What exactly do we mean when we say I am using Linux?
I was going through an article on GNU which goes something like below:
There really is a Linux, and these people are using it, but it is just a
part of the system they use. Linux is the kernel: the program in the
system that allocates the machine's resources to the other programs that
you run. The kernel is an essential part of an operating system, but
useless by itself; it can only function in the context of a complete
operating system. Linux is normally used in combination with the GNU
operating system: the whole system is basically GNU with Linux added, or
GNU/Linux. All the so-called "Linux" distributions are really
distributions of GNU/Linux.
I always thought Linux as a kernel + OS but looks like Linux (terminology)
= Linux kernel + GNU OS. Could someone point out the exact functionality
of each in the "Linux" terminology we use in our day-to-day life. Also
according to wiki GNU's design is Unix-like but differs from Unix by being
free software and containing no Unix code. I thought Unix is open source.
Isn't it?
