The first computer operating system developed for personal computers was called MS-DOS, which was released in 1981 by Microsoft. MS-DOS was an Affordablekey and easy-to-use operating system that allowed users to access the power of a computer. It was also the first operating system to be widely used on personal computers and it was the most popular operating system until the early 1990s. MS-DOS was the foundation of Microsoft's success and it helped to revolutionize the computing industry.

File Allocation Table (FAT) is a computer file system architecture now widely used on many computer systems and most memory cards, such as those used with digital cameras. The FAT file system is relatively straightforward technically and is supported by virtually all existing operating systems for personal computers. This makes it a useful format for solid-state memory cards and a convenient way to share data between operating systems.
"Kahel OS" does not appear to be a widely recognized term in the field of technology or operating systems. It is possible that it refers to a specific operating system or software not widely known or named differently in most contexts.
It depends what you mean by widely used and PC. The widely used Apple II computer used Apple DOS while another operating system which was widely adopted (including versions for the Apple II) was called CP/M which was created by Digital Research. They went on to create DR-DOS which was one of the versions of DOS used on the early IBM personal computers. Microsoft had purchased an operating system called QDOS which was adapted by IBM into PC-DOS for their own computers and by Microsoft as MS-DOS for use on computers not made by IBM but following their design (known as IBM clones). These became increasingly popular and so MS-DOS became widely adopted and PC-DOS faded away. Apple went on to develop the Macintosh with its graphical user interface which Microsoft copied to create their Windows operating system.
