MCA

Hello Mayank,
Since you have done your Bachelors degree in IT sector, MBA (IT) would be the better choice as there are plenty of job opportunities available in this field.
All the best!

You are eligible to pursue MCA by distance learning. Please refer to following link for details of MCA at IGNOU: http://www.ignou.ac.in/ignou/aboutignou/school/socis/programmes/detail/174/2

Both are professional courses and have equal significance. You can get a good placement after both the courses. You can opt for any course as per your interest and knowledge.

Graduation is the basic qualification required. Degree holders must have studied mathematics as a subject either in class 12th or graduation. Admission to the course is done through entrance test like AIMCET and NIMCET. The course has equal weightage as that of B.Tech in CSE/IT. After completion of the course, you can try for jobs in Infosys, Wipro, Railways, PSU or Government departments.

The MCA degree is only available in India. Similar programs using different notations are available. You need to check the programs to know if you would be interested to pursue the same such as MS IT or MS CS. Can you mention your marks?

MCA duration is 3year. but in the corresponding MCA its depend on institutions. some institute provide 2year for corresponding MCA. the fees also depend on institutions. the minimum MCA course fee 2.5-3.0lk, 35-45k per sem.

Both the courses are good. But, MCA is best because MCA is an IT dependent fully professional 3 year course. MCA is top demandable course in the MNCs (IT sector). But, if you are interested to do B.Ed or if you want to be a teacher or do Ph.D then M.Sc CS is good for you.

Linux device driver courses are part of System Programming PG Diploma courses. Very rarely this course is offered as a separate course. You can learn Linux Device driver fundamentals and programming yourselves as you must be having good C and C++ exposure during MCA.
