What is the difference between combined cycle and cogeneration?

In Cogeneration Plant :

The generated steam in boiler is used for both power generation & process heating, thereby reducing the condenstion losses compared to thermal power plant.

In combined cycle first is gas turbine , rather than wasting the flue gas from gas turbine, we are sending it into boiler and again generating steam for running steam turbine.

Both the ways we are increasing the thermal efficiency of the plant
