In software development and quality assurance, what is referred to as Quality of service?

1 answer:

7 0

Answer: Quality of service(QoS) is the parameter of the software development. This signifies about the management of the software resources,eliminating traffic or errors and evaluating the assurance about service quality of software.

There are several features that come under the quality of service feature to determine the software quality such as performance, scalability, service,scalability etc.If the software is evaluated positive on these factors then service quality is considered good which results in appropriate software development.

Given an list of N integers, Insertion Sort will, for each element in the list starting from the second element: Compare the ele

Elena L [17]

Answer:

def insSort(arr):

ct=0;

for i in range(1, len(arr)):

key = arr[i]

j = i-1

while j >=0 and key < arr[j] :

arr[j+1] = arr[j]

j -= 1

ct=ct+1;

arr[j+1] = key

return arr,ct;

print(insSort([2,1]))

Given the following function definition

siniylev [52]

Answer:

B. 1 6 3

Explanation:

Given function definition for calc:

void calc (int a, int& b)

{

int c;

c = a + 2;

a = a * 3;

b = c + a;

}

Function invocation:

x = 1;

y = 2;

z = 3;

calc(x, y);

cout << x << " " << y << " " << z << endl;

Since x is passed by value, its value remains 1.

y is passed by reference to the function calc(x,y);

Tracing the function execution:

c=3

a=3

b=c+a = 6;

But b actually corresponds to y. So y=6 after function call.

Since z is not involved in function call, its value remain 3.

So output: 1 6 3

Which was cited as a reason why Google became so popular?

kupik [55]

Answer:

Google became successful because its founders were well-connected. Google was the world's first and best search engine. Google changed the world by solving an old problem in a new way. Google's other products are now more important to its success than search.

Matlab In this assignment you will write a function that will calculate parallel resistance for up to 10 parallel resistors. Cal

Ket [755]

Answer:

The complete Matlab code along with step by step explanation is provided below.

Matlab Code:

function Req=ParallelR(Number)

Number=input('Please enter the number of resistors: ');

if Number>10 | Number<=0

disp('Invalid input')

return

end

R=0;

for i=1:Number

r=input('Please enter the value of resistor: ');

R=R+1/r;

end

Req=1/R;

end

Explanation:

Parallel resistance is given by

$\frac{1}{Req} = \frac{1}{R_{1}} + \frac{1}{R_{2}} + \frac{1}{R_{3}}...+\frac{1}{R_{N}}$

First we get the input from the user for how many parallel resistors he want to calculate the resistance.

Then we check whether the user has entered correct number of resistors or not that is from 1 to 10 inclusive.

Then we run a for loop to get the resistance values of individual resistors.

Then we calculated the parallel resistance and keep on adding the resistance for N number of resistors.

Output:

Test 1:

Please enter the number of resistors: 3

Please enter the value of resistor: 10

Please enter the value of resistor: 20

Please enter the value of resistor: 30

ans = 60/11

Test 2:

Please enter the number of resistors: 11

Invalid input

Test 3:

Please enter the number of resistors: 0

Invalid input

The difference between the centerline of a vehicle and the line perpendicular to the rear wheels is called what?

snow_lady [41]

The thrust angle is an imaginary line drawn perpendicular to the rear axle's centerline. It compares the direction that the rear axle is aimed with the centerline of the vehicle. It also confirms if the rear axle is parallel to its front axle and that the wheelbase on both sides of the vehicle is the same.
