Those can sometimes be difficult to distinguish 
Anyway, I haven't really given this that much thought, and I would assume there are more efficient ways of electronic communication. But maybe for some areas it is sufficient (and the speed can be increased if needed, at least to some degree, but some error-checking would preferably have to be implemented on the received data). And than there are the things Matt Adams point out.
@Matt Adams:
Thanks for pointing all that out, and also welcome to this forum 
Not that I'm "qualified" to say something like that (I'm just a random user like most here), but anyway cool that this thread got you started!
