 Hello everyone, my name is Ashish Panchadhar and I am persuading electronics and communication engineering in Avante Institute of Engineering and Technology at my final semester at Hyderabad and Actually, I was recently placed in an IT services and software company called as value momentum. It's a good MNC So actually I have done a course called demystifying networking From NPTEL. So why I actually done that course because I was Really confused at the beginning how actually the data works How the data travels from the network host to the routers and then routers to my phone So after taking up that course, I was actually Cleared a lot of my doubts that they are physical layers present at that network layers present So how the packets travel and they actually taught me the Cisco packet racer and which actually helped me in a lot of interviews Thank you
