Answer:
Explanation:
When you have a single copy, a large number of concurrent updates that are supposed to go to a file may result in the user obtaining incorrect information. This incorrect information obtained them leads to the file being left in an incorrect state. When you have a lot of or multiple copies, then storage waste exist and the various copies might happen not to be consistent with respect one other. In summary, what happens is that
a) Using one copy saves space, but also the change might have an effect on all the users.
b) Using multiple copies avoids eliminates the change problem, while creating its own problems, using more space.

Answer:
A. a series of actions that solve a particular problem.
Explanation:
An algorithm refers to step by step instructions used to fix a problem and they are used for tasks like make calculations and process data. Algorithms are important for computers to be able to process information as they provide the instructions on how a task has to be performed. According to this, an algorithm is a a series of actions that solve a particular problem.
The program is an illustration of the square function.
The square function takes a number, and returns the square of the number; i.e. the product of the number twice.
So, the square function in Python, where comments are used to explain each line is as follows:
#This defines the square function
def square(num):
#This returns the square of the argument
return num**2
#This gets input for the number
num = int(input("Number: "))
#This calculates the square of the number
x = square(num)
#This prints the square
print("Square:",x)
