Operating System - I/O

It is a I/O mechanism where the peripheral devices directly connects with the memory without the CPU intervention

In I/O devices one of the bus control lines is dedicated for this purpose and is called the _______.

Not a type of I/O Device

I/O Device Feature: Used by the CPU to control the device.

A DMA Mode of Operation where the controller uses a more organized approach in transferring block of data.

Memory and CPU are connected with the same bus called the System Bus or I/O Bus.

any hardware that allows a human operator or other systems to interface with a computer.

Devices communicate with the CPU through:

is a hardware interrupt that doesn’t have an actual source (false alarm).

1 Function of a Device Driver

Which of the following is not a type of commonly used I/O mechanisms?

It alerts the processor to a high-priority process requiring interruption of the current working process.

The execution of applications depends not only on the CPU and memory but also on various other hardware components.

Special software program is used as a method or rules which helps in transferring of information between CPU and Device.

Traps and exceptions are other names for hardware interruptions.

A DMA Mode of Operation where the controller takes control of the memory bus and transfers a block of data in one go.

Common interconnect used in many systems for devices like graphics cards and network adapters.

The _________ takes over the buses to manage the transfer directly between the I/O devices and the memory unit.

Which of the following applications is NOT the reason on why we have DMA?

Which of the following is not a Network Device
