Mostly correct. The compressor is directly attached to the high pressure turbine (HPT) via the high pressure shaft. The low pressure turbine (the 4 stages aft of the HPT), are directly connected forward to the high bypass fan through the center of the engine via the low pressure shaft. That is, the compressor and the HPT spins independent of the LPT and fan.

Reply to comment by Aviator506 in TIL that passenger jet engines produce most of their thrust from fan at the front, not from the jet exhaust, and that this is called a high-bypass engine. by Rilot
