Can anyone describe the difference between relative risk, absolute risk and attributable risk?

Relative Risk(RR)- comparative probabilty asking.. how much more likely?
= incidence rate of exposed grp DIVIDED byt he
incidence rate of unexposed grp.
Attributable Risk(AR)- comparative probability asking....how many more
cases in one grp?
=IR of exposed grp MINUS the IR of unexposed grp.
Both are observational used for cohort studies...
Not sure about absolute risk?
