hi all , i want useful link so i can understand F15 operating system working like , interrupts, networking, kernel , I/O , Memory management , and some like that ..
thanks

Try http://www.google.com for a start. What you're asking for is scattered in a LOT of places, and you can look all that up yourself. You can also try kernel.org for descriptions/source-code, but you don't say what level of information you're looking for.

And be aware that Fedora 15 is OLD...the latest is 19, so learning something that's already 4 versions behind doesn't make much sense.

to backup what tbone stated, the older Fedora used sysV, now with Fedora 19 they have moved fully to systemd. a much better way of controlling how processes start, stop, run, load, etc...

Also dont forget to look at the fedora release notes and their kernel notes about their daily/weekly builds for both F19 and F20, should be in public beta soon if its not already there.

These links may prove as useful-

The new Fedora 20's code name is "Heisenbug" and the schedule is here:
http://fedoraproject.org/wiki/Releases/20/Schedule

It's entirely up to you; AbidDhanaiser but you may want to consider using the more stable version of
Fedora 19- If anything you will have stability which is a good thing-

i second that, learning how fedora 15 works would make a halfway decent academic exercise, but outside that, fedora 15 is 4, soon to be 5 generations out of date, so learning it inside out would have little to no practical value.

Actually , i need to know how FEDORA operating system handle interrupts , what are I/O in Fedora, memory management , process execution , all those topic which are necessary to understand OS working .
I did much search from Google , but it only told about its documentation , server config , GUI , but not proper OS presentation .

i am searching from last two days not getting exact presentation to present FEDORA operating system working. i need it

just HOW things are being done is changing
" those times they are a changing "

fedora19 and OpenSUSE12.3 have already made the full move over to System D from the OLD System V
RHEL6 /CentOS6 are still in a change over mode , RHEL7 will be systemD

so
using the OLD system v "init" system
or the new systemD

so the old way of doing things from fedora 15 ,RHEL5, Debian stable
or the new OS's and what future OS's will use

-- something bell might have said ---
there is this "new fanged" thing called " the telephone" , it's going to change the world ......


--- edit ---
have a look at " udev " and how the linux KERNEL works

Hi,

You could do some digging(search) here at LQ for potential links or solutions to your inquiries with Fedora 15.

I too agree that to learn the workings of older releases like Fedora 15 will only help you with Fedora 15 since the changes that have been made with new releases of Fedora.

As to the inner workings of the Kernel, look at the archives at Kernel.org or KernelNewbies.org.

Links I like to provide to users with inquiries of your type;
Hope this helps.
