Catholic Answer
A bishop is a successor of the Apostles, he has received the fullness of Christ's priesthood. His most distinctive and unique role is ordination - to ordain priests and other bishops. In most cases, a bishop is in charge of a diocese, even if it is only titular - there are over two thousand ancient Catholic dioceses and archdiocese which have been destroyed by the Moslems; the titles are now given to auxiliary, coadjutor, and other Bishops who do not have a residential see.
A Bishop may only ordain another Bishop with express permission from the reigning Pope. The Bishop is the head and fullness of the Catholic Church in his diocese, he wears a ring to symbolize his authority and carries a shepherd's staff for the same reason.
The Bishop is the automatic head in the local church of the diocese or archdiocese. While the priest, he is the head in a particular parish under the authority of the Bishop.
The key differences between the roles and authority of a bishop and a pope in the Catholic Church are that bishops oversee specific regions or dioceses, while the pope is the leader of the entire Catholic Church worldwide. Bishops have authority within their dioceses, while the pope has ultimate authority over all bishops and the Church as a whole.
Only the pope can appoint a bishop in the Catholic Church.
