Program Plan Intro

Access method:

  • The bus topology network needs some controlling techniques for access of particular devices to the bus.
  • For transmitting information, a Programmable Logic Controller (PLC) will access the network by using access method.
  • The access method on a network is capable of controlling the access of a particular device data to the bus.
  • The most common access methods include token passing, collision detection, and polling.

Blurred answer
Students have asked these similar questions
Discuss how contention, polling and token passing access methods perform on high and low network tra
Define the protocols used by (central) hub polling and token passing polling schemes and compare their throughput performance
Compared to the token-passing protocol, the polling protocol ismore suitable for mobile networks.
