Explain About What A Signal Is? |
|
Answer» A signal is a software mechanism that informs a process of the occurrence of asynchronous EVENTS. It does not EMPLOY priorities but it is more or LESS similar to a hardware interrupt. That is, all SIGNALS are treated equally. Signals that occur at the same time are presented to a process one at a time, with no PARTICULAR ordering.
