Answer:

C. Hardware resources are dynamically allocated as use increases.

Explanation:

Cloud computing is a technique organisations to store and retrieve resources in a remote central database with secure access over the internet. It is able to access large data storage resources that would have cost more if they had implemented one for themselves.

A database or data centre is a online group of servers that is in a subscribed service to authorised users. Storage hardware allocation is dynamic to users, which means that another storage location in issued on every duration of subscription, making it easy to add more storage infrastructure. This defines the scalability of data centres.

The scheme function (mult2-diff Ist) should take one argument, a list of numbers, and results in multiplying each number in the
JulijaS [17]

Answer:

The solution code is written in Python.

  1. def mult2_diff(lst):
  2.    num_list = []
  3.    for x in lst:
  4.        num_list.append(x * 2)
  5.    diff = num_list[0]
  6.    for i in range(1, len(num_list)):
  7.        diff = diff - num_list[i]
  8.    
  9.    print(diff)

Explanation:

Firstly, based on the requirement stated in the question, define a function <em>mult2_diff() </em>that takes one argument, <em>lst</em>, which is a list of numbers (Line 1).

This function is expected to multiply each number in the list by two and then followed with computing the difference. To do so, let's try to attempt the first function task, multiplying numbers.  Create a new list, num_list, to hold the multiplied numbers (Line 2). Use a for loop to traverse through each number in the input list, <em>lst</em>, and multiply each of them by two and add it to the <em>num_list </em>(Line 4-5).

To attempt the second function task, create another variable, <em>diff</em>, to hold the value of calculated difference between the numbers in the <em>num_list</em>. Initialize <em>diff </em>with the first number in the <em>num_list</em>. Use a another for-loop to traverse through each number in the num_list starting with second index, <em>1</em>, and calculate the difference between the <em>diff </em>and the current number extracted from the <em>num_list </em>through indexing.

At last print the output of <em>diff</em> (Line 11).
