things look reasonable when other people read the.

I am need to present a brief presentation to my Operating Systems class involving various components of the OS. I have spent the past few days researching the web including multiple Fedora project websites and online databases and found nothing. If anyone is able to give me some simple answers or even relevant information or sources would be wonderful.

You should look at the linux kernel for that information. Fedora uses pretty
up to date kernels in case that matters as the scheduler changes from
time to time.

That's app specific.

> -Techniques for Shared Memory
What are you looking for here? Shared libraries, process communication,
something else. There are a few things (e.g. postgres) that used shared
memory for process communication. Shared executable code for libraries
is the default.

This is app specific. In the kernel things are moving toward using RCU.

This is app specific.

> -What languages was used to design the OS 
Linux (the kernel) is mostly writen in c with some assembler. It uses some
gcc extensions that are not supported by all c compliers. If by OS you
mean the software environment provided, than lots of different languages
are used.

It depends on the app. Posix is one set of apis.

> -Implementation structure (modular, layered...)
This is app specific. The kernel has modules but is not really modular.

It sounds like you might really be more interested in the linux kernel and
reading up on that may be more helpful to you.
