@EEngr: you will typically find a Ground control frequency at an airport that is a dedicated frequency to control ground movement. You will also have a tower frequency that governs take off and landing.
After you land, your switch to ground when directed by tower. (In my experience, usually "when clear of the active" which with multiple runway airports means you have to pay attention to what runway(s) are or are not active.)
The point of the different discrete frequencies is to avoid conflicting or confusing instructions for aircraft taking off and landing, versus those moving to and from the runway environment.
