Explain Stored Program Control.
Stored Program Control: Modern digital computers utilize the stored programmed idea. Now, a program or a set of instructions to the computer is stored into its memory and the instructions are automatically executed one by one through the processor. Continuing the exchange control functions by programs stored in the memory of a computer lead to the nomenclature stored program control (SPC). An instant consequence of program control is the introduction of a variety of new facility to users and full-scale automation of exchange functions. Common Channel Signaling (CCS), centralized preservation and automatic fault diagnosis as well as interactive human-machine interface are several of the features which have become possible because of the application of SPC to telephone switching.
