synchronous
Thetransmissionofdatabetweenatransmittingandareceivingdevice
occursasaseriesofzerosandones.Forthedatatobe"read"correctly,
thereceivingdevicemustbeginreadingattheproperpointinthe
series.Insynchronouscommunication,thiscoordinationis
accomplishedbysynchronizingthetransmittingandrecei
vingdevicesto
acommonclocksignal(seeAsynchronous
