The virtual machine has its own internal file system stored in its virtual disk. Other devices such as the Internet connection, CD-ROM, etc. are used as long as they are available in the physical machine. Remember that if the virtual machine is not connected to Internet, it is highly probable that the physical machine is not connected either. Often times, you need to transfer files between the file system in the virtual machine and the file system in the physical machine.
