1st Answer:
The word "serf" is Latin for slave, so they were slaves. Peasants were not slaves they were tenant farmers working the land for the king and his nobles.
2nd Answer:
The serfs were bound to the soil, meaning that serfs could not move away from the manor on which they lived. The deal was two way, however, and the lord could not make them move away.
By contrast, free peasants were not bound to the soil. They were allowed to move away, but the lord of the manor could also fire them from their jobs and kick them out of their homes.
Serfs and freemen alike paid rent. Freemen were not usually organized the same way serfs were. And the rent they paid was more commonly money, where the serfs' rent was commonly in labor or a share of a crop.
The Latin word for slave was "servus." Deriving a description of the serf of the Middle Ages from a word from ancient Rome is not going to work, even though the word is related. They were different cultures, and the words had different meanings.
because of the serfs
it wasn't.

Serfs and Peasants
Medieval SerfsA medieval village or manor usually contained several classes of laborers, consisting of Medieval Serfs and peasants. There might be a number of freemen, who paid a fixed rent, either in money or produce, for the use of their land. Then there were Medieval Serfs who laboured in the lord's household or at work on his domain. Most of the peasants were Medieval Serfs or villeins. The other labourers were called Cottagers or small holders. Under feudalism the lords and nobles of the land had certain rights over Medieval Serfs and Peasants which included the right of jurisdiction, which gave judicial power to the nobles and lords and the right of hunting
Peasants who were bound to a manor were known as serfs or villeins. They were required to work the land and pay dues to the lord of the manor in exchange for protection and the right to live on the land. Serfs were not free to leave the manor without the lord's permission.
the customs and traditions of the manor
Medieval towns were crowded because serfs wanted more freedom and moved out of the manor land to towns.
Serfs or peasants did manual work. Most of them worked in the fields and barns of a manor. Some worked in forests, and some worked in mines. A few worked in the kitchens, doing cleaning, driving wagons, and so on.
anyone who lived on it besides the serfs (lords,vassals)
A peasant was a small farmer, who might be a serf, a free tenant, or even a yeoman who had his own land. A serf was usually a peasant, but not always. A serf bound to a manor, and was not free to leave it. Aside from being a farmer, serf could also be a laborer of some type. So many peasants were serfs, and most serfs were peasants.
The manor system protects serfs and merchants, that live in manor. Knights allowed peasants to farm land on their large estates. In return the peasants had to give the knights food, goods or other payment.
