Not like that..i am telling you the meaning of Ajax in gist , Ajax is such type of script if you use it in your site , it will load only a little part of your site but not the entire site..if you are using a general contact form in your site and any person contact you through that contact form ..when he will submit it after writing his message then the entire site will load again to store the content in your sql database , but in case of ajax in stead of loading the entire site , it will load some portion of your site like your contact page it will save your bandwidth and database storage too.
Thanks.
