Ans:if power supply is turned off the content will be erase for the both case of RAM and EEPROM

Ridha SAIDANI

The correctly reponse is C.

The EEPROM is a special type of memory not contained in all microcontrollers. Its contents may be changed during program execution (similar to RAM ), but remains permanently saved even after the loss of power (similar to ROM). It is often used to store values, created and used during operation (such as calibration values, codes, values to count up to etc.), which must be saved after turning the power supply off. A disadvantage of this memory is that the process of programming is relatively slow. It is measured in miliseconds.

In my knowledge the correct answer is D , both the RAM and the EEPROM are erasable memories.

The Correct Answer is ‘B’ the RAM as RAM is considered volatile memory

I find the answer is B. EEPROM is another type of ROM but is erasable. ROM retains its memory even when power is off, hence it contains the OS boot files.

The answer is C, Because it is Erasable Programmable Memory. hence if the power once get off and resume back previous program will be erased. We can over write the other  program.

Random Access Memory as it is volatile and data is lost  once power is out.
