Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I plugged in my external dvd-r (asus) via usb. It showed me some message on shell, that it has detected the cdrom(although its dvd rom as well but nevermind) and its of ASUS. But how do i know which dev it was associated with in /dev/ ?
Since i had to test something, i plugged it out, and save the output of
ls /dev/ > ~/result.txt
after plugging the dvd-rom, i compared the results and was able to find that it was associated with simple cdrom i.e. /dev/cdrom.
I wanted to know that is there any command that will tell me which /dev/ file was associated with external dvdrom ? i tried to see in the following result
1) df -h ( no results, just the already mounted partitions)
2) fdisk -l ( same as above)
3) dmesg | tail (shown almost the same result as was shown on shell at the time of plugging the dvd)
Are you sure scd0 isn't a symlink to sr0? In addition, you really should write udev rules to give your devices meaningful names, so that you always know what they're called. See, e.g. this about writing udev rules. The info there may be somewhat out of date, but it should get you started.
I just checked what you said. But scd0 is a regular file and not a symlink. But thanks alot for pointing me in directed of udev rules, i really need this sort of guidance.
Thanks alot to all you guys, let me tell you honestly. At first i thought linux to be a nightmare to learn, but when i see you generous guys(and girls) who are taking out time to help newbie like us, i just have one word to say
