Hi,
If you have basic knowledge of computers, then after completing your class 12th, you can go for CCNA training for computer networking and after completion of training, you can sit for CCNA global certification exam.
If you succeed, then you will be Cisco certified network associate, a globally valued networking professional certified in associate level. With the help of networking knowledge and CCNA certificate, you can penetrate in IT domain as network engineer.

Hi,
At this moment, it is good. With lot of new technologies coming in like cloud and Big data (not wholly new, but relatively new at least in the Indian space), there is some growth that is deemed to be possible until at least the next 5-10 years. This duration should be good enough to establish oneself firm footed.
Also, another mandate is the operation of Indian IT industry of late in the mode of "survival of the fittest". So, one should constantly be on their toes to keep up with the dynamic nature of this work space.

It would be good for you to go for animation and graphics related courses. There are lots of job opportunities in this field.

Hi Raseen,
Your low marks might trouble you, if you opt for engineering, but there are other courses around for you to choose. You can opt for B.Sc (IT or CS) or go for the BCA + MCA course. All these courses require PCM combination. So, you can opt for it. I don't think low marks in mathematics will cause any problem in these courses.
I hope it helps. If you have any further questions, kindly revert.
