My understanding: some firmware, such as BIOS or router firmware, is stored in non-volatile memory, and once you 'flash' it in, it stays there. Think flash memory, like a USB stick or digital camera memory cards. Some firmware, such as that typically found on wireless cards, is just stored in regular volatile memory (like the main RAM on your computer), and must be loaded each time the device is activated.
