Answer:
disk caching
Explanation:
Hi,
Magnetic hard drives use disk caching to speed up performance. This method is quite ingenious because what it does is that in a section of memory in your pc, it keeps a copy of information that was previously accessed in the hard disk. So, next time if the same data is requested, the system can refer to cache to get quick access rather than going to the hard disk (which is slower).
Explanation:
A computer keyboard is an input device that allows a person to enter letters, numbers, and other symbols (these are called characters in a keyboard) into a computer. It is one of the most used input devices for computers. Using a keyboard to enter lots of data is called typing
Answer:
The solution is implemented using C++
int getRowTotal(int a[][5], int row) {
int sum = 0;
for(int i =0;i<5;i++)
{
sum += a[row][i];
}
return sum;
}
Explanation:
This defines the getRow function and the parameters are arr (the 2 d array) and row and integer variable
int getRowTotal(int arr[][5], int row) {
This defines and initializes sum to 0
int sum = 0;
This iterates through the row and adds the row items
<em> for(int i =0;i<5;i++) {
</em>
<em> sum += arr[row][i];
</em>
<em> }
</em>
This returns the calculated sum
return sum;
}
