<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.
