Answer to Question 1

Three

Answer to Question 2

In comparison to relay logic, solid state components have no moving parts. They are sealed from the atmosphere. They take up less space because most of the components are attached to a compact circuit board. They generally cost less and require less power. Most important, they can be more than 1,000 times faster than relays.
