Why is it important to use flip-flops instead of latches to construct a finite state machine?
a. flip-flops are the only way to provide the speed necessary for reliable finite state machine operation.
b. the reduced speed of flip-flops is necessary to ensure reliable finite state machine operation.
c. flip-flops cost less than latches, so you have to use flip-flops to obtain the most economical implementation possible.
d. flip-flops use less power than latches, so their use is important for optimizing battery life.
e. flip-flops will never change state more than once per clock cycle, which is essential for designs like finite state machines where the outputs of the machine feed back into the inputs.

The answer are letters D and E.

Explanation:

Because, Flip-flops use less power than latches, so their use is important for optimizing battery life.  Flip-flops will never change state more than once per clock cycle, which is essential for designs like finite state machines where the outputs of the machine feed back into the inputs.

answer; i believe the correct answer is (a) all trenches must have access/egress;

yes we can change both the color of the value of a cell as well as background color of a cell at the same time .

as we know that excel sheet consists of columns and rows.

and intersection of column and row is called cell.

we can change color of the cell and background of the cell at the same time.

hence the statement that

can a person change color of the cell and background of the cell at the same time is true.
