Answer:
Quality assurance testing plays a very crucial role in the process of software development. It saves money and time by spotting bugs and errors early in the software development life-cycle. Software that is newly developed may have inconsistencies, redundancies, and flaws; therefore, proper QA testing is mandatory.

b. IT infrastructures and services
Explanation:
IT infrastructure or information technology infrastructure refers to the various components involved in the functioning of an IT enabled operations. These components include; hardware, software, network resources, etc.
It is usually internal to an organization and deployed within the confines of its own facilities.
Answer:
I am writing the function using Python. Let me know if you want the program in some other programming language.
def iterPower(base, exp):
baseexp = 1
while exp > 0:
baseexp = baseexp*base
exp= exp - 1
return baseexp
base = 3
exp = 2
print(iterPower(base, exp))
Explanation:
- The function name is iterPower which takes two parameters base and exp. base variable here is the number which is being multiplied and this number is multiplied exponential times which is specified in exp variable.
- baseexp is a variable that stores the result and then returns the result of successive multiplication.
- while loop body keeps executing until the value of exp is greater than 0. So it will keep doing successive multiplication of the base, exp times until value of exp becomes 0.
- The baseexp keeps storing the multiplication of the base and exp keeps decrements by 1 at each iteration until it becomes 0 which will break the loop and the result of successive multiplication stored in baseexp will be displayed in the output.
- Here we gave the value of 3 to base and 2 to exp and then print(iterPower(base, exp)) statement calls the iterPower function which calculates the exponential of these given values.
- Lets see how each iteration works:
baseexp = 1
exp>0 True because exp=2 which is greater than 0
baseexp = baseexp*base
= 1*3 = 3
So baseexp = 3
exp = exp - 1
= 2 - 1 = 1
exp = 1
baseexp = 3
exp>0 True because exp=1 which is greater than 0
baseexp = baseexp*base
= 3*3 = 9
So baseexp = 9
exp = exp - 1
= 1-1 = 0
exp = 0
- Here the loop will break now when it reaches third iteration because value of exp is 0 and the loop condition evaluates to false now.
- return baseexp statement will return the value stored in baseexp which is 9
- So the output of the above program is 9.
Answer:
Reflection
Explanation:
Reflection is the property of light in which when a ray of light hits a smooth surface, it bounces back in the direction in which it came from. If i is the angle between the normal to the surface and the incident ray, and r is the angle between the normal and reflected ray, the law of reflection states that the angle of incidence equals the angle of reflection. That is, i = r.
So, to record the image of an object with a camera, one property of light that makes that possible is reflection because, the incidence rays form an image of the object in the camera, while the reflected rays reflect the image so that it is visible to the eye.
I think it should be Java of package instead
