Is there only one Linux kernel?
Yes, It is true, Ubuntu uses same kernel which was originally created by Linus Torvalds, but of course the updated version. The kernels of Linux Distributions are updated from the original one and See this link to get the view of kernel version changes.
Why are there so many distros of Linux?
Why are there so many Linux OS/distributions? Since the ‘Linux engine’ is free to use and modify, anyone can use it to build a vehicle on top of it. This is why Ubuntu, Debian, Fedora, SUSE, Manjaro and many other Linux-based operating systems (also called Linux distributions or Linux distros) exist.
Are there multiple Linux kernels?
Today, the GNU community has a kernel called “Hurd”. They then swapped the Linux kernel with the Hurd kernel to make “GNU/Hurd” systems. For instance, Arch exists as “GNU/Linux” and “GNU/Hurd”. Not only do various userland and kernel combinations exist, there are different Linux kernels.
How many Linux kernels are there?
Different Types of Kernels In general, most kernels fall into one of three types: monolithic, microkernel, and hybrid. Linux is a monolithic kernel while OS X (XNU) and Windows 7 use hybrid kernels. Let’s take a quick tour of the three categories so we can go into more detail later.
Is it legal to edit Linux kernel?
Yes. You can edit Linux Kernel because it is released under General Public License (GPL) and anyone can edit it. It comes under the category of free and open source software.

How many Linux distributions are there 2021?
Almost one thousand Linux distributions exist.

What is Linux Zen kernel?
Zen Kernel — Result of a collaborative effort of kernel hackers to provide the best Linux kernel possible for everyday systems. Some more details can be found on https://liquorix.net (which provides kernel binaries based on Zen for Debian).
Can we have more than one kernel?
It seems to me that you have answered your own question. There is no downside to having multiple kernels, as long as you know they work with your system, and it can occasionally be useful if you run into problems with a particular kernel for some reason.
Is Linux a OS or kernel?
Linux, in its nature, is not an operating system; it’s a Kernel. The Kernel is part of the operating system – And the most crucial. For it to be an OS, it is supplied with GNU software and other additions giving us the name GNU/Linux. Linus Torvalds made Linux open source in 1992, one year after it’s creation.
Is Linux free of virus?
Linux malware includes viruses, Trojans, worms and other types of malware that affect the Linux family of operating systems. Linux, Unix and other Unix-like computer operating systems are generally regarded as very well-protected against, but not immune to, computer viruses.
How does Fork() work in Linux?
Under Linux, fork () is implemented using copy-on-write pages, so the only penalty that it incurs is the time and memory required to duplicate the parent’s page tables, and to create a unique task structure for the child. The new process, referred to as the child, is an exact duplicate of the calling process (referred to as the parent).
Why is the Linux kernel now called GNU/Linux instead of Hurd?
Hurd still isn’t really production ready, whereas the Linux kernel has been for decades. That is why the Linux kernel is now use instead of Hurd and that the system is called GNU/Linux and not just GNU. There has been a debate about this at the time between Linux Torvalds and Andrew Tanenbaum: Tanenbaum–Torvalds debate – Wikipedia.
Which part of a Linux kernel has the least amount of software?
Thus this part (also called microkernel) will have the least software – to ease the effort of verification, and shift the less important parts to run at lower privilege. Overall, the software become much more complex – for microkernel – but it is also more secure, as the core part running at the highest system privilege is minimized.
What do you think about fork?
“fork ()” was a brilliant innovation that solved a whole class of problems with a single API. It was invented at a time when multiprocessing was NOT common (and preceded the kind of multiprocessing you and I use today by about twenty years). Take a look at spawn and friends.
