Answer:
This is false
Step-by-step explanation:
When we have ethernet employing the csma/cd protocols at data link later then the answer is that collisions can occur.
Data link later gives several means for data transfer between network entities Which could give the means for detecting and correcting errors that could happen in the physical layer. Ethernet is a data link protocol that is used for local area networks. Data link protocols provide specifications on how devices can detect and also recover from collisions that may occur when devices try to use a medium simultaneously.
