Answer:
1- Computer hardware includes the physical parts of a computer, such as the case, central processing unit (CPU), monitor, mouse, keyboard, computer data storage, graphics card, sound card, speakers and motherboard. By contrast, software is the set of instructions that can be stored and run by hardware.

The connection will be available on the computer and internet will start working normally.
Answer:
#include <bits/stdc++.h>
using namespace std;
int main() {
int A[3][3],B[3][3],res[3][3],i,j;
srand(time(0));//for seed.
for(i=0;i<3;i++)
{
for(j=0;j<3;j++)
{
int val=rand()%100+1;//generating random values in range 1 to 100.
int val2=rand()%100+1;
A[i][j]=val;
B[i][j]=val2;
}
cout<<endl;
}
for(i=0;i<3;i++)
{
for(j=0;j<3;j++)
{
res[i][j]=0.5*A[i][j]+3*B[i][j];//storing the result in matrix res.
}
}
cout<<"Matrix A is"<<endl;
for(i=0;i<3;i++)
{
for(j=0;j<3;j++)
{
cout<<A[i][j]<<" ";//printing matrix A..
}
cout<<endl;
}
cout<<"Matrix B is"<<endl;
for(i=0;i<3;i++)
{
for(j=0;j<3;j++)
{
cout<<B[i][j]<<" ";//printing matrix B..
}
cout<<endl;
}
cout<<"The result is"<<endl;
for(i=0;i<3;i++)
{
for(j=0;j<3;j++)
{
cout<<res[i][j]<<" ";//printing the result..
}
cout<<endl;
}
return 0;
}
Output:-
Matrix A is
13 95 83
88 7 14
24 22 100
Matrix B is
11 13 95
48 35 20
68 100 18
The result is
39.5 86.5 326.5
188 108.5 67
216 311 104
Explanation:
I have created 2 matrices A and B and storing random numbers int the matrices A and B.Then after that storing the result in res matrix of type double to store decimal values also.Then printing the res matrix.
