What is LINUX?
It is an operating system at the top. It acts as an interface between the user and the machine to perform specific task. The user performs some task in terms of input and this OS redirects the instruction to the machine in machine language. After performing the specific task it sends the computed task back to the user as an output. Well, all the operating system performs this task. Now, we shall study more about the LINUX operating system. LINUX means “GNU/LINUX” because LINUX is almost always used with the GNU tools.
LINUX is very similar to other operating systems like windows and OS X. There are certain measures that categories this operating system among others. It is widely used operating system apart from Windows. This operating system is run over various platforms from Pc’s to cellular phones. Even supercomputers runs on LINUX.
The important thing under consideration of the LINUX is that it is open source operating system. Open source simply means that its source code is available to all the users and it can be modified. No one individually owns LINUX. The competition to impart much to this software adds much to this operating system. About 1,000 developers across 100 different companies contribute to different kernels of this software. Initially it was made for server as an operating system. But this feature of open source has made LINUX to be used in any of the device in modern time. It do not include executable (.exe) files hence it is all free from viruses and hacking free software. This is the only reason that it is used in all of the major companies where security of database is highly important.
What is UNIX?
The UNIX dates back to 1969. Since then, it has changed a lot and various versions are out till today. It has built its versions for many platforms and different environments. It is the previous version of LINUX. The full form of UNIX is UNiplexed Information Computing System (UNICS), which was later termed as UNIX. This name has been given because the UNIX was first developed in 1970s; it required the data and addresses buses to be uniplexed. They were not multiplexed, hence it was named so.
What are the differences between LINUX and UNIX?
1. The developers of UNIX have a specific target audience and platform for their operating system. They have a clear idea what applications they have to optimize to give users the best results. Commercial UNIX vendors can do anything since they can maintain consistency between different versions of UNIX.
Whereas the development of GNU/LINUX, is more diverse as compared to UNIX. Here the developers come from different backgrounds and thus have different opinions and thinking. There are no specific tools and restrictions with the LINUX. The tools can be used on new editions without much testing.
2. Since the kernel is the most important part of any operating system. The source code is not freely available for any of the commercial version of UNIX. Whereas in the case of LINUX; it is freely available. Both the terms have a different compiling and patching kernels and drivers. With Linux and other open source operating systems, a patch can be released in source code form and end users can install it, or even verify and modify it if desired. These patches tend to be far less tested than patches from UNIX vendors. Since there is not a complete list of applications and environments that need to be tested on Linux, the Linux developers have to depend on the many eyes of end users and other developers to catch errors.
Henceforth we can say that both these operating systems works fine in their fields and due to the lack of (.exe) executable files it becomes virus less platform to work with. The security issues are less in terms of hacking the database. It’s open source code makes much difference for the development of the operating system in future and empowering it much times than before.

what is the full form of unix and linux
actually UNIX was called UNICS uniplexed information computing system then it changes 2 UNIX donno why...
LINUX is just a graphical user interface of UNIX created by Linus Torvalds therefore he combined the two 2 get
