An EVAP system is the system in the car that retrieves fuel vapors from the gas tank, as well as the rest of the fuel system. The EVAP system will then recycle these vapors so they can be burned in the engine. The EVAP port is a test port where a vacuum can be attached to check for leaks in the EVAP system.
