What does water softener regeneration mean?

Regeneration is the process of restoring the softening ability of the resin which is inside the water softener unit.
 
Water is softened in an ion exchange process where sodium ions are exchanged for calcium and magnesium. When the sodium ions are all used up, the softening resin becomes exhausted so the water softener then 'regenerates' the resin with brine (salty water) and the calcium and magnesium are exchanged for sodium.
 
The resin is then flushed with water and cleaned back to its original softening state.
