NETWORK TOPOLOGY	NETWORK ARCHITECTURE

BUS TOPOLOGY  A BUS NETWORK CONSISTS OF A SINGLE CENTRAL CABLE (BACKBONE/TRUNK), TO WHICH ALL COMPUTERS AND OTHER DEVICES CONNECT (NODE). THE BUS IS THE PHYSICAL CABLE THAT CONNECTS THE COMPUTERS AND OTHER DEVICES.

TRANSMIT DATA , INSTRUCTIONSAND INFORMATION (DII) AS A SERIES OF SIGNAL IN BOTH DIRECTIONS WHERE ALL NODES RECEIVE THE SIGNAL BUT ONLY INTENDED RECIPIENT WILL ACCEPT THE REST WILL IGNORE.

RING TOPOLOGY A CABLE FORMS A CLOSED LOOP (RING) WITH ALL COMPUTERS AND DEVICES ARRANGED ALONG THE RING. DATA TRANSMITTED FROM DEVICE TO DEVICE AROUND ENTIRE RING IN ONE DIRECTION (CLOCKWISE OR ANTICLOCKWISE) AND REACH ITS DESTINATION USING TOKEN.

STAR TOPOLOGY ALL COMPUTERS AND OTHER DEVICES ON THE NETWORK CONNECT TO CENTRAL DEVICE (SWITCH/HUB) THUS PERFORMING A STAR.
