<h3>What is an i/o system?</h3>
- I/O (Input/Output) is a type of data processing system that sends and receives data from a computer hardware component, device, or network. A network allows data to be sent between devices. Computers would be unable to communicate with other systems or devices if I/O was not present.
- The primary function of an i/o system is processor communication, which includes a variety of tasks such as data transfer between the processor and an I/O module, accepting and decoding commands sent by the processor, reporting current status, and the ability for the I/O module to recognize its own unique address.
- A system call allows a user program to communicate with the operating system. The program requests a number of services, and the operating system responds by invoking a series of system calls to fulfill the request.

echo("The minimum is ".$x." and the maximum number is ".$y);
}
}
MinMax(20,4);
?>
Explanation:
<?php
This defines the user function with two parameters x and y
function MinMax($x,$y) {
This checks if parameter x is greater than parameter y
if($x > $y){
If yes, it prints x as the maximum and y as the minimum
echo("The minimum is ".$y." and the maximum number is ".$x);
}
If otherwised
else{
If yes, it prints y as the maximum and x as the minimum
echo("The minimum is ".$x." and the maximum number is ".$y);
