Hellow ,

some basics things about the Ajax. I think Ajax is cool and it’s a

buzzword in today’s computing world.

The abbrivation of Ajax is Asynchronous JavaScript and XML.

Ajax is Used by many popular internet companies for many reasons . In

normal client server environment what happens the client make a http

request to the webserver and the webserver response according to

the requirement.

Now lets see hoe Ajax works:

The client makes a http request for specific information and the server

returns the specific requsted information(not the whole page)

Here are the advantages of Ajax :

In Ajax the small request will be send (only required i.e perticular part)

so the response time will be less each time the whole page is not

required to retrive so network traffic wiil be decreased . In ajax when u

r submit the page the page is not flickering , give the nore responsive

feel to user.

Ajax behave like desktop appication

In ajax only the perticular part of the page needs to updated,so the

response action is faster

Following are the drawbages of Ajax :

One of the most common poblem is to integrated with browser if the

use click on back button might not allowed them to get the information

that they want.

Another disadvantages is that in ajax perticulat part is updated so

sometimes it might create synchronization problem with existing part

otheres disadvantages are

Cross-browser incompatibilities

Accessibility issues

Extra programming

so these are the things …….
