WAP stands for "WIRELESS APPLICATION PROTOCOL". WAP is a standard for mobile communication systems. WAP allows wireless/mobile devices to access and retrieve information from a number of information sources mainly from world wide web.In short we can say that WAP converts mobile phone into a mini web browser.
PARTS OF WAP ENABLED SYSYTEM:
There are three major components of a WAP-enabled communication system:
WAP-gatewayHTTP web server WAP- device (i.e. mobile phone)FUNCTION OF WAP:
WAP allows us:
To read internet based Email. To send internet based Email. Retrieve informationfrom internet. M-commerce (mobile commerce).LIMITATION OF WAP:
Yes, it is the size of the screen of your mobile phone that is the greatest hurdle in the way of WAP.You know very well that your mobile phone is a pocket sized device with very small screen, therefore, it is not possible to view high resolution eye catching images and heavy text at a time.WAP supports only grey scale images in ".wbmp" format.
HOW WAP WORKS?
WAP source files are located on the web server and these files are transported by using HTTP to WAP gateway.Gateway behaves as a compiler for source code and converts it into byte code and finally send it to your mobile phone via WAP.
