In justice and law, house arrest is a measure by which a person is confined by the authorities to their residence. Travel is usually restricted, if allowed at all. House arrest is an alternative to being in a prison while awaiting trial or after sentencing.

A prison, also known as a jail, gaol, penitentiary, detention center, correction center, correctional facility, or remand center, is a facility where people are confined against their will and denied a variety of freedoms under the authority of the state, generally as punishment for various crimes. Authorities most commonly use prisons within a criminal-justice system: people charged with crimes may be imprisoned until their trial; those who have pled or been found guilty of crimes at trial may be sentenced to a specified period of imprisonment.
