I've been reading <advanced programming in the UNIX environment> 2nd edition and had a problem of understanding the following words:
I just don't understand why calling 'Linux' for the GNU/Linux operating system is not correct. This section also told me at the very beginning:
For example, Linux is the kernel used by the GNU operating system. Some people refer to
this as the GNU/Linux operating system, but it is more commonly referred to as simply
Linux. Although this usage may not be correct in a strict sense, it is understandable,
given the dual meaning of the phrase operating system. (It also has the advantage of
being more succinct.)
That is to say, in a strict sense an operating system is the kernel. So if Linux is the kernel used by the GNU operating system, why simply 'Linux' is not correct in a strict sense?
In a strict sense, an operating system can be defined as the software that controls the
hardware resources of the computer and provides an environment under which programs
can run. Generally, we call this software the kernel
Thanks in advance!
