As there is an increasing trend of the combination products companies manufacturing such products should be able to tackle the problems involved in the de

This year alone 12.8 million new websites have been added to the internet. With those numbers it is easy to see why so many sites disappear into the black hole of obscurity.

With the establishment of Rajiv Ghandi Chandigarh Technology Park (RGCTP), Chandigarh has not only come up on the national map but also on the international one. Within a single year Infosys, Virsa, Net-Solutions, Taurusagile, and IBM are a few international IT companies which have established their units here.
