CA 5-6 UNITS QUIZ

Why is an interface needed to connect peripheral devices to a computer?

• To increase CPU speed

• To provide a standardized communication method

• To reduce memory usage

• To directly execute I/O commands

In synchronous data transfer, data transfer is dependent on:

• The availability of the CPU

• A clock signal

• Device polling

• Device priority

Which method uses a signal sent by the peripheral to notify the CPU when it is ready for data transfer?

• Strobe-Controlled Transfer

• DMA Transfer

• Handshaking

• Polling

Which data transfer method allows the CPU to execute other instructions while the peripheral device and memory communicate directly?

• Programmed I/O

• Strobe-Controlled Transfer

• Interrupt-Initiated I/O

• DMA Controlled Transfer

In an interrupt-initiated I/O, the CPU:

• Continuously checks if a device is ready

• Receives an interrupt signal when the device is ready

• Ignores any I/O requests

• Uses direct access to memory for I/O

Which method determines device priority by a linear chain of devices?

• Polling

• Handshaking

• Priority Interrupt

• Daisy Chaining

An Input/Output Processor (IOP) is primarily designed to:

• Control the arithmetic unit

• Manage communication with I/O devices

• Execute application software

• Store program instructions

Which of the following correctly describes a bus system in a computer?

• It provides a pathway for data and control signals between components

• It is used only for memory communication

• It connects the CPU to storage devices only

• It is solely dedicated to input devices

Which type of bus is specifically responsible for carrying memory addresses?

• Data Bus

• Control Bus

• Address Bus

• System Bus

The principle of parallel processing allows a system to:

• Execute multiple instructions simultaneously

• Store more data

• Increase clock speed

• Decrease power usage
