Linux and UNIX based operating systems have gained a lot of popularity in the recent years. While Linux operating system is available under general public license and is available freely, the UNIX is the same as that of Linux but it is copyrighted name that only big companies can use. It has almost the same features as that of the Linux operating system and also shares the same advantages with it. The Linux kernel that first came up as a project work of a student in the early 1990’s has now become a worldwide success. The Linux kernel can be modified as and when required and all you need to know for this is any of the programming languages such as c, python etc.
The major advantages of Linux or UNIX over the other operating systems are the following
Stability
Linux or UNIX operating systems are much more stable than the others. Even if an application in Linux crashes which is itself very rare, then generally no harm is done to the kernel itself and the problem can be solved just by re installing that particular application.
Free software

Runs on old hardware
Linux can run on any machine and it has minimum hardware requirements. It can run even on the old 386 or 486 machines because of its minimum RAM requirements.
Security
Till date no virus threats have been reported that has affected the Linux or the UNIX kernel. There is no need of installing any antivirus programs and still remain protected while you use Linux or UNIX.
