Hi Ryan

Bootloader can be seen as a process which helps burn the code into a microcontroller. It can be an external or an internal process; sometimes you use a microcontroller based thing to burn a hex file into another controller, in this case the former becomes bootloader. While at times you directly burn code into the main controller itself, things like BootloadHID perform such tasks.

Hope this was helpful

bootloader is a small piece of program written into internal FLASH of micro controller and it occupies small space in internal ROM. it allows programming of rest of the FLASH through serial comminication (Tx and Rx)

means the program can be loaded into reamining internal flash of micro controller from PC/laptop through serial port (USB)
