Difference: System SoftwareSystem software is responsible for managing various independent pieces of hardware in a computer system so that they can work in harmony. System software enables computer users and other software to treat the computer as a whole, regardless of how each piece of underlying hardware works.
Generally speaking, system software consists of an operating system and a set of basic tools (such as compilers, database management, memory formatting, file system management, user authentication, driver management, network connectivity, etc.).
Application softwareApplication software is software that has been developed for a specific purpose. It can be a specific program, such as an image browser. It can also be a collection of programs that are closely related to each other and can work together, such as Microsoft's office software.
It can also be a large software system consisting of many independent programs, such as a database management system. The more common ones are word processing software, such as WPS, Word, etc., information management software, aided design software, such as AutoCAD real-time control software, education and entertainment software, etc.

An operating system is software that runs on hardware, whereas application software is software that runs on top of an operating system. For example, if you think of the hardware as the foundation, the operating system is the first floor. The software is the second floor.
Think about it, if you don't have a first floor, can you build a higher floor?

The operating system is a special software that is used to build the user with.
The DAO of the computer is a bridge for communication and use between the user and the hardware inside the answering machine. Without the operating system, we will not be able to use the computer properly. System software is software that is installed on the operating system for the convenience of users, and there can be many classifications according to different functions and applications, and application software is software that runs based on the operating system.

I think you're misunderstanding that applications run on top of the operating system, and that's true.
The operating system provides a number of APIs (which can also be called"System calls"For program developers, the functions of these APIs are very basic, such as file cutting and copying, network communication, screen drawing, etc., which are indirectly dealing with hardware (external memory, network card, graphics card), you can't write a network communication software directly in C++ without using the socket socket API provided by the operating system.
In addition, the program is converted into a process and runs on the machine, which is also responsible for the operating system (process management), so the final encoded structure of the generated executable file is definitely different from Windows and Linux, depending on what platform you are on and which compiler you use.
