Ask help:what does entry-point address mean in a ELF-64 file?


I am trying to understand the ELF file, I use readelf utility to read
an ELF file, in the result, there is entry-point address displayed. I
searched on the Internet, it says its a virtual address. My question
is could two program have the same entry-point address(if I compile
hello1.c,then compile another hello2.c)? How does the loader map this
virtual address to the physical address?

Thanks a lot for any comments!!
