Answer:
1.Buddhist monasteries are generally called vihara (Pali language el). Viharas may be occupied by men or women, and in keeping with common English usage, a vihara populated by females may often be called a nunnery or a convent. However, vihara can also refer to a temple.
2.A cathedral is a church that contains the cathedra (Latin for 'seat') of a bishop, thus serving as the central church of a diocese, conference, or episcopate.
