The area that holds all the startup instructions the computer needs to start is the ROM, or read-only memory.
The answer is B. A only. The optimum valve timing is found through experimentation using an engine dynamometer. The timing of the opening and closing of the valves is called valve timing. So the use of dynamometer measures the power output of a machine that is why it can measure the optimum valve timing.
There is block cipher kind of mode of operation. The block cipher mode of operating requires that both the message sender and receiver is exchanged is the (CTR) Counter.
<h3>What is the Counter (CTR)?</h3>
This is known to be a common block cipher mode of operation. It often needs that both the message sender and receiver to have a kind of access a counter, that helps to computes a new value whenever a ciphertext block is been exchanged.
The disadvantage of CTR is known to be the fact that it needs a synchronous counter necessary for both the sender and receiver.
