Data Link Layer
LAPD
The OSI Model is a valuable tool because it provides a standardized framework for understanding and designing network architectures. By dividing network communication into seven distinct layers, it helps troubleshoot and isolate issues, ensuring that each layer can be developed and modified independently. This modularity also facilitates better interoperability between diverse systems and technologies, enhancing overall network efficiency and performance. Additionally, it serves as a common language for IT professionals, fostering clearer communication and collaboration.

In the networking profession, the Internet Engineering Task Force (IETF) is highly respected for its technical papers and standards, particularly its Request for Comments (RFC) documents that define protocols and best practices. The Institute of Electrical and Electronics Engineers (IEEE) also holds significant authority, especially for standards related to networking technologies like IEEE 802.3 (Ethernet) and IEEE 802.11 (Wi-Fi). Additionally, the International Organization for Standardization (ISO) contributes important standards, such as those in the OSI model. These organizations collectively shape the foundational principles and protocols that govern networking practices globally.
Data Link Layer
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.

Layer 2 or the 'Data' layer of the OSI model encapsulates either 'bits' from the physical layer (1)- moving up the TCP stack or 'Packets' from the Network layer (3)- going down the the stack. 7 - Application Layer DATA 6 - Presentation Layer DATA 5 - Session Layer DATA 4 - Transport Layer SEGMENT 3 - Network Layer PACKET 2 - Data Layer (Incorporating LLC and MAC) FRAME 1 - Physical Layer BIT A good nmemonic for remembering the data encapsulation in the OSI model is 'Don't Some Peolple Fry Bacon' - Data, Segments, Packets, Bits.
The role is to transfer frames to packets

Network Layer
It works the same on all Layer 1 media. IP encapsulates OSI Layer 4 data. IP can carry voice, video, and other types of data, but "media independent" refers to the OSI Layer 1 medium that carries the data across the networks. IP, or any other communication, can occur without a physical (OSI Layer 1) medium
Networklayer
The OSI layer that handles IP addresses is the Network layer, which is the third layer of the OSI model. This layer is responsible for routing packets across different networks and managing logical addressing, such as IP addresses, to ensure that data can be sent and received between devices on different networks. Additionally, it facilitates the selection of optimal paths for data transmission.
