Vinod seeing your interest in IT, I feel you should go for MBA IT.
IT careers are many and varied, especially with an MBA. The multifaceted nature of the IT industry carries over into its management roles, which can range from project management in software design and development to network and systems management.
There are different ways of admission in MBA. Some institutes prefer CAT/XAT/ MAT scores only for admission to MBA course. And to appear for CAT/XAT/MAT etc student needs to have 50% in graduation. But eligibility criteria varies for various Management Institutes or Universities, they can take different %age in graduation along with CAT/ MAT/ XAT scores.
Another way of admission is internal tests or admission criteria of individual Management Institutes or Universities.
You can check the websites of universities like Amity, Lovely, Chitkara, Manipal etc for more details.
Good luck.

There is a difference between IT and ICT and Its simple as a piece of Cake.
In IT the word I relates to Information that is in forms of ZEROs and ONE, binary so every subset of IT that is Infrastructure (network, server), Information System (application, databases), Information Security (access control, firewalls)are all deals with data in the form of Binary. In short its all about binary data.
In ICT , I relates to Information which can be analog or binary and Communication relates to devices which sends and receive signals, Its all about device technologies which communicate with each other such as radios with station, mobile with tower, TV with the help of decoder, even satellites. Its all about transmission services.
