 Hello everyone, I am Unmesha Banerjee, an 8 semester student pursuing computer science and engineering from Tejpo Central University Assam. I have been placed in a multinational company called ABB. I have taken up three NPTEL courses so far. They are Ethical Hacking, Cloud Computing and Introduction to Internet of Things. Cybersecurity has always been my passion and Ethical Hacking, I had always wanted to learn Ethical Hacking. The course Ethical Hacking that I had taken up from NPTEL is especially designed for beginners and everything was explained and demonstrated from the fundamental. So, I got a good grasp of everything related to it. The second course that I took up was Cloud Computing. My current BTEC final year project deals with Cloud Computing and blockchain and I have been greatly helped through the course Cloud Computing from NPTEL. The third course that I had taken up is Introduction to Internet of Things which I had taken up this semester and Introduction to Internet of Things is the current state of the art and it deals with fundamentals as well as a few emphasis on the more detailed sections. It is also a highly helpful course for me. Thank you.
