Understanding Operating Systems: From Kernel to User Space An operating system (OS) is the software that keeps your computer usable. It sits between your programs and the hardware, coordinating tasks, memory, and input/output. Think of it as the conductor of a busy orchestra. The kernel is the core of the OS. It runs in a privileged mode and talks directly to the processor and devices. The kernel makes decisions about who runs, when, and how much memory is allowed. It handles critical duties like starting programs, talking to disks, and keeping devices working together. ...

Demystifying Operating Systems: From Kernels to User Space An operating system (OS) is the software layer that connects your computer’s hardware to the apps you use every day. It manages memory, time, and input/output so programs run smoothly. In most OSs, the code lives in two large zones: kernel space and user space. Kernel space is the trusted core that talks directly to the computer. User space holds everyday programs, libraries, and the tools you interact with. ...
