In what way is program control superior to wired control, Electrical Engineering

Q. Classify switching systems. In what way is stored program control superior to hard wired control?

Ans:

Classifications of switching systems are givenin block diagram below:

The SPC gains superiority over hard wired due to following points:

SPC	Hard Wired Control
Flexible	Not Flexible
Slower	Faster
More expensive for moderate processing functions	Less expensive for Moderate, simple and fixed Processing functions
Easier to implement, Complex Processing functions	Difficult to implement, Complex processing functions
Introducing new services is easy	Introducing new services is not easily possible
Easier to maintain	Difficult to maintain
