Which of the following is a human-readable peripheral device? A) Magnetic disk B) Sensor C) Printer D) Actuator

C) Printer

Fill in the blank: The I/O module performs two major functions: interface to the processor and memory via the system bus and interface to one or more peripherals by ______.

Tailored data links

True or False: Peripherals are directly connected to the system bus without any intermediary.

False. Peripherals are not directly connected to the system bus; an I/O module is used for communication.

What is the primary function of a transducer in the context of peripheral devices?

To convert data from electrical energy to other forms during output and from other forms to electrical during input.

Riddle: I reside between the CPU and peripherals, ensuring smooth communication, while managing control signals and data transfer. What am I?

I/O Module

Which I/O transfer mode requires continuous CPU monitoring and is less efficient? A) Interrupt Driven I/O B) Direct Memory Access C) Programmed I/O D) Cycle Stealing

C) Programmed I/O

Fill in the blank: The I/O interface resolves differences in _____ between the CPU and peripheral devices.

Data transfer rates

True or False: In memory-mapped I/O, distinct input and output instructions are used for device communication.

False. Memory-mapped I/O does not use specific input or output instructions; the same memory reference instructions are used.

What is the role of the DMA controller during data transfer?

To manage data transfers directly between memory and I/O devices without CPU involvement.

Riddle: I can transfer large blocks of data without CPU intervention, freeing the processor for other tasks. What am I?

Direct Memory Access (DMA)
