Return an exception if there is an index out of bound stating “Index out of bound”. ============================= Example 1: Input: list_one = [1, a, 2, 4] list_two =[5, 6, 7, 8] Output: The list has some non number values

Answer:

list_one=[]

list_two=[]

list_three=[]

str1=input("list_one:")

for i in str1:

   if i.isdigit():

       i=int(i)

       list_one.append(i)

   elif i.isalpha():

       list_one.append(i)

str2=input("list_two:")

for i in str2:

   if i.isdigit():

       i=int(i)

       list_two.append(i)

   elif i.isalpha():

       list_two.append(i)

print(list_one)

print(list_two)

if len(list_one)==len(list_two):

   for i in range(len(list_one)):

       multiply=list_one[i]*list_two[i]

       add=str(multiply)

       list_three.append(add)

else:

   print("Index out of bound")

n=0

for i in list_three:

   if i.isdigit():

           n+=1

   else:

       print("The list has some non number values")

print(list_three)

In this scenario, The director of security at an organization has begun reviewing vulnerability scanner results and notices a wide range of vulnerabilities scattered across the company. Most systems appear to have OS patches applied on a consistent basis but there is a large variety of best practices that do not appear to be in place. Thus, to ensure all systems are adhering to common security standards a Network vulnerability database, which typically comprises of security-related software errors, names of software, misconfigurations, impact metrics, and security checklist references should be used.

WHERE YEAR(o.OrderDate) = '1996'

GROUP BY e.EmployeeID,e.FirstName,e.LastName

ORDER BY OrderByEmployee DESC

2. SELECT o.OrderID,c.CustomerID, o.OrderDate,SUM((od.Quantity)*

od.UnitPrice - od.Discount)) as TotalCost FROM Orders o

JOIN [Order Details] od

ON od.OrderID = o.OrderID

JOIN Customers c

ON o.CustomerID = c.CustomerID

WHERE (MONTH(OrderDate)= 7 OR MONTH(OrderDate) = 8) and

YEAR(OrderDate) = 1996

GROUP BY o.OrderID,c.CustomerID, o.OrderDate

ORDER BY TotalCost DESC

3. SELECT c.CustomerID, c.CompanyName, c.City, COUNT(o.OrderID) as TotalOrder, SUM(od.Quantity* od.UnitPrice) as TotalOrderAmount FROM Customers c

JOIN Orders o

ON o.CustomerID = c.CustomerID

JOIN [Order Details] od

ON od.OrderID = o.OrderID

WHERE c.Country = 'USA'

GROUP BY c.CustomerID, c.CompanyName, c.City

Luda [366]

Answer:

Software as a Service (SaaS)

Explanation:

Cloud computing can be defined as a type of computing that requires shared computing resources such as cloud storage (data storage), servers, computer power, and software over the internet rather than local servers and hard drives.

Generally, cloud computing offers individuals and businesses a fast, effective and efficient way of providing services.

Cloud computing comprises of three (3) service models and these are;

1. Platform as a Service (PaaS).

2. Infrastructure as a Service (IaaS).

3. Software as a Service (SaaS).

Software as a Service (SaaS) can be defined as a cloud computing delivery model which involves the process of making licensed softwares available over the internet for end users on a subscription basis through a third-party or by centrally hosting it.

Hence, Software as a Service (SaaS) is an example of a cloud computing environment that provides users with a web based email service. Therefore, if you pay a subscription fee to use an application via the internet rather than purchasing the software outright, the app is called a Software as a Service (SaaS) application.

Some examples of SaaS applications are Salesforce, Google apps, Bigcommerce, Dropbox, Slack etc.
