Explain Logical Ring Physical Star topology for Token-Passing Standard.
It is definite that any break in the ring at any point will interrupt communications for all machines. To solve this problem, IBM developed a modified ring topology, which they say the logical ringphysical star. The central point of the physical star configuration is Token Ring hub called the multi-station access unit (MSAU, pronounced as masow).
