Hardware & Networking

Computer Science is the best option in this line of your choice with specialized courses in internet security and more.

If you are from a science background and want your career in computer Science, please do B.Tech CS instead of B.Sc. Hons CS!
There is no value of B.Sc. Hons CS eventually you will have to do M.Sc. Or MCA. Companies prefer B.Tech students over B.Sc/BCA/MCA/M.Sc students. Even if you get a job, the package will be low. After B.Sc. You will not be eligible for GATE. Now, if you are from a commerce background then do BCA instead of B.Sc. CS as it will give you more practical knowledge!
All the best!

Yes, you can apply, it depends on the college but most of the NITs offer the security courses, not a specialised degree.

Hi Aditi,
Yes, you can do Diploma in cyber security after matriculation. You should go for it. This is one of the most demanding subject as per new society. There are huge job opportunities. Best of luck.
