Abstract: A method, system, and one or more computer-readable storage media for detecting sleeping computing devices are provided herein. The method includes querying, via a computing device, a system neighbor table of the computing device to determine whether a target computing device is reachable and, if the target computing device is unreachable, sending a neighbor discovery packet to the target computing device. The method also includes re-querying the system neighbor table to determine whether the target computing device is reachable and, if the target computing device is unreachable, determining whether the target computing device has been determined to be unreachable at least a specified number of times in a row. The method further includes determining that the target computing device is manageable if the target computing device has been determined to be unreachable at least the specified number of times in a row.

Abstract: The invention preferably is a teaching and learning method and system for improving the educational process of students by increasing the interaction between student and teacher preferably. The system preferably includes at least one teacher console, at least one communications server, at least one student console, and at least one database.

Abstract: Method and apparatus for collecting, processing and displaying audience-response data. Audience-response data is electronically collected then processed by a computer for storage and display with corresponding time markers. One or more time markers can be selected for display of corresponding audience-responses for the selected time maker. Accordingly, analysis of the responses can be readily made by the user of the system.
