Wall switch to half hot outlet both standard
A normal switch with power located at the switch could have two cables coming in with the neutral/white wires are all connected together. Then, the ground wires are all connected with a pigtail to the green screw on the switch. Lastly, one hot/black connects to one switch terminal and the other hot/black to the other switch terminal.

When you turn the switch on power is passed through to the fixture or receptacle. This is quite common.
