As we mentioned earlier, the system software is a piece of software intended to manage a computer's internal operations. It efficiently runs the computer's hardware and software. It serves as a link between the system and user interaction. However, the operating system facilitates communication with the computer's hardware and gives computer applications a place. It serves as a link between the user and the hardware. The operating system also runs continuously, whereas system software only runs when needed. Because of this, system software only accesses the main memory when necessary, as opposed to the operating system, which constantly uses it. While the operating system controls both the system and the system software, system software manages the system. Consequently, it is acceptable to conclude that all operating systems also function as system software.
