Como o Sistema Operacional abstrai o uso dos dispositivos de E/S? Quais são os dois tipos de dispositivos de E/S manipulados pelo Sistema Operacional?

Unclear question. But I inferred this to be the clear rendering;

How does the Operating System abstract the use of I / O devices? What are the two types of I / O devices handled by the Operating System?

Explanation:

Although the question lacks details about the operating system in question let's assume it is referring to Windows.

Some are common examples of I/O (input/output) devices to select from:

1. Mouse - input

2. Keyboard - input

3. Monitor screen - output

4. Printer - output

5. Joystick - input
