Computer Science

It depends on your career objective.
The first step towards deciding what MBA stream to pursue is to take into account your past career experiences and make a well thought-out decision about your future career goals. The mixture of your past work experiences with future graduate degree will lead you toward achieving your objective. Without a career objective you cant determine which pathway is optimal to achieve your goals.
If your ultimate career objective is to manage a group of people who do technical work, you may consider an MBA with Engineering Management specialization. Otherwise, you may want to pursue an MBA in general management or project management. The key question to answer when evaluating your career goals is how much you wish to get involved with business-oriented functions of your company. If there is no reason for you to study accounting, finance or strategic management skills, then a technically oriented masters degree might be suitable. On the other hand, if you expect to work in a managerial position for your company and need skills in areas like strategy, finance, marketing, etc. then an MBA in these particular specializations will meet your needs.
To sum up, if you see your career moving away from the technical work and towards managing teams or departments into other functional areas, then MBA with required specializations is appropriate.

This is because the MCA graduates are well aware of the software applications. But for developing new software, M.Sc graduates are preferred. MCAs are most suitable for the working purposes in various companies. While considering a bright career, MCA course will be better than M.Sc in computer science.
