How many pairs of stations can simultaneously communicate on Ethernet LAN? a) 1 b) 2 c) 3 d) multiple
Understand the Problem
The question is asking about the number of pairs of stations that can communicate at the same time on an Ethernet LAN. This relates to the network topology and configurations that allow or limit simultaneous communication between devices.
Answer
1 pair
On Ethernet LAN, only 1 pair of stations can simultaneously communicate.
Answer for screen readers
On Ethernet LAN, only 1 pair of stations can simultaneously communicate.
More Information
Ethernet LAN uses a method called Carrier Sense Multiple Access with Collision Detection (CSMA/CD) to handle communications. This method ensures that only one pair of devices can communicate at any given time without collisions.
Tips
A common mistake is to assume that 'multiple' pairs can communicate simultaneously based on modern high-speed and switched networks, but traditional Ethernet used CSMA/CD allowing only one pair at a time.
