The computer users are wondering whether Linux and Unix are the same things? Are they compatible? Or Are they completely different?
Brief History of Linux and Unix:
Unix was invented before than Linux. In the late 1960s and early 1970s, two programmers invented Unix, at the beginning this system only could run one program at a time so it was named as Unics where U part is for uniplexed. After few years, AT&T license the source code for this new operating system and it started being used in various universities around the world and in early 80s AT&T had actually started to sell a commercial version of Unix that was named as System 5. After that its new version was also invented which is known as BSD (Berkeley Software Distribution). In the early 1990s, the university student wanted to overcome deficiencies that he saw in Unix and its several versions and write his own operating system and he did that and published it as a free operating system.
Linux and Unix Differences:
Linux and Unix both are multi-user operating systems. In windows or DOS, only one user can log on at a time but in Linux and Unix more than one user can log on at the same time. Linux is the kernel that used at the heart of the Android operating system, it runs on a wide range of devices including Desktops and Laptops, the user can also get it on the servers and it even runs on Raspberry Pi. As Unix came first and it is still widely used operating system but Linux is going in popularity because it is a free alternative to Unix in most instances. Unix is a commercially supported system, so it is more likely to be used by major companies whereas Linux is more often used by small firms and private individuals with freeware Linux servers. Linux Biggest advantage over Unix is the ability to pick and choose applications and servers.
The command, tools and major elements are same in Unix but on the other hand, Linux doesn’t have a standard set of tools, file systems or patches and there are even significant variations between different supported strands of Linux. Unix another advantage is that the vendors offer layers that make migrating to the next Unix version easier that is user can learn new Unix version while supporting an older one running through a layer like the new configuration. After all these advantages of Unix, why Linux is popular? The answer is Unix runs on just a few standard types of machines like Microsoft Office and in contrast, the user can tailor Linux to run anything from apps to OS to enterprise-wide servers.
There are plenty of people who are treated as Gods for being the Unix admins in a major company but Linux guys more often work at startups or for freeware projects and hope to get paid to support the code they write. At last, Unix wins a hand down for sheer economic opportunity.
