A closed beta is a limited release where only those who have been given access can test the software while an open beta or public beta is a free (as in liberty) release that allows anyone to download and try it out.
The Incident Command System (ICS) is a systematic tool used for the command, control, and coordination of an emergency response. ICS allows agencies to work together using common terminology and operating procedures for controlling personnel, facilities, equipment, and communications at a single incident scene.
The Incident Command System (ICS) ICS was developed as a part of the FIRESCOPE program, (Firefighting Resources of California Organized for Potential Emergencies), during the 1970's, by an inter-agency working group representing local, state and federal fire services in California.
