Let's look at Unix versus Linux and see what are
the differences. But before we get into finding
the differences, we'll find out what Unix is. Unix
was first developed for multi user and multitask
purposes in mid 1970s in Bell Labs by ATT, GE
and Massachusetts Institute of Technology, there
was an operating system but it was not allowing
for multi users or multitasking. So that was one
of the purpose for creating that. Then born Linux
in 1991, by a French student named Linus Torvalds.
Linux is mostly free and Linux is open source. So
what Linux free means is you could install the
Linux operating system in any of your computer
hardware. There are a few Linux distributions that
are not free like Red Hat, where you would have to
pay for support and subscription. And the open
source means that Linux code that was derived
from Unix is actually open to the public, to the
community, so they could go in and make changes to
that code and make the operating system the way
they want it to work in their own way. Unix is
mostly used by Sun and the operating system is
called Solaris. By the way Sun is now bought out
by Oracle. And also other operating systems that
are Unix is used as HP-UX by HP, AIX, and some other
distributions of Unix. Linux is used mostly by
developer communities or companies like Red Hat,
CentOS, Debian, Fedora, SUSE, Ubuntu and there are
so many of them even if you go out and search for
Linux distributions you will find so many of them.
Unix is comparatively supports very fewer file
system. Now what is a file system, that is
something that we will cover later, but there are
fewer file system that supported by Unix operating
system and a lot more file systems that are
supported in Linux flavors. Linux can be installed
on a variety of computer hardware ranging from
mobile phones, tablet, video games consoles, to
mainframe, and some supercomputers. It's just like
you cannot install Mac operating system on a Dell
machine. You have to install Mac operating system
on a Mac hardware. Just like that Unix is only
installed on certain hardware, whereas Linux, you
could install pretty much on every hardware that
is out there running AMD or Intel processor. So
these are the few basics about Unix and Linux,
and I hope you will find more information if
you're curious about it online.
