You can format a drive without a partition table, and still
format/use it. I am not sure if it would get automatically mounted,
but it does work. A partition table, and partition will NOT be
created for you. Also, you can have a drive with one partition
without that partition being partition 1. ZIP disks were famous for
this. For a log time, DOS formatted ZIP disks used partition 4.

Nope - A file system is created on a device. Both /dev/sdb and
/dev/sdb1 are devices. For that matter, a device is also a file. You
can use an entire drive, or a partition on a drive, as a tar
archive. (tar -cvf /dev/sdb /home/mikkel)

Remember - under UNIX type systems, everything is a file - that
includes devices. That is why commands like cp and cat work on
drives, as well as what most people consider files.
