Computer Networking
Phase shift keying (psk) method is used to modulate digital signals at 9600 bps using 16 levels. Find the line signaling speed (i.e., modulation rate)
by employing wide bandwidth circuits for the trunk networks substantial economies through extensive sharing of capacity could be achieved.
the subdivision of information into individually addressed packets in conjunction with alternative routing arrangement enabled the transmission path to be altered in the event of congestion or individ
the employment of additional intelligence within the network enabled more sophisticated error control and link control procedures to be applied
