What is inod ? what responsibility does the OS have?
and what are the three main components of the os, the core, the shell and?

would appreciate some help i have som homework i need help with

Nobody here is going to do your homework for you. Have you looked in you textbook/lecture notes? Google will return a lot.

One thing I will say is that there's no clear-cut answer to what the responsibility of the operating systems are. In the Unix world, the OS is responsible for relatively little -- things like the shell and windowing systems all work in user space. In Windows, the GUI shell is part of the OS proper, as I understand it. Do you consider system programs like the shell part of the OS or not? There are some interesting questions to chew on here, and you're going to need to do some thinking on your own.

Hi Alexander!

Didn't your teacher give you a book to read about all this stuff.

Nice try?

Martin

No he didnt, this is a course after college, we buy our own books and iv bought one.
a unix beginners guide, but it doesnt say these specific questions and my teacher said that i should ask on the net
if i couldnt find it. i guess i tried.

Here is a rather technical description of what an i-node is:

Is this the right level of detail for you?

Martin
