Answer

Correct option: (iv) Transformer

Explanation

Embedded systems commonly use different types of memory and storage devices, including:

  • EEPROM: Non-volatile memory used for storing configuration data and calibration values.
  • SRAM: Fast volatile memory used for variables and temporary runtime data.
  • SD card: Removable non-volatile storage suitable for large amounts of logged data.

A transformer is an electrical power/isolating component. It is not a data-storage device.

Therefore, the correct answer is (iv).
