    A kernel is the first layer of programming right above hardware. It tells the hardware how to function basically. Where as a ROM is the OS layer; It's like the wrapping paper for a gift. You don't have to flash the kernel, but flashing a kernel could improve battery life and performance on your phone as opposed to the stock kernel.
