Without an operating system, the user and system cannot interact.

We mainly have three kinds of operating systems namely, Linux, MAC, and Windows.

To begin with, MAC is an OS that focuses on the graphical user interface and was developed by Apple, Inc for their Macintosh systems.

Microsoft developed the Windows operating system.

It was developed so as to overcome the limitation of the MS-DOS operating system.

Windows User Full Memory Protection

Linux is UNIX like a source software and can use an operating system which provides full memory protection and multi-tasking operations.

Windows is dominant over the other two as 90 of users prefer Windows.

Linux is the least used operating system with users accounting for 1.

MAC is popular and has an overall user base of 7 over the world.

MAC is costlier than Windows and the user is forced to buy a MAC system built by Apple.

It was supposed to be a graphical user interface on top of MS-DOS.

All features of MS-DOS were later integrated with Windows 95 release.

It began as a graphical user interface right from its inception.

In 2005 the design and structure of MAC OS were changed to Intel x86 based architecture.

It is open to consumers and everyone can use as per their specifications.

Some common folders like documents, pictures, music, videos, and downloads.

All these files can be stored in these folders and also new folders can be created.

It also has files which can be a spreadsheet or an application program.

If you go to dig into your MACs hard disk through finder you will see many directories.

The root directory of MAC may encounter when they visit their own MAC book.

You can explore the file system and directory structure by going to directories like Application, Developer, sbin, tmp, etc.

There is a single file tree and all your drives are mounted over this tree.

It is responsible to store all user information with its passwords and device relate information.

Windows User Drivers If Necessary

The registry also has an editor which allows you to view all keys and values or even drivers if necessary.

All application setting is stored on program basis under the different users in the same hierarchy format of the files being stored.
