What do you mean polling of 8085?

Polling in the context of the 8085 microprocessor refers to the method of checking the status of an external device or peripheral by the CPU at regular intervals. Instead of waiting for an interrupt signal from the device, the CPU actively queries the device to determine if it requires attention or has data to send. This method can lead to inefficient CPU usage, as it consumes processor cycles while checking devices that may not need servicing. Polling is often contrasted with interrupt-driven I/O, where the device signals the CPU when it needs to communicate.
