Yes, the Linux Kernel is preemptive, as are effectively all modern operating systems.

A non-preemptive multitasking operating system essentially requires the cooperation of the programs to tell it to switch to the next program. This means that a single application can hang the entire computer.

A preemptive multitasking system will interrupt the programs and switch to the next program waiting to run, without requiring the programs to tell it that they are done.

Thanks kandra.

your extra information (a single application can hang the entire computer) has instructed me to understand that which kind of OS is non-preemptive.
