What are Bandwidth and Data Rate of a Network?

Bandwidth and Data Rate are the terms often used to indicate the performance of network e.g. internet speed promised by service provider. This video explains what is data rate and how we calculate bandwidth from the data rate. What is the relation between data rate and bandwidth. While the topic is kept simple and for a broader audience. One may need to look further into understanding autocorrelation function, Power Spectral Density, and Line Coding, all of which are covered in the Communication Systems Playlist available in the following link.
