USB stands for Universal Serial Bus, which means it connects peripherals
to a computer. It is an evolved form of old serial or parallel bus.
USB makes installation of new peripherals much simpler, just plug and
play. You do not have to pry open the PC to add a peripheral any more,
just plug and turn it on. With USB-compliant computers and peripherals,
there are no more worries about IRQ setting, DIP switch setting, or card
installation. Even the computer turned on, it is no problem with attaching
and removing devices. Just plug and play!
Practically, there is no limit on number of devices that can be connected to
the computer. Up to 127 peripherals can be linked to the computer using
USB hubs.
USB even provide electrical power to the peripherals. It automatically
detects necessary power and supplies it, which eliminates messy power
cables from working space.

compliant devices. Just look for a port and plug in.

the sound quality. Digital or analog, not all audio interface cards are made
the same. If you are a professional or in need of a professional quality
USB audio interface, you have made a sound investment in Waveterminal
