How can I tell if my Raspberry Pi 2 is working?

The only way the Pi can impart diagnostic details is through the various LEDs it has on its board. Similar to the obscure BIOS beeps a big PC uses to wail its problems at you with potentially no working display. Each model of Pi sports its own array of LEDs.
