RS-232 serial ports are far slower than USB ports. With very few exceptions, devices that use USB ports would be impractical to use on a serial port.
These interface products turn regular USB ports into ports for serial products that can be connected to other serial components for communication uses.
serial ports are not in use any more, the new standard is usb

if the Dell computer has USB ports, then all you would need is the USB-iPod cable and download/install iTunes. If you system is really old and only have serial ports (9-pin male ports) and no USB ports, then you would need to get a PCI USB card installed into your system.

No. If they were, we wouldn't have replaced them. USB and FireWire are over 3000 times faster with the latest revisions.
No. Both COM ports and USB ports are serial interfaces, but the COM interfaces are driven by single device UARTs.
