Firmware updates generally are for correcting 'bugs' in the code that is used as the devices operating system. Sometimes the updates are to correct a functional problem and sometimes they are enhancements to existing functions that are working fine. Generally if the devices are working fine then you leave them alone, but if there is something critical like a security or compatibility flaw it is wise to update.
DASHBOARD (interface), a floating window that provides access to tools in a software program.
