0:00 – 1:18 00:00-01:18
The instructor explains the structure of an Ethernet frame, specifically focusing on the CRC (Cyclic Redundancy Check) field. The slide details that the CRC is a 4-byte field used for error detection and is calculated at the time of transmission, placing it as the last field. Visible cues include Instructor points to the CRC field in the diagram; Explanation of CRC as a 4-byte error detection field.

Across sampled screenshots, the clip stays on one visible example: The instructor explains the structure of an Ethernet frame, specifically focusing on the CRC (Cyclic Redundancy Check) field. The sampled frames keep the same example visible rather than switching to a different slide, topic, or question. The visible evidence stays centered on one stable example instead of moving through multiple separate prompts. The instructor's gestures and annotations suggest the teaching goal is to compare the visible choices carefully before confirming the answer.
