Draw a system context diagram for a programmable smart holiday music concert lighting system for an amphitheater. It includes a sound system, three spotlights and four rotating color changing lights. It also includes a device to establish its own IP address for the system so that the end user can access the system via the internet. It may also be accessed via wifi/bluetooth. The system should automatically come on about 30 minutes after sunset and should turn off after 5 hours if the system is still running. The system should be able to be manually turned on or off by the end user with a switch or via the internet/wifi. The system is connected to 110V using an electrical plug but may run off a generator for remote locations. The system should be able to play a predefined lighting pattern along with a song over the included speakers. PART B Design a diagram for the system with 4 input and 4 output functions

Both the JSP scriptlet and the JSP expression that are included inside a JSP file are run when the file is processed. If a local variable is declared in the scriptlet, it is still permissible to use that variable in a JSP expression as long as the variable is specified in the scriptlet. Consider it a given that the JSP expression will be placed just after the scriptlet in the order in which it was written. Is this accurate or does it not hold true?
