Even though the two post-graduation courses are at same level there are some differences between them. MCA is a 3 year program where as M.Sc. computer science is a 2-year program. MCA covers the software and its application related field. M.Sc computer science covers the both hardware and software field. A person with strong background in computational and scientific field is only able to opt for this course. Those who have pursued a graduation in computer science or computer technology alone can opt for M.Sc computer science, while MCA can be done by any science graduate.
The career opportunities for both these graduates are many. But most MNCs prefer MCA graduates to M.Sc. graduates. 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. computer science.
