Answer:
A AND B= 1 or 0
1 1 1
0 1 0
1 0 0
0 0 0
So, as explained above if both are 1 we then only get 1, or else we get 0 always in case of AND which is a logical operator, whose output can be 0 or 1 only. This is being depicted above.
Explanation:
If both are 1 we get 1 or always else, we get the output =0.
Answer:
It's the <u><em>power supply</em></u>
Explanation:
The power supply is what essentially enables the computer to operate. It is able to do that by converting the incoming alternating current (AC) to direct current (DC) at the correct wattage rating that is required by the computer to function. The power supply is a metal box that is generally placed in the corner of the case.
Answer:
xyz = 25
result = square(xyz)
print(result)
The above code assigns the value 25 to variable xyz as 5*5=25. Then next statement is a function call to square() function passing xyz to this function in order to compute the square of 25. The output is:
625
Explanation:
The above code can also be written as:
xyz = 5*5
result = square(xyz)
print(result)
The difference is that xyz is assiged 5*5 which is equal to 25 so the output produced will be the same i.e. 625.
The result variable is used to store the value of square of 25 after the square() method computes and returns the square of 25. So print(result) prints the resultant value stored in the result variable i.e. 625
Answer:
// A optimized school method based C++ program to check
// if a number is composite.
#include <bits/stdc++.h>
using namespace std;
bool isComposite(int n)
{
// Corner cases
if (n <= 1) return false;
if (n <= 3) return false;
// This is checked so that we can skip
// middle five numbers in below loop
if (n%2 == 0 || n%3 == 0) return true;
for (int i=5; i*i<=n; i=i+6)
if (n%i == 0 || n%(i+2) == 0)
return true;
return false;
}
// Driver Program to test above function
int main()
{
isComposite(11)? cout << " true\n": cout << " false\n";
isComposite(15)? cout << " true\n": cout << " false\n";
return 0;
}

Answer:
B) ERP systems
Explanation:
ERP which means Enterprise Resource Planning is a software that uses a centralized database, it helps to hasten business processes thereby reducing the use of manual labour. Some of the integrated software modules which it provides are:
*Finance, Accounting.
*Human resource.
*Manufacturing and production.
*Sales and marketing.
The ERP system does not really need the total involvement of a human because it has a database where information stored is used in the daily execution of tasks, it can also be used to measure the productivity and profitability of the business.
