What is the linux kernel and differences to userspace

The Linux kernel is the heart of the Linux operating system. It is the low-level software that controls the communication between the computer’s hardware and the software that runs on top of it. The kernel is responsible for managing the system’s resources, such as memory, processors, and storage devices, and providing a stable and secure environment for other software to run on. One of the main differences between the Linux kernel and user space is that the kernel runs in what is known as privileged mode, while user space runs in unprivileged mode.
