In functional analysis, a reproducing kernel Hilbert space (RKHS) is a Hilbert space of functions in which point evaluation is a continuous linear functional...

The Linux kernel is a free and open source Unix-like kernel that is used in many computer systems worldwide. The kernel was created by Linus Torvalds...

services in a hybrid kernel are still in kernel space. There are none of the reliability benefits of having services in user space, as with a microkernel...

only a single address space, there is no need for repeated privilege transitions to move data between user space and kernel space. Therefore, a library...

outside kernel space. For example, many Unix operating systems panic if the init process, which runs in user space, terminates. The Unix kernel maintains...

The Linux kernel provides multiple interfaces to user-space and kernel-mode code. The interfaces can be classified as either application programming interface...

Implementing system calls requires a transfer of control from user space to kernel space, which involves some sort of architecture-specific feature. A...
