System alerts are notifications generated by software or hardware to inform users about important events or issues. These alerts can indicate various situations, such as errors, warnings, or updates that require attention. They help users stay informed about the status of their systems and can prompt necessary actions to maintain functionality. Alerts can be configured to appear on screens, sent via email, or delivered through mobile applications. Common examples include alerts from antivirus software about potential threats, operating systems notifying users of updates, or network monitoring tools indicating connectivity problems. These notifications are essential for effective system management.
