A slot can also be used to display a single message, such as a notification or error code. In addition, it can be used to display a live stream of data that is constantly updating. This data can be accessed by software programs to control the device. A slot can be configured to update data at different intervals, allowing it to support multiple applications simultaneously without affecting performance. This is called data scalability.
