# Confused between bandwidth and frequency

I am new to Computer Science and started learning about computer networking very recently. I know that bandwidth means how many bits can be sent through the channel in 1 second. However, recently I came across another definition of bandwidth which says it is the range of frequency where the signal is received.

How to think intuitively of this? Frequency is the number of cycles per second. What is the relation between frequency and bandwidth?

Please note that I am a lay man. Kindly elaborate.
