Serial Peripheral Interface-SPI

Which of the following statements is true about SPI?

• Serial Peripheral Interface.
• single-wire communication interface protocol.
• It is not used for data transfer in IoT.
• It is used for short-distance data transfer only.

What is the function of a clock signal in SPI communication?

• It synchronizes the data transfer.
• It provides power to the connected device.
• It controls the data transfer speed.
• It is not necessary for SPI communication.

Which of the following devices is commonly used as a slave in SPI communication?

• Sensors
• Actuators
• Microcontrollers
• Single-board computers

In SPI communication, what is the role of the master device?

• It initiates and controls the data transfer.
• It receives data from the slave device.
• It provides power to the slave device.
• It acts as a slave device to receive data from others.

Which of the following is an advantage of using SPI over other communication protocols?

• High data transfer rate.
• Long-distance data transfer capability.
• Can connect multiple devices in a chain.
