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.
"Bandwidth" has several different meanings. Among others, it can refer to either a frequency range or to data rate in bits/second. You have to use the context to figure out which is meant.
These two notions of bandwidth are not directly related, but a signal with a wider frequency range (i.e., higher signal bandwidth) can usually transmit data at a higher rate (i.e., has higher data bandwidth). However, the relation also depends on how much noise is present.
