There are similarities and differences between the different operating system interfaces, the Mac OS, and Linux, the Unix, and the BSD, and the Windows 2000, XP, Vista, Windows 7, Windows 8, Windows 8.1 operating systems, and Windows 10 operating systems all have things in common with each other, the functionality of how the different operating systems can relate to one another, an Operating System controls the interaction between the components, memory, hard drives, keyboard, the CPU, a common platform for applications, the user interface.

There are also similarities between the different operating systems, like file management, how you add, delete, or rename files, toolbars, applications, application support, memory management, swap file management, Input and output support for printers, keyboards, hard drives, USB drives, the operating system also needs to utilise configuration and management tools.

The MAC OS easy to use, extremely compatible, relatively fewer security concerns, the disadvantages is that it has less industry support than Windows, and a higher cost of hardware and software, the different versions include:

Linux is a free Unix-compatible software system, and the many distribution versions (Ubuntu, Debian, Red hat/Fedora) the disadvantages to Linux are that there is limited driver support and limited support options.

Microsoft Windows a major market presence with many different versions Windows 2000, Windows XP, Windows Vista, Windows 7, Windows 8, Windows 8.1 and Windows 10 the advantages of Windows is that it has a large industry support, a wide variety of software support, but the disadvantages are that the large install base creates security risk, large hardware support can cause integration problems, the different versions include:

Windows 2000

Windows XP

Windows Vista

Windows 7

Windows 8

Windows 8.1

Windows 10

There are 32 bit versions of the operating system which run on 32 bit (x86) CPUs and 64 bit (x64) which run on 64 bit CPUs, the hardware drivers are also specific to the version as well.
