How many pairs of stations can simultaneously communicate on ELAN? - Answers

In an Ethernet Local Area Network (ELAN), all stations can potentially communicate simultaneously with each other in a shared medium. However, due to the nature of Ethernet, only one pair of stations can effectively transmit data at any given moment to avoid collisions. Therefore, while multiple pairs can attempt to communicate, only one successful transmission occurs at a time unless using switches that create separate collision domains, allowing for multiple pairs to communicate simultaneously.
