What is who (unix, linux, ubuntu, debian, kali)?

Question

Operating Systems

What is unix, ubuntu, linux, kali, debian?
Like unix is ​​the origin of everything, linux is an OS from unix like ones, ubuntu is an OS built on the basis of debian gnu / linux, debian is supposedly also an OS and Kali too?
What about distributions then?
In general, someone who understands well explain

Answer 1

Any operating system consists of two parts - the kernel and the environment.
The kernel, of course, is system calls, working with equipment and processes.
The environment is what the user interacts with, a set of utilities, programs, and the startup system.
As you might guess, different environments can be attached to different cores. The composition of the kernel and environment sets the distribution kit - a set of kernel and environment.
So, UNIX versions differ precisely in these sets, there are distributions of classical Unix systems, such as BSD (openbsd, freebsd, solaris ...). There are Linux distributions that differ mainly in their environment, but share the same linux kernel.
Now let's talk about the environment. The composition of almost every environment includes such a thing as a package manager. Through which the installation and deployment of the Environment itself takes place. It is by the type of package managers that linux distributions usually differ. There are debian-like similar distributions (dpkg), there are redhat-like ones (rpm), there are alternative ones (pacman, yast, make world).
In general, all Linuxes include the linux kernel + some of the package managers + a launch system like init / systemd / upstart + a set of programs to choose from the founders of the distribution
All Unixes have one of the unix kernels + everything else is the same, but its own!
Well, the whole history of Unix is ​​beautifully described in https://ru.wikipedia.org/wiki/UNIX

Answer 2

What is unix, ubuntu, linux, kali, debian?

in short:
ubuntu, debian, kali are UNIX-like operating systems (distributions) based on the linux kernel .
A UNIX-like system is a system that adheres to most of the principles of unix , such as everything is a file.
unix is ​​an operating system developed in the late 1960s by Bell Labs employees, primarily Ken Thompson, Dennis Ritchie, and Douglas McIlroy.

Answer 4

UNIX is a type of operating system and also a trademark (owned by The Open Group). A term that unites all UNIX-like operating systems - thousands of them, even M$ was noted in this field ...
Linux is one of the UNIX-like OS subtypes. In fact, Linux is also a trademark, owned by Linus Torvalds and actually it is only a kernel, so the word Linux is as impersonal as the word Car and is usually used in the context of a specific
ubuntu distribution - a Linux distribution. The main idea is friendliness. You have to pay for friendliness and unfortunately, most of those who ask not too smart questions have the #ubuntu
debian tag - a Linux distribution that, according to its adherents, is suitable for both beginners and masters :)
kali is a specialized Linux distribution for security people. (Kali - in the Hindu pantheon - the goddess of death)
