Difference between Present Value (PV) and Discounted Cash flow (DCF)?

Posted at: 2014-12-05 
Ok so im reading a book on this currently but i do not fully understand the meaning of it

What is DCF does it show the future value currently from your present value? it is computed by F = P x (1 x R)^number of years?

F = Future value, P= present value, R = interest rate

Is this correct? what does it show? You need PV to calculate DCF?

PV is computed by using P = F/ (1 x R)^number of years

is this also correct?
