synchronous up down counter

1.In an UP-counter, each flip-flop is triggered by:

a: The output of the next flip-flop b: The normal output of the preceding flip-flop c: The clock pulse of the previous flip-flop d: The inverted output of the preceding flip-flop

2.In digital logic, a counter is a device which

a: Counts the number of outputs b: Stores the number of times a particular event or process has occurred c: Stores the number of times a clock pulse rises and falls d: None of the Mentioned
