Study Notes

Interrupts can occur during a process
Interrupts can be handled without changing the current process state
PCB information is restored during interrupts
Process state change from Running to Ready or Blocked is complex
Current processor state must be saved during state change
PCB information for the current process must be updated during state change
Relevant information, such as the cause of termination, can be stored during state change
State change involves additional operations
Interrupts can occur during state change operations
Interrupt handling can be done without changing state during state change operations.
Process scheduling is the mechanism used by operating systems to manage the execution of processes.
The scheduler selects the next process to be executed from the ready queue.
The scheduler must also handle the blocking of processes, caused by I/O or other events.
A process has a process control block (PCB) that contains information about the process and its state.
The state of a process can be running, ready, blocked or terminated.
Modern operating systems allow for the execution of multiple threads simultaneously.
A process has two characteristics: property of resources and planning and execution.
The unit that is activated is called a thread or lightweight process.
The unit of property of resources is called a process or task.
The scheduler must update the PCB of the selected process and restore the processor state to start or resume execution.
