Exploring Operating Systems: From Kernel to User Space An operating system (OS) is more than a single program. It coordinates CPU time, memory, devices, and files. It provides a stable, friendly interface so applications can run without knowing the details of the hardware. The OS splits its work into two broad zones: kernel space and user space. The kernel handles core duties, while user-space programs run as separate, isolated processes. ...

Understanding Operating Systems: From Kernels to User Space An operating system (OS) is the software that lets apps run on your computer. It coordinates CPU time, memory, and devices so software can work together safely. The OS sits between programs and hardware, making complex tasks easier to manage. The kernel is the core part that talks directly to the hardware. Above it sits user space, where most programs run. Apps ask the kernel to do things through system calls, simple requests that the OS handles securely. ...
