Science

Hello Priyanka, The Bachelor of Computer Science or Bachelor of Science in Computer Science (abbreviated BCompSc or BCS or BS CS or B.Sc. CS is a type of Bachelor's degree, usually awarded after three or four years of collegiate study in computer Science, but possibly awarded in fewer years depending on factors such as an institution's course requirements and academic calendar. In some cases it can be awarded in five years. In general, computer Science degree programs emphasize the mathematical and theoretical foundations of computing. Because computer Science is a wide field, courses required to earn a Bachelor of computer Science degree vary. A typical list of course requirements includes topics such as: [2]
Computer programming paradigms
Algorithms
Data structures
Logic&Computation
Computer architecture
Some schools may place more emphasis onmathematicsand require additional courses such as: [3]
Linear algebra
Calculus
Probability theoryandstatistics
Combinatoricsanddiscrete mathematics
Differential calculusandmathematics
Beyond the basic set of computer Science courses, students can typically choose additional courses from a variety of different fields, such as: [4]
Theory of computation
Operating systems
Numerical computation
Compilers, compiler design
Real-time computing
Distributed systems
Computer networking
Data communication
Computer graphics
Artificial intelligence
Human-computer interaction
Information theory
Software testing
Information assurance
Some schools allow students to specialize in a certain area of computer Science. Good luck. Thank you.

Hello Shubhra,
If you have done M.Sc in zoology and wants to become a researcher or lecturer, then you should go for CSIR NET Earth Sciences or CSIR NET Life Sciences. The Council of Scientific and Industrial Research (CSIR) conducts the NET exam on the bi-yearly basis for those who want to make their career in Research and Lectureship field. It is a national level exam. You can get the complete details related to the csir net exam from - https://www.eduncle.com/csir-net-exam must check out.
Candidates having or pursuing their Masters degree in Science Stream are only eligible to take this exam. They should have minimum 55% aggregate marks in Masters, if they are from General/ OBC Category or if they belong to SC/ST/PwD categories, they should have scored minimum 50% aggregate. To apply for the CSIR NET exam candidates maximum age should be 28 years. SC/ST/OBC/PWD/female applicants have upto 5 years relaxation in age criteria
