Answer: C) A model of software distribution. Instead of simply selling an application, the vendor hosts the applications and offers access for a small subscription fee.
Explanation: Software as a service(SaaS) is the cloud computing service that is used as software distribution model .It functions by delivering the applications that are hosted by the third-party over the internet towards the customers.It function on the basis of servers of Saas provider.
Other options are incorrect because users don't log into the workstation directly. This model does not provides security regarding the confidential digital data.
It does not ensure the information service available to the user as per requirement.Thus, the correct option is option(c).
Answer: Yes, it is a possibility, and yes again, marbles can do what a calculator can do already
Answer:
Encapsulation.
Explanation:
Information hiding involves using private fields within classes and it's a feature found in all object-oriented languages such as Java, Python, C#, Ruby etc.
In object-oriented programming language, a process known as encapsulation is used for the restrictions of the internal data of a software program from the outside code, therefore preventing an unauthorized direct access to the codes. This is achieved through the use of classes.
In Computer programming, class members can be defined as the members of a class that typically represents or indicates the behavior and data contained in a class.
Basically, the members of a class are declared in a class, as well as all classes in its inheritance hierarchy except for destructors and constructors.
In a class, member variables are mainly known as its attributes while its member function are seldomly referred to as its methods or behaviors.
One of the main benefits and importance of using classes is that classes helps to protect and safely guard their member variables and methods by controlling access from other objects.
Therefore, the class members which should be declared as public are methods and occasionally final attributes because a public access modifier can be accessed from anywhere such as within the current or external assembly, as there are no restrictions on its access.
Answer:
1. No 'Then' in the if statement
2. No syntax error.
3. No closing if statement that is no "END IF"
4. No syntax error
5. No syntax error
Explanation:
1. The syntax for writing if statement in visual basic is:
If condition Then
'Stament block'
End If
From the above syntax, we see that the "Then" keyword is missing in the snippet.
2. This is okay as there is no syntax error.
str was declared as a string and a variable was assigned to it. Then, intLength was also declared as integer and the length of str is assigned to it.
3. The syntax for writing if statement in visual basic is:
If condition Then
'Stament block'
End If
From the above we can see that "End If" is missing in the given snippet.
4. There is no syntax error. The opening if and ending if are present.
5. There is no syntax error. The general form of writing a select case statement in Visual basic is:
Select Case VariableName
Case 1
"Statement to execute"
Case 2
"Statement to execute"
Case Else
"Default Statement to execute if other case fail"
End Select
