The layer 2 devices use the data link layer addresses.
Local delivery
Data Link Layer
They are defined in the OSI layer known as Data-Link.
Layer 2 data link layer
data link layer
At the Data Link Layer, computers use MAC (Media Access Control) addresses, which are unique identifiers assigned to network interfaces for communication on a local network. These addresses are typically 48 bits long and are represented in hexadecimal format. MAC addresses facilitate the delivery of data frames between devices on the same network segment, ensuring that data reaches the correct destination within a local area network (LAN).

The OSI model has seven layers whereby each layer has its function. The Data Link Layer is responsible for addressing data messages so that they reach their destination correctly.

The Hop-to-hop delivery is also called the node-to-node delivery and it is the delivery between two nodes connected to the same network by a link and this jib is carried out by the data link layer....
Data Link
the network layer --> check your question. ^^^^^^^^^^^^^^^^^^^^^^^^^^^ That is totally not the right answer, how about you actually read the book for the course. It is the data link layer that does encapsulation. I agree - its the Data Link Layer which encapsulates the Network layer...NOT the Network Layer.
