Is this a serious question?
Linux is an open source operating system with numerous distro's available. Most of the world's supercomputers run on Linux as do many enterprise class companies use Linux for their servers.
I use Linux at work for my desktop PC and I like it far better than Windows.
That's definitely not the case for web servers.Yes. Most companies use Windows I bet for their servers.
Right. CentOS is a pretty popular one for web servers as well as Debian.That's definitely not the case for web servers.

Software development is another area where Linux is widely used. Ever wonder what the software engineers who write all those web apps and web servers you encounter on a daily basis use to do their job? It's almost always Linux or a Mac. I don't think I've ever met a web frontend or backend developer who prefers Windows although I'm sure they exist. As for why do some prefer Linux to using a Mac? The answer is very similar to why lots of people prefer Android phones to iPhones (e.g. Macs are expensive, some just don't like Apple, Linux allows for more customization, etc).
Lots of big data centers also use Linux. I wouldn't be surprised if Apple even uses Linux, instead of MacOS, for some of their data centers.
Linux is all over the place. It's pretty much what the internet runs on.
Even the Android OS by Google is built on a modified Linux kernel. That's kind of a popular system, too.
Facebook and Twitter both use Linux, and both contribute to open source projects themselves. I wasn't able to find what particular distributions they each use with a quick search, but I'm assuming they're both probably a custom build tailored more to their specific needs. There is likely some blend of operating systems across their networks, especially if you're wanting to include networking equipment in that count.Does FB and twitter use Liniux for their websites? It appears I am ignorant of Liniux usage as I was only looking at consumer and business usage in which I only see Windows or Mac.

What is IOS built on?
iOS was built on the kernel of OS X, which was also built from FreeBSD.What is IOS built on?

iOS (and macOS, tvOS, etc.) is built on Darwin, which is based on FreeBSD, as I mentioned in my post above. (Unless it's Cisco IOS, which is completely proprietary.)
The classic Macintosh operating systems were completely made by Apple.I see thanks

Interesting thanks. What was the old (pre OSX) Mac kernal built on? You know the OS that used to crash allot and was referred to as OS 7.x-OS 9.x?
Technically, MSDOS 6.22 was the last version which ended 18 years ago, in 2000, with Windows Millennium.until Windows 98 which was the end of MS DOS.
Sort of. PowerPC and 68K were processors, Apple II was a computer, and ProDOS was an operating system. AppleDOS, ProDOS, and SOS were all operating systems developed by Apple around that time.I see. So I guess before Power PC and 68K we had the Apple II which was based on proDOS (?)? I ask because thats when I first started using Apple products was during the Apple II days and as I recall those apps would not run on a 68K Mac my first being the LC III without a compatibility card which shipped with some Macs before the LC III.
But during those days before Windows 3.11 we had MS DOS and Windows has for many years been able to run MS DOS apps until Windows 98 which was the end of MS DOS.

The switch in processor architecture between the two machines is likely the main reason that software didn't work on the newer computer, probably along with the operating system and other hardware differences.
Indeed, compatibility across various platforms (even within the same brand) could be a pretty complex issue back then, and a lot of great software has become extremely difficult to find and run as a result, along with various advancements and changes to computing since. Lack of archival of software and its source code is also another huge factor in software being lost in time.I am glad we are out of those days except that I miss some old games and apps from the Mac 68K os 7.x days that have seen no OSX replacement.
Lunatic Fringe from After Dark
Prince of Persia
Many other games
Where in the world is Carmen Sandiego?
Oregon Trail
Redshift
The animals and many others that I used to play in school.

Even if you have the software, it can be quite the challenge to get it working through emulation of those old systems. At least some of those classic PC games like Prince of Persia and Oregon Trail have survived in some way since then.
