ROM is one kind of secondary memory. And you use that memory all the time. The whole OS of your phone resides in the ROM along with all of your images and files (if you're not using external storage obviously).

ROM : Read Only Memory
RAM : Random Access Memory
the first only hold static data (non modifiable) while the second can store data (read/write)
