Linux is an open source operating system whereas Windows OS is commercial. Linux has access to source code and alters the code as per user need whereas Windows does not have access to the source code. In Linux, the user has access to the source code of the kernel and alter the code according to his need.
The first computers did not have modern storage devices such as hard drives, optical drives, or flash storage. The first storage methods used punch cards, paper tape, magnetic tape, and even audio cassettes.
Floppy disk and hard disk storage require software to read from, write to, and manage the data that they store. The Disk Operating System (DOS) is an operating system that the computer uses to enable these data storage devices to read and write files. DOS provides a file system which organizes the files in a specific way on the disk. Microsoft bought DOS and developed MS-DOS.
