Why is the management of different devices that are connected to a computing device a major concern for operating system developers?

• Because all I/O devices require manual configuration by the user.

• Because operating systems must ensure that all devices use the same communication protocol.

• Because I/O devices differ so widely in their functionality and performance.

• Because the number of connected devices is always fixed and cannot change.

What do you call the software components that can be augmented into an OS to handle a specific device?

• Device controllers

• Device drivers

• Operating System

• I/O devices

Which hardware mechanism notifies the client program when an I/O device is ready?

• Polling

• I/O Device

• Interrupt

• CPU

This type of I/O operation causes the program to wait for the operation to complete before proceeding with the next task.

(a)  

What is the process of repeatedly checking an I/O device to see if it’s ready for the next operation?

• Polling

• Client Program

• Interrupt

• CPU

To begin an I/O operation, the starts by loading the registers within the device controller.

(a)  

What is a temporary storage space inside the device controller where data is held before being transferred?

(a)  

This is a type or computer memory that has the capability to hold saved data even if the computer power is turned off.
