The system you are referring to is the operating system. The operating system is a software that manages the computer's hardware and software resources, provides common services for computer programs, and allows communication between software applications and hardware devices. It also facilitates the execution of applications and manages input/output operations. Additionally, the operating system includes a supervisor system, which ensures that the system resources are used efficiently and that different programs and processes run smoothly. The input/output system, on the other hand, refers to the software and firmware that enable communication between the computer's hardware and the outside world, such as input devices (keyboard, mouse) and output devices (monitor, printer).
