They're just boxes which can have more than two mics (or line-level
signals
eg from instruments) plugged into them. Inside there's multiple
analogue-
to-digital converters. The digital data from all of these is then sent
along
the USB connection to the computer. Some interfaces might send all the
channels so they arrive in a single file on the computer, which then
contains
multiple separate channels, others may directly generate separate files
on
the computer.
It's unimportant which you get because a file containing multiple
channels
can be split into separate files (with eg sox), or a set of files can be
combined
(with eg sox).
I can't advise you on what to buy... because I suspect you're going to
spend a
great deal less than I did when I last bought one... That was a Tascam
box:

which you'll see can handle 16 separate inputs at once... There's a
more recent
version of that these days... A box like that is aimed at people used
to using
professional audio equipment.
There will be lower-spec interfaces around too, but you obviously need
to find
one that's known to work with linux. You also probably don't want one
with
eg XLR sockets for mics.
