cable, the message flows around the ring
in one direction only.

A

ring topology

67
Q

one of the methods used to transmit
data in the ring topology.

A

Token Passing

68
Q

There is no need for terminators because
there is no end to the ring.

A

Ring topology

69
Q

a special series of bits that is generated and is passed
along the network until a computer that has a need to transmit
data makes use of the token.

A

Token
