TBI,  Throttle Body Injection, the fuel injector(s) are located directly
above the throttle butterflies.
PFI, TPI, the injectors are located relatively close to the intake valves.

fit in with the above list?

On a v-8 TBI the alternating firing of the injector would be described as
bank, firing,  TPI/PFI, can be fired in banks, or batch firing (all at
once), or one injector firing per cylinder per ignition event (sequential).
