hi,
Can anybody tell me please what is the major diiferences
Between unix and Linux kernel.

'UNIX' is just a brand name owned by a group called 'the Open Group.' There is no one UNIX kernel; any operating system which meets the Open Group's 'Single UNIX Specification' (and pays lots of money) can call itself UNIX.

Solaris, HP/UX, and even MacOS are all UNIX, and they all have completely different kernels.

Linux is the offshoot of a project originally started by Linus Torvalds in his dorm-room. He created a kernel that was "mostly based on Unix ideas," but tossed in a few ... well, more than a few ... ideas of his own. And then, lots and lots of other people have followed in those footsteps.

Unix, in many ways, did the same thing about twenty-five years earlier. But it was a project of Bell Labs, which was at that time a government monopoly. So it had a different provenance; a different path to getting to where it is today.

The two systems by-and-large share many more common features than fundamental differences. That's very important, because "Unix/Linux" is rapidly becoming a lingua franca for software development. Whereas Microsoft Windows basically runs on one type of hardware, software that is targeted for Unix/Linux runs on several dozen. It's a trend that will surely continue.

This statement is incorrect and has already been discussed. On the opposite, it was a private monopoly and the US government broke it in pieces.

I came across both of these posts, that said that Bell Labs was a government monopoly, and was wondering where this idea came from.
