'''Stored program control''' (SPC) was a telecommunications technology used for [[telephone exchanges]] controlled by a computer program stored in the memory of the switching system. SPC was the enabling technology of [[electronic switching system]]s (ESS) developed in the [[Bell System]] in the 1950s, and may be considered the third generation of switching technology.
