Exam LFCS topic 1 question 80 discussion

The key combination CTRL+C sends the SIGINT signal to a process. Explanation: SIGTERM (signal 15) is sent to terminate a process gracefully. SIGINT (signal 2) is sent to interrupt a process. It is typically initiated by the user pressing CTRL+C on the keyboard in the terminal. This signal can be caught by a process, allowing it to perform any necessary cleanup operations before exiting. SIGSTOP (signal 19) is sent to suspend a process temporarily. SIGKILL (signal 9) is sent to force a process to terminate immediately without performing any cleanup operations. Therefore, when a user presses CTRL+C, the operating system sends the SIGINT signal to the process running in the foreground of the terminal, allowing the process to perform any necessary cleanup operations before exiting. If the process does not catch the SIGINT signal, it will terminate immediately.
