So in another words the proper term is "root" or "unroot" because the OS is "kernel." #ComeAtMeAppleSheep

I'm so surprised that a large group of smartphones run the EXACT same system as desktop Linux PCs!

I hate the way u speak. Every two seconds I have to adjust the volume for a second and then readjust it again in order to not get jumpscared each time.

To be fair. Android is not really a multitasking OS in the traditional sense.

Watching this video i came to know that the windows is using the ANTI Kernel (before this i thought that Microsoft uses a custom built kernel), my doubts are cleared now & its a good thing, i wanted to know how these operating system thing works, which i might have to go even deeper to learn. Thanks for the provided information Gary, its really greatly appreciated. :)

Glad to finally see someone who actually qualifies to speak on a tech channel. All these channels and ridiculous article sites are full of people who think they're "techie" but have no authority to speak on any subject.

You do not need to have root access in order to install a custom kernel.

oems stack the the kernal with a bunch of useless things and addware which is the main reason custom ROMs are so much better

Linux kernal is really optimized, and is continually worked on by the community. Win!

The kernel of macOS (formerly OS X) is called XNU. Darwin is the open-source version of the actual operating system as a whole

Mac OS uses the XNU Kernel. Darwin is an OS.

is kernal a software?
Aleksa Gordic (8 months ago)
As far as I know kernel is not the lowest piece of software on every OS, it is so in Linux. On other operating systems like Windows or some real time operating systems like FreeRTOS you have device drivers/HAL (hardware abstraction layer) that are not part of the kernel nor a part of OS. So the OS has certain APIs to certain hardware modules and then it is the task of driver developers to create drivers that actually implement those function calls from OS API. Maybe I'm wrong, if so feel free to correct me.

Darwin isn't a kernel; Darwin is an open-source operating system that includes the kernel used in macOS and iOS, the XNU kernel.

when we put our phones on sleep, what if that time process decreases and our battery life increases and we use our phone that time our process increase according to our needs isn't it by this method we get bhot the things battery life as well as processors speed at same time

So Kernel is not related to Linux history? It's related to any OS ?

Thumbs up if you are a Kernel Junky 😁👍 like me and always flashing custom kernels to your devices
"Underneath the bonnet" — I'm glad this expression translates directly across the pond.
Matyáš Cmbulka (1 year ago)
Just a quick note. Kernel doesn't talk directly to the hardware. It would be impossible for it to do so as every CPU might have different instruction set and so on. That's why hardware manufacturers include firmware with their products. On personal computers this firmware is called BIOS (Basic Input/Output System) or UEFI (Unified Extensible Firmware Interface) which sits between hardware and kernel.
