AJAX is not a new language, but just a new way to use existing standards.
With AJAX you can create better, faster, and more user friendly web
applications.
AJAX is based on JavaScript and HTTP requests.
AJAX = Asynchronous JavaScript And XML
AJAX is an acronym for Asynchronous JavaScript And XML.>
AJAX is not a new programming language, but simply a new technique for
creating better, faster, and more interactive web applications.
AJAX uses JavaScript to send and receive data between a web browser and a web
server.
The AJAX technique makes web pages more responsive by exchanging data with
the web server behind the scenes, instead of reloading an entire web page each
time a user makes a change.
AJAX Is A Browser Technology
AJAX is a technology that runs in your browser. It uses asynchronous data
transfer (HTTP requests) between the browser and the web server, allowing web
pages to request small bits of information from the server instead of whole
pages.
The technology makes Internet applications smaller, faster and more user
friendly.
 AJAX is a web
browser technology independent of web server software.
AJAX Is Based On Open Standards
AJAX is based on the following open standards:
The open standards used in AJAX are well defined, and supported by all major
browsers. AJAX applications are browser and platform independent.
(Cross-Platform, Cross-Browser technology)
AJAX Is About Better Internet Applications
Web applications have many benefits over desktop applications, they can reach
a larger audience, they are easier to install and support, and easier to
develop.
However, Internet applications are not always as "rich" and user-friendly as
traditional desktop applications.
With AJAX, Internet applications can be made richer (smaller, faster, and
easier to use).
You Can Start Using AJAX Today
There is nothing new to learn.
AJAX is based on open standards. These standards have been used by most
developers for several years.
Most existing web applications can be rewritten to use AJAX technology
instead of traditional HTML forms.
AJAX Uses XML And HTTP Requests
A traditional web application will submit input (using an HTML form) to a web
server. After the web server has processed the data, it will return a completely
new web page to the user.
Because the server returns a new web page each time the user submits input,
traditional web applications often run slowly and tend to be less user friendly.
With AJAX, web applications can send and retrieve data without reloading the
whole web page. This is done by sending HTTP requests to the server (behind the
scenes), and by modifying only parts of the web page using JavaScript when the
server returns data.
XML is commonly used as the format for receiving server data, although any
format, including plain text, can be used.
You will learn more about how this is done in the next chapters of this
tutorial.
