Answer:
Increased processor speed and multi core technologies.
Explanation:
The development of processors over the years is overwhelmingly fast. The CPU use to be cumbersome, expensive and computational speed was moderate.
As it evolves, the CPU was minimized to give rise to microprocessors.
Microprocessors are very fast, running millions of processes on its core. The multiple core processors helped to increase the speed of these processors.
When there are more than one core in a processor (dual, quad or octal core), it processes data in parallel reducing the time of execution compared to a one core processor.
A company having computers with single core would need to upgrade to a new computer with multi core processor to promote speed in data processing.

See explaination
Explanation:
StackExample.java
public class StackExample<T> {
private final static int DEFAULT_CAPACITY = 100;
private int top;
private T[] stack = (T[])(new Object[DEFAULT_CAPACITY]);
/**
* Returns a reference to the element at the top of this stack.
* The element is not removed from the stack.
* atreturn element on top of stack
* atthrows EmptyCollectionException if stack is empty
*/
public T peek() throws EmptyCollectionException
{
if (isEmpty())
throw new EmptyCollectionException("stack");
return stack[top-1];
}
/**
* Returns true if this stack is empty and false otherwise.
* atreturn true if this stack is empty
*/
public boolean isEmpty()
{
return top < 0;
}
}
//please replace "at" with the at symbol
Note:
peek() method will always pick the first element from stack. While calling peek() method when stack is empty then it will throw stack underflow error. Since peek() method will always look for first element ffrom stack there is no chance for overflow of stack. So overflow error checking is not required. In above program we handled underflow error in peek() method by checking whether stack is an empty or not.
A computer system is a combination of software and hardware that links two different types of networks
Answer:
The System Software (Operating System)
Explanation:
Examples of Operating Systems are Windows, MAC and Linux, these software are the foundation of every PC and manages all computer's resources
