There's no functional difference: the .iso image is exactly the same.
An install from a physical CD/DVD boots from the boot sector there:
an install from a flash drive to which the image is copied boots from that.

This has been covered in detail on debian-user in various posts to/from you
and replies there.
If you use a physical DVD: at one point in the install, it asks if you want
to add another CD/DVD. If you physically eject the DVD at that point and
put in a second DVD, the installer will read the index files from a second
or subsequent DVD. That's _exactly_ the same as "apt-cdrom add"
If you install from a single DVD image on a flash drive - you can complete
the minimal command line GUI-less install without using the network.
In order to access the first DVD .iso on a flash drive afterwards, you need to use
loop mount - that allows you to "read down" to the .iso file system, as
it were.
If you have several CD/DVD images on one flash drive - you can mount any of them
using loop mount, use apt-cdrom add to add them and install files from them.
If you have a complicated install like GNOME and several other packages, you
may be prompted to "insert" DVD2, DVD3 - loop mount them to the appropriate
mount point - probably /media/cdrom -and then install from them.
If you use one of the larger images - the 16G iso image / the BD images -
those are equivalent to a "large DVD" and can be written to media / a flash
drive. To create those, you (or someone else you trust) will need to use
jigdo files to build them because we don't routinely distribute images of
those sizes. It will act effectively as a large DVD.
Ask whoever provided you with phsyical DVDs to provide the files on a
USB stick?
