Describe CSMA/CD or describe the access method of Ether LANs.

CSMA/CD (Carrier Sense Multiple Access with Collision Detection): 

The IEEE 802.3 defines the Carrier Sense Multiple Access with Collision Detection (CSMA/CD) as the standard access method for traditional Ethernet. Stations in a traditional Ethernet can be connected using a physical bus or star topology, but the logical topology is always a bus. It means that the medium is shared and only one station can use it at a single time. But the problem is the assurance that only one station is using the medium at a time is solve d as follows,
