Did not get about Function Points ?

I did not get about EI, EA and EQ. How you wrote PI, M and N/A. Kindly explain this complete data function in very detail with atleast one example. I am really thankful to you

EI, EO and EQ are transaction functions in any system and these functions are used to handle the user's need to access data. These functions have been explained in Video lecture no.8 in detail. Therefore, I will recommend you to watch video lecture carefully.

For your additional reading, I am providing a link below which explains each of these transaction functions with examples.
