I accept that UNIX is not fully safe, but it has fewer vulnerable compare to other. Every application requires the authorization by admin user. UNIX provides the UID and GID for getting to handle all permissions for all users, and files are controlled by users via these permissions.


UNIX OS is designed by implementing the C language so it has great portable operating system. That means this types of operating system can be used easily on any system like as PC or Mac. Today, C language is getting more popularity so mostly programmers prefer to work easily with this C language. User can also easily make communication along with hardware with helping of C language.


UNIX operating system is lightweight OS. So you have to need less resources to run it compare to other operating system. Mostly, UNIX distribution needed as little bit as 128 MB RAM along with similar amount for disk space.

Great Stability

UNIX operating system is great stable to other operating system, so UNIX doesn’t need to reboot the system to get maintain performance levels. It has less possibility to get hangs up or slow down.

No Require Anti-virus

As you already aware about that macOS, Linux, Ubuntu, Chrome OS and Android are designed by helping of UNIX operating system. So this operating system is preferred as protective from any virus, so as initially develop Chrome OS you don’t require to install any anti-virus.

Like as MS-DOS

If, you are getting more experience by using of MS-DOS in Windows then it becomes easily for user to implement UNIX OS, because their commands and user interface is mostly like as MS-DOS.

Multitasking Nature

UNIX operating system is a multitasking OS that means user are able to operate many program in UNIX operating system, as well as all programs run in parallel by using many types of multiprocessor.

Great Flexibility

Unix OS has most flexibility that means it can be used for many embedded systems sever applications, desktop applications, and so on. It also offers many restriction options for certain computer system. So users are only able to get install only mandatory components for the system.

Getting to Software Updates

In UNIX, users have control to get software updating, so you can easily to choose the needed updates. Here, enlarge number of system updates are presented. And these updates are more faster compare to other OS. So, you can easily to get system updates without getting any hassle.

Having Many Variants

Here, different kinds of UNIX OS variants are presented, If you are not getting to suitable by using UNIX then you can use other alternative as your convince like as Linux, Ubuntu, macOS or Redhat. Users are free to implement any types of UNIX operating system on their system.

Graphical User Interface

UNIX operating system is a command line operating system, but it also offers an interactive user interface that similar to Windows.

Easy to Find Expert

UNIX OS is more than 50 year old so you can easily to hire many developers who are available in the market. They can assist you to fix your issue related to your operating system. Today, UNIX developers are most demanded because many cloud based applications work on UNIX system. For example: mobile operating system such as iOS and Android and other online servers also designed by using UNIX OS.

Great Compatibility

UNIX OS is a better compatibility along with enlarge number of file formats, and it can support mostly all types of file formats.

Networking System

UNIX OS offers the most powerful support for computer networking system. The client server architecture can be easily designed to UNIS OS. It also offers many commands line tools like as mail, telnet, ssh, ip, and more for making connectivity along with the other systems and servers.

Installation Process

UNIX’s installation process is easiest to other operating system like as Windows, and it takes only fewer times. On installation process, UNIX needs few user input, and it doesn’t need much more system configuration even it can be easily installed on old system along with less configurations.

Modular Format

Unix OS’s utilities are developed in modular format. If you having good skill over programming language then you are easily able to construct small programs in modular form and then unite the modules and all modules will execute frequently throughout the system.

Fewest Code Execute

In GUI (graphical user interface) system, sometimes we have to require made many mouse click to get perform some certain  task, but in this phase of UNIX we can easily write on command in CLI and that task can be completed.


In UNIX, all kind of data is kept stored in the files, and working along with these files in OS becomes fastest and can be easily controlled by UNIX.
