simplified with the use of Ajax. Furthermore it is made the whole process much faster and much more responsive to the user’s demand than it ever has been before. The good thing is that it gives all its performance independent of web server software. JavaScript, XML, HTML, and CSS are the web standards on which Ajax is normally based. Hence we see the Ajax makes use of the well defined web standards which are supported by all the major browsers. Ajax has contributed a lot to the world of the internet and it can rightly be said that it has revolutionized working on the internet by making it richer and much more user friendly.
Ajax has a number of benefits which are being utilized by the masses all around the world. It has certain specific benefits when it comes to bandwidth usage. Since the payload is reduced to such a small size it does not need to be redrawn on every update like in the case of complete layouts. Hence you can easily load the relative information and data without wasting too much time. Another great benefit of this technology is the line that it draws between data, format style and function. Programmers are given the opportunity to use separate methods and formats in different aspects of information through the web. Hence programmers have the freedom to use different languages and techniques as per their requirement.
