Answer:
The output of this question is 21. As show in the image
The explanation is given in below
Explanation:
Let first write the question
C=1
sum = 0
while(C<10):
C=C+3
sum=sum + C
print(sum)
Now Focus on
while(C<10):
C=C+3
sum=sum + C
The value of C is initially 1
C=1+3
Sum= 0+4
In second loop the value of C will become 4
c=4+3
sum=4+7
In third loop the value of C will be 7
c=7+3
sum=11+10
so the answer is 11+10=21

Answer: Memory hierarchy is the hierarchy that is created on the basis of the response time of different memories. The performance obtained by the memory helps in creating a computer storage space in distinguished form. The factors considered for the creating of the hierarchy structure are usually response time, storage capacity, complexity etc.
Usage of different kind of memories take place due to different kind of requirements from the system which cannot be fulfilled using one memory device.The requirement is based on saving time, decreasing complexity , improving performance etc.Example of requirements can be like some functions and files do not require much space , some might require quick accessing,etc.
Thus hierarchy of any particular system is in the form of fast to slow order from registers,cache memory, Random access memory(RAM) and secondary memory.
