Alter boys

An altar server is a lay assistant to a member of the clergy during a religious service. An Alter server attends to supporting tasks at the altar such as fetching and carrying, ringing the altar bell, etc.Formally, and still in traditional catholic orders (FSSP, ICTK, SSPX, etc) only young men, among whom the Church hoped to recruit for the priesthood, and seminarians, who need the training, are alter servers; and thus altar boy was the usual term until Canon 230 was changed with the promulgation the code of Canon Law in 1983 which provided the option for females to serve at the altar.
The term altar server is now widely used and accepted due to this. An Acolyte is one of the minor orders which is ordained by a Bishop. The title of Acolyte is still only given to men as it is an ordained minor order. This term is now usually reserved for the ministry that all who are to be promoted to the diaconate, whether permanent or transitory, must receive at least six months beforehand (canon 1035 of the Code of Canon Law).The Roman Rite of the celebration of Mass, Acolytes have the following responsibilities (depending which type of mass) during

Preparation of the chalice: Acolytes present the cruets of water and wine for the Deacon or Priest to pour in the chalice. Lavabo: An Acolyte administers the water to the Priest as he ritually washes his hands. Beginning of the Sanctus: Altar bell is rung thrice. Canon of Mass: When the Priest extends his hands over the chalice, Acolytes ring altar bell once, stand, take the bell, without genuflecting kneel on either side of the Priest. Consecration: At each Consecration Acolytes make a deep bow at the Priest’s first genuflection, and ring the bell once. During each Major Elevation, Acolytes kneel erect, raising the back of the chasuble and ringing the bell thrice. During the Priest’s second genuflection, Acolytes release chasuble, make a deep bows and ring the bell once. After theConsecration, holding the bell, Acolytes return to their posts and kneel. Post Agnus Dei: Acolytes get patens from credence table and go back to posts with genuflections and kneeling. When the Priest genuflects and says the triple "Domine, non sum dignus..." Acolytes ring the bell thrice.
