Question 45

What is correct about the following description of device management in the operating system?

Options:

The main task of port device management is to complete the I/O requests made by users and classify I/O devices for users.

Whenever a process makes an I/O request to the system, as long as it is secure, the device allocator will assign the device to the process according to a certain policy.

Device management can virtualize a physical device into multiple logical devices through virtualization technology, providing multiple user processes to use.

In order to alleviate the problem of speed mismatch between CPU and I/O devices and improve the parallelism of CPU and I/O devices, in modern operating systems, almost all I/O devices are exchanging numbers with processors

Buffers are used at all times.
