System sounds are audio cues generated by a computer or electronic device to provide feedback or notifications to the user. These sounds can indicate various events, such as alerts for incoming messages, errors, or the completion of tasks. Common examples include the sound of a notification when a new email arrives or the chime that signals the successful completion of a file download. These sounds are an essential part of the user experience, helping to enhance interaction with the device. They can be customized in many operating systems, such as Windows or macOS, allowing users to choose sounds that suit their preferences or needs.
