Linux - File system structure between different distros?

Q. I have been reading about Linux distros and I am lost in that kind of "flavors".
Would someone help me understand the main differences in the file system structure in Fedora and how this is compared with the file system structure in Debian?

A. From an end-user perspective there really isn't much difference. Mostly the file system structure (do you mean layout?) is the same. For example, standard programs live in one or more of /bin, /sbin, /usr/bin, /usr/sbin, and custom applications live in /usr/local/bin (but you don't need to worry about any of that, as the PATH variable manages finding them).

Debian-derived distributions provide for some configuration within the directory /etc/default/, and network interfaces are either configured in the file /etc/network/interfaces or by Network Manager.

RedHat-derived distributions (including Fedora) mostly use /etc/sysconfig/ for configuration files, and network interfaces are configured in separate files (one per interfaces) underneath /etc/sysconfig/interfaces/ or by Network Manager

Unless you're getting into writing portable installation scripts that's about as far as you really need to go.

How to Install Red Hat Linux Desktop version 4?
Q. I want to install Red Hat Linux Desktop version 4. Please tell me the step-by-step installation and which file system will be best for this O/S?
Like in windows, we have NTFS file system(which has very security features).
Is there any such file system in Linux?
Which file system should i use?

A. Put the CD in the drive, restart the computer and follow the directions. Take the defaults - they're the best choices for a beginner.

Do I need to defrag a big linux hard drive?
Q. I have a big hard drive (300GIGs) and wonder if I can do something to get better performance out of it. I run Ubuntu Linux. Is there something like de-fragmenting or optimizing the hard drive for linux? The file system is ext3.

A. If you are looking for extra speed I suggest backing up your data and upgrading to Ubuntu 9.04 which supports ext4.
