What is relationship between discount rate and inter bank rate?

I agree with Mr Tareg answers, thanks for the invitation

...

Mr.Tarek Muneer mentioned it clearly and nothing to add. 

Discount rate is the interest rate on loans set by the federal bank to lend money to other banks and financial institutions.

Inter bank rate is the interest rate on which bank's lend money to other banks.

I apologize for the answer I leave the answer to the specialists experts in this the field that's not my area.
