A disk operating system is usually abbreviated as DOS. It refers to operating system software but can refer to the entire operating system. One type is the Commodore that was on ROM chips in the disk drives while others were stored on a disk that had to be loaded for use. Others include MS-DOS and PC DOS from Microsoft.
The data required by the operating system (passwords, access controls, accounting information, and so on) would have to be stored in or passed through unprotected memory and thus be accessible to unauthorized users. Akmal Waheed waheed007@gmail.com

Hard-drives are not memory as such, they are storage devices. However, the contents of RAM (Random Access Memory) are stored on the hard drive in the form of one or more paging files, allowing the operating system to realise more RAM than physically exists (virtual memory). The contents of RAM are also stored on the hard drive when the computer enters hibernation mode. Aside from that, hard-drives provide long-term storage of programs and files that can be loaded into memory as and when required.
