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

you have to email it to yourself from your phone then download it to either google drive or you computer files. then you can go to where ever you saved it and select it and then copy and paste it. or you could attach it to your question when you are writing it which would be much easier. for example: go to the attachment.
