Boarding school is a school where some or all people study and live during the school year with their fellow students and possibly teachers and/or administrators. The word 'boarding' is used in the sense of "bed and board," i.e., lodging and meals. Some boarding schools also have day students who attend the institution by day and return off-campus to their families in the evenings.
A hostel is a budget-oriented, shared-room ("dormitory") accommodation that accepts individual travelers (typically backpackers) or groups for short-term stays, and that provides common areas and communal facilities. To be considered a hostel, the property must provide short-term, shared (dormitory-style) accommodation for individual travelers, though many hostels also provide private rooms. The word "dormitory" refers to a room where travelers independently book individual beds in a shared room as opposed to booking entire rooms like in a hotel or guesthouse.
