Preemptive multitasking operating systems allow the system to deal with important external events rapidly, for instance like incoming data, moreover, these events may require the immediate attention of one or another of the processes to function. This regular amount is referred to as a “slice” of operating time. Preemptive multitasking allows the computer system to more reliably allow each process running on the operating system to get a regular amount of operating time. Preemptive operating systems are a core feature of all Unix-like operating systems, ranging from Solaris, Linux, as well as the modern versions of Windows.
Preemptive systems date back to the 1960s where they were first implemented, it up until 1969 when they were available in some operating systems for computers. Types of Multitask Operating Systems Preemptive Multitasking
