According to Professor Jai Kumar Radhakrishnan at Tata Institute of Fundamental Research, computer science shares a very close relationship with the field of mathematics. It goes almost hand in hand. Some computer science departments devise a curriculum which emphasises the mathematical component, whereas others have engineering as the area of emphasis.

Make sure you are aware where the emphasis lies when you choose to opt for a specific course. Zero in on the course that is suitable to your requirements.

Information Technology is a field that is constantly growing and being upgraded. Though computers are at the core of all,each specialisation is distinct in character. An MSc in Computer Science is quite different from a Master's degree in Computer Applications or an MSc in Operations Research.

We are here dealing with Computer Science -- a discipline that prepares a person for a career in computing and its applications in the real world of computers. No prior knowledge of computing is required to enter this field. Students of natural sciences, engineering and even arts, humanities and social sciences can enrol.

One can also opt for an integrated MSc degree in Computer Science and Technology such as the one offered by the Indian Institute of Science, Bengaluru or Mysore University. A background in Mathematics is considered necessary in many ways when opting for an MS in Computer Science, along with a good academic record. St. Xavier's College, Kolkata offers a 4-semester, 2-year MSc in Computer Science.

This course offers papers that are in tune with the current IT scenario.The Group in Mathematics and theoretical computer science in TIFR is one of the most premier institutions in the country for research in the field of mathematics, computer science and information technology. C-DAC specialises in application oriented super computing.
