Subtraction is accomplished in computers by the R’s complement and add method. R’s complement subtraction allows us to use fewer circuits than would be required for separate add and subtract functions.
True
False
What type of logic gates are added to a parallel adder to enable it to subtract?

The R-S Flip-Flop is used to temporarily hold or store information until it is needed.
True
False
Which of the following is a R-S Flip Flop?
Which of these symbols represent a R-S Flip Flop with inverted inputs?
Which of these symbols represents a toggle flip flop?
The R-S FF is the most widely used FF because of its versatility.
True
False
Identify this circuit:
Adder

Flip Flop
None of the above
Clocks are designed to provide the most efficient operation of the equipment. During the design phase, the frequency, pulse width, and the number of phases required is determined; and the clock circuit is built to meet those requirements.
True
False
A counter is simply a device that counts. Counters may be used to count operations, quantities, or periods of time. They may also be used for dividing frequencies, for addressing information in storage, or for temporary storage.
True
False

Flip Flop
Counter
Adder
A decade counter is a binary counter that is designed to count to 1010.
True
False
Which of the following circuits is a down counter?
A register is not a temporary storage device.
True
False
Parallel registers are designed to receive or transfer all bits of data or information simultaneously. Which of these circuits is a parallel register?
This integrated circuit best describes which of the following circuits?
