Write the steps occur in sequence when you choose an option from a menu to execute a program If the program is in storage, the File Manager must calculate its exact location on the disk and pass this information to the Device Manager, which retrieves the program and sends it to the Memory Manager. The Processor Manager then sends an acknowledgment message to be displayed on the monitor so the user realizes the command has been sent. The Memory Manager then finds space for it and records its exact location in memory. Once the program is in memory, the Memory Manager must track its location in memory (even if it's moved) as well as its progress as it's executed by the Processor Manager. The Processor Manager must forward the finished message to the Device Manager, so that it can notify the user and refresh the screen. The Device Manager must receive the electrical impulses from the mouse or keyboard, form the command, and send the command to the User Interface, where the Processor Manager validates the command. When the program has finished executing, it must send a finished message to the Processor Manager so that the processor can be assigned to the next program waiting in line. When the Processor Manager receives the command, it determines whether the program must be retrieved from storage or is already in memory, and then notifies the appropriate manager
