Table 7. Types of USB ports
Standard USB
Mini‑USB
The standard USB port is present on most laptops and desktops. Most USB devices connect to the
computer using this port.
A mini‑USB port is used in small electronic devices such as cameras, external storage drives, tablets, and
so on.
Rear‑surround out port—Connect multi‑channel capable
speakers.
Center/LFE surround out —Connect a single subwoofer.
NOTE: The Low Frequency Effects (LFE) audio channel,
found in digital surround sound audio schemes, carries
only frequency information (80 Hz and below). The LFE
channel drives a subwoofer to provide extremely low bass
extension. Systems not using subwoofers can shunt the
LFE information to the main speakers in the surround
sound setup.
Side-surround sound port—Connect left/right speakers.
RCA S/PDIF port—Transmits digital audio without the need of
analog audio conversion.
Optical S/PDIF port—Transmits digital audio, using optical signals,
without the need of analog audio conversion.
