{{Short description|Computer programs stored in the memory of switching systems which facilitate telephone call connections}}
'''Stored program control''' ('''SPC''') is 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. Stored program control was invented in 1954 by [[Bell Labs]] scientist [[Erna Schneider Hoover]], who reasoned that computer software could control the connection of telephone calls.<ref name=tws2Q312>{{cite news
