On Linux systems there are some special paths like /etc/cron.d/, /etc/apt/sources.list.d/. That are the paths where you can place your own custom configs in separate files.
My question is — what does letter d mean?
directory :) Since there can possibly be a /etc/cron file as well. It is the same for /etc/modprobe.d/

Hard links cannot span physical devices. Exactly this statement I read while understanding the concept of hard link in Linux. Can anyone help me to understand this ?
A filename, is a pointer to an inode.
So if you're not on the same drive, it's impossible to link a file, because the inodes belongs to a specific disk

I've learned that linux directory is a file. So can I view it in binary mod like viewing other files with hexdump?
You can dump raw portions of a drive using the dd command and that is about as low level as you can get. You can also use debugfs to do maintenance on the filesystem.

I'm trying to make files in my linux virtual server browsable from my windows. I'm following the instructions given here: https://help.ubuntu.com/lts/serverguide/samba-fileserver.html
However, I cannot find the security parameter it's talking about. Can I just create that anywhere under the [global]? Or is there a pretty specific place to put it?
Yep, you can just specify the "security=" parameter anywhere in the global section.
