From DALL-E with some prompting
This diagram illustrates the process by which an application process requests services from the operating system through a system call. Applications running in user space cannot directly access hardware resources and must go through the operating system located in kernel space to perform necessary operations. System calls act as an interface between user space and kernel space, which is crucial for the system’s stability and security. The operating system abstracts hardware resources, facilitating easy access for applications.
