Final answer:
Token Ring is the network technology that allows each connected station to transmit messages at fixed time intervals, differentiating it from Ethernet and Wi-Fi.
Step-by-step explanation:
The network technology that ensures access for transmission of messages at regular or fixed time intervals is Token Ring. Unlike Ethernet and Wi-Fi, which use different methods of managing traffic and collisions on the network, Token Ring designates a token to each station in the network. This token rotates around the network's stations in a logical ring formation, and only the station holding the token can transmit a message at a given time. This system of token passing facilitates a predictable and orderly access method for each station to communicate, adhering to fixed time intervals for message transmission.
