Parallel port is less faster than serial port because at a time 8 bit transmitted through 8 data bus and these data bus are then affected by magnetic effect because bits are form of voltage.

Serial port is less affected from magnetic effects.

The SCSI (Small Computer System Interface) port provides the fastest throughput among the options listed, particularly for high-end peripherals like early laser printers and storage devices.

SCSI uses a high-bandwidth interface and can manage multiple devices simultaneously, which allows for faster data transfer compared to the other options listed.
