Answer:
20
Explanation:
During the first iteration for the list [1, 4], numB = 1.
During the first iteration of the list [2, 3], numA = 2.
answer = answer + numA + numB
= 0 + 2 + 1
= 3
Since the list [2, 3] is in a nested loop, we need to first finish iterating the whole list before numB iterates to the next number, so numA = 3 this time and numB still stays at 1.
answer = answer + numA + numB
= 3 + 3 + 1
= 7
Now, numB moves to 4 and numA starts back at 2 again.
answer = answer + numA + numB
= 7 + 2 + 4
= 13
numB still says at 4 and numA moves to 3 since it is in a nested loop:
answer = answer + numA + numB
= 13 + 3 + 4
= 20
print(answer) will print the output 20.

Answer:
Central processing unit (CPU)
Explanation:
A computer can be defined as an electronic device that is capable of receiving of data in its raw form as input and processes these data into information that could be used by an end user.
The central processing unit (CPU) is typically considered to be the brain of a computer system. It is the system unit where all of the processing and logical control of a computer system takes place.
Hence, the most important component in a computer is the central processing unit (CPU) because without it, it is practically impossible for the computer to run any software application or program.
Additionally, the component of the central processing unit (CPU) that controls the overall operation of a computer is the control unit. It comprises of circuitry that makes use of electrical signals to direct the operations of all parts of the computer system. Also, it instructs the input and output device (I/O devices) and the arithmetic logic unit on how to respond to informations sent to the processor.
