In modern healthcare environments, the continuous operation of medical equipment is not just a matter of convenience—it is a matter of life and death. From imaging machines and patient
An uninterruptible process is a process which happens to be in a system call (kernel function) that cannot be interrupted by a signal. To understand what that means, you need to understand
A process performing I/O will be put in D state (uninterruptable sleep), which frees the CPU until there is a hardware interrupt which tells the CPU to return to executing the
