Household Electrical Supply is the supply of electric current to our houses.
50 Hz is the frequency of Alternating Current. As we know that Alternating Current continuously changes its direction. 50 Hz is the frequency with which it changes the direction.
Household Circuits are in parallel because in series, if one appliance stops to work, others too will stop working. But in parallel, others keep working.
