1. The process has completed its execution and has exited normally.
2. The process has encountered an error or exception that cannot be handled, causing it to terminate.
3. The process has violated system policies or security restrictions, leading to its termination.
4. The process has exceeded its allocated resources (such as memory or CPU usage limits) and is terminated to prevent system instability.
5. The user or administrator manually terminates the process using system tools or commands.
6. The system is shutting down or restarting, causing all running processes to be terminated.

1. Process Violation:
- Segmentation fault: Accessing a memory address outside the process's allocated address space.
- Page fault: Attempting to access a memory page that is not present in physical memory.
- Bus error: Attempting to access hardware devices in an invalid way.
- Floating-point exception: Performing an invalid floating-point operation.
2. System Resource Exhaustion:
- Memory shortage: Not enough physical or virtual memory available.
- CPU starvation: Process not allocated sufficient CPU time for execution.
- Other resource depletion: Resources such as file handles, sockets, or kernel objects are exhausted.
3. Signal Handling:
- System signals: The operating system sends signals to processes to notify them of events, such as:
- SIGTERM: Terminate the process normally.
- SIGKILL: Terminate the process immediately.
- User signals: Processes can send signals to other processes using the `kill` system call.
4. Process Deadlock:
- A situation where two or more processes are waiting for each other to release resources, leading to a permanent block.
- The operating system may terminate one or more of the deadlocked processes to break the deadlock.
5. Error Recovery:
- Core dump: When a process crashes, the operating system may create a "core dump" containing the process's memory state.
- The operating system may terminate the process and generate a core dump to help diagnose and debug the crash.
6. Resource Management:
- Priority starvation: The operating system may terminate low-priority processes to free up resources for higher-priority processes.
- Swapping: The operating system may terminate processes that have been swapped out of memory to recover that memory for other processes.
7. Security:
- Malicious code: The operating system may terminate processes that it detects as malicious or harmful.
- Privilege escalation: The operating system may terminate processes that attempt to gain unauthorized access to system resources.
- Segmentation fault: Accessing a memory address outside the process's allocated address space.
- Page fault: Attempting to access a memory page that is not present in physical memory.
- Bus error: Attempting to access hardware devices in an invalid way.
- Floating-point exception: Performing an invalid floating-point operation.
