for what purpose this factory rom /firmware uses?
The main difference is that the single file doesn't Factory Reset the phone after flashing, but the 4 file firmware does factory reset and remove absolutely everything and make it like an out of the box phone.

The 4 files are called Binary Firmware which contains all the files in certain order:
  • BL ,Bootloader contains all the boot files
  • AP Contains all the system and recovery files.
  • Modem/CP contains phone network and wifi software.
  • CSC Contains PIT file and Cache removing IMG which puts all the files in order and repairs any damage firmware has before.
Thats why they are called repair files.
