What is Firmware for a mp3 player?
“Firmware” is the name of the type of software that is loaded into the “permanent” memory of your MP3 player that is used to run the player, provide the user interface, and support the different music file types. Think of it as an operating system like Windows or MacOS only much lighterweight. To play new music file types, add new functionality (such as PlaysForSure), or fix operational problems, you must download a “firmware upgrade” from the manufacturer and install it on your MP3 player.
