Crank Hubs

what does sealed mean on a bike ?
like sealed cranks, hubs and stuff like that as much detail would be great thx. the meaing
that means the bearings are enclosed into a cylindrical piece that just pops into place, rather than unsealed which you have to grease and place each bearing into the bearing cups.
