Process Scheduling

• Multitasking operating systems come in two flavors: cooperative multitasking and preemptive multitasking
• preemptive multitasking
• The act of involuntarily suspending a running process is called preemption.
• Linux, like all Unix variants and most modern operating systems, provides preemptive multitasking.
• The time a process runs before it is preempted is predetermined, and it is called the timeslice of the process.

• cooperative multitasking
• The process does not stop running until it voluntary decides to do so.
• The act of a process voluntarily suspending itself is called yielding.

• I/O-Bound Versus Processor-Bound Processes
• runqueues
