13. Processes A process is program code that is in some state of execution. It has own address space, some or all of which are mapped by the OS into main memory. It has a single Thread or Flow of control.

14. Processor Single processor machine –Multitasking –MultiThreading –Concurrent Programming Multi-processor machine –Parallel Programming

15. Threads class A extends Thread { public void run() {...} } Class A implements Runnable { public void run() {...} } Main program: A a = new A(); a.start();

16. Thread methods To stop a thread: –Interrupt() To block a thread: –sleep(millisecond) –wait() –join()
