Datafiles are the repository for data. The size and number of datafiles is unlimited. For a small database, only a few gigabytes might have more than half a dozen datafiles. A larger database could have thousands of datafiles, whose size is limited only by the capabilities of the host operating system and hardware.
For definition purposes, datafiles are the physical structures visible to the system administrators. Logically, they are the repository for the segments containing user data that the programmers see, and also for the segments that make up the data dictionary.
