Answer:
The solution code is written in Python:
- def square(num):
- if type(num).__name__ == 'int':
- sq_num = num * num
- return sq_num
- else:
- return "Invalid input"
-
- print(square(5))
- print(square("Test"))
Explanation:
To ensure only certain type of operation can be applied on a input value, we can check the data type of the input value. For example, we define a function and name it as <em>square</em> which take one input number, <em>num </em>(Line 1).
Before the <em>num</em> can be squared, it goes through a validation mechanism in by setting an if condition (Line 2) to check if the data type of the input number is an integer,<em> int.</em> If so, the<em> num </em>will only be squared otherwise it return an error message (Line 6).
We can test our function by passing value of 5 and "Test" string. We will get program output:
25
Invalid input

Answer / Explanation
To answer this question, let us first understand what a multi boot environment is and what an environment using a hypervisor is:
Multiple-booting can be defined or simply refers to the process of installing different multiple operating system on a single computer and also to be able to determine which of the operating systems boot per time.
While:
Hypervisor or a type 2 hypervisor can be described as a form of virtual machine in form of a software that is installed on in an existing operating system of a computer. One of the main benefit of an hypervisor is it enables easy navigation of guest on your computer without actually navigating into your original or primary operating system plus it aid in fast system recovery.
If we now refer back to the question asked in respect to which i would offer as the most convenience, i would prefer the type 2 hypervisor as convenient because i am able to run an operating system inside another operating system so navigating between two operating system would be very easy as compared to the Multi-booting where i have to always shut down an operating system to navigate between the operating system because i can only use one operating system per time.
The answer would be B because ".edu" stands for education and it shows there was a source for the information
