Question

Quizplus · Accepted Answer

The operating system of a PLC is typically stored in non-volatile memory, such as ROM, which retains the stored data even when the device is powered off. RAM and EEPROM are both volatile memory types that would not be suitable for storing the operating system, and while flash memory is non-volatile, it is typically used for storing user programs and data rather than the operating system.
