In networking, what is the term used for the encapsulated data unit created at the Data Link Layer, containing headers and trailers?

Correct option is C

At the Data Link Layer, the encapsulated data unit is known as a Frame. Frames contain headers and trailers that include essential information for data transmission and error checking across the network link.
Important Key Points:
1. Encapsulation at Data Link Layer: Frames encapsulate data specifically at the Data Link Layer, ensuring reliable communication over physical links.
2. Headers and Trailers: The frame includes headers and trailers for addressing and error detection, supporting data integrity.
3. Network Efficiency: By structuring data into frames, the Data Link Layer ensures that data is effectively managed across network nodes.
Knowledge Booster:
· Packet: Used at the Network Layer, encapsulating data for routing across multiple networks.
· Segment: Created at the Transport Layer, containing data units for transmission with error-checking mechanisms.
· Data Unit: A generic term for data being transmitted, but does not specify encapsulation at the Data Link Layer.
· Block: Not specific to data encapsulation in networking; typically refers to storage or memory units.
