Spectral location of individual OFDM symbols

The generic IFFT OFDM transmitter takes $N$ serial input data symbols, parallelizes them, maps them to their signal constellation points, and processes all $N$ resultant complex values using the IFFT to … Are these two different OFDM implementations, or is the IFFT implemented in a different way to achieve this? …

OFDM transmitter bandwidth

DAC output In order to transmit the OFDM signal on a carrier, more samples are required per IFFT output value. … How is OFDM typically implemented to ensure the correct bandwidth; should some subcarriers be set to zero? Should another DAC approach be used? …
