/dev/fd0 - device file representing the drive you would be mounting

/floppy - the mount point within the filesystem

auto - attempt to automatically detect the filesystem when mounting

ro - mount the filesystem as read-only
nodev - ignore/disregard any device files in the filesystem when mounted
nosuid - do not allow set-userid or set-groupid executables wthin the filesystem
noexec - do not allow execution of any file in the filesystem
umask=137 - when mounted, device owner has read/write permissions (execute is masked), device's group has read permission (write and execute are masked), and everybody else has no permissions (read, write, and execute are masked)

0 - filesystem does not need to be dumped

2 - the time when the filesystem should be fsck'ed on reboot (0=never, 1=primary;usually root partition only, 2+=every other partition)

Some of the settings are redundant, and the fsck order seems a bit odd in my opinion. You would mostly see 0 for removable media. You can find all of the info info above in man fstab and man mount.
