Learn the difference between UNIX and Linux

What is Unix?

Unix is ​​an open source operating system that is mainly used to run personal computers and Internet servers. Developed in the 1970’s at Bell Labs, this system was written in the C programming language.

What is Linux?


Linux is a set of free and open source software operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Meaning, Unix is ​​the kernel of the Linux operating system.

UNIX vs Linux
Now that we know these two operating systems, let’s look at the difference between Unix and Linux.

  1. Cost: Unix vs Linux

Which is more expensive or cheaper between UNIX and Linux? Linux is an open source operating system hence freely distributed. You can easily download a copy of Linux from the Internet or get it for free in books and magazines. However, you will need to pay for the server and Linux OS versions for large organizations.

On the other hand, UNIX is very expensive. However, there is no general pricing for the OS. Instead, the different versions of Unix have different prices. For example, Unix servers cost between $ 25,000 and $ 249,000.

  1. Security level: Unix vs Linux

Which OS is more secure? While both operating systems are vulnerable to different security threats, Linux is more secure than Unix. First, Linux uses the same characters as the Unix OS. This includes isolating tasks in a multi-tasking environment. In addition, passwords are encrypted in Linux and can be managed remotely.

As an open source operating system, users and developers can easily report errors in Linux. This does not happen in Unix as users have to wait for bug fixes to be developed. The process can be time consuming in an open source environment as issues are fixed within a short time.

  1. User base: Unix vs Linux

Who uses Unix and Linux? Linux is a normal operating system that can be used by anyone. Its user base constitutes regular computer users.

On the other hand, Unix can be used on both personal computers and Internet servers, but you need to have experience in this field.

  1. Usability

In terms of portability, Linux today is a very portable operating system that it can run from a USB device. On the other hand, Unix is ​​relatively rigid and therefore not portable.

  1. Source code

Given that Linux is an open source operating system, its source code is available to the general public. Anyone can see the source code used to operate the system. The source code for the Unix OS is not available to the public.

  1. Market share: Linux vs Unix

Market share can be interpreted as the number of people who use a particular operating system. Although Linux came many years after the Unix system, it has a bigger market share. The operating system has been installed in more than 25 million devices compared to Unix which has nearly 5.5 million installations.
