According to Tutorialspoint

“An operating system is a program that acts as an interface between the user and the computer hardware and controls the execution of all kinds of programs.”

Operating System is connecting link between users and computer resources. We can share, edit , work on any files through Operating System (OS). It provides user interface to perform all tasks.

Over the time Operating System (OS) gradually developed with a lots of features.Depends upon features and developing company,We  have Linux, Unix,Mac and Windows Operating System (OS).

Let us see each Operating System (OS) one by one :-

  • Linux can run on “regular” off-the-shelf computers.
  • Linux has hundreds of different distributions or flavors.
  • Linux are free to use.
  • Linux is used widely.


  • UNIX-based systems generally require proprietary hardware configurations.
  • Variants are much smaller in number
  • UNIX applications generally cost money.
  • Users are less in number.

Mac OS

According to Wikipedia :

macOS is a Unix operating system developed and marketed by Apple Inc. since 2001. It is the primary operating system for Apple’s Mac computers. Within the market of desktop and laptop computers it is the second most widely used desktop OS.

Windows OS Features

Windows OS is number one OS used world wide. It is most popular used OS due many features.Lets see the features of Windows OS :-

  • Easy to Use
  • Less Costly than macOS
  • Multitasking
  • Compatibility
  • Easy and clean user interface
  • Widely available applications
  • Huge community support.


Operating System are the linking between user and hardware resources.Though there are many OS available, Windows is most popular among all.To find difference between Linux, Unix, Mac and Windows, we have to check all one by one.Each OS have their own functions,features and usability.

Difference between Linux vs Unix, mac vs Windows,Unix vs Windows ,mac vs Linux and Linux vs Windows are all given above with separate headings. OS ranges from free to paid .
