This layer is the protocol layer that transfers data between adjacent network nodes in a wide area network (WAN) or between nodes on the same local area network (LAN) segment.

It is responsible for the node-to-node delivery of data. Its major role is to ensure error-free transmission of information. DLL is also responsible for encoding, decode and organizing the outgoing and incoming data.

Introduction to Data-Link Layer | PPT Abdullaziz Tagawy Head of Technical Performance Auditing Unit at LIBYAN INTERNATIONAL TELECOM COMPANY The TCP/IP protocol suite does not define any protocol in the data-link layer or physical layer. These two layers are territories of networks that when connected make up the Internet. Do you want to learn more about the link layer and LANs in computer networks? Check out this PowerPoint presentation by Kurose and Ross, adapted for the ENSC 835 course at Simon Fraser University. You will find clear explanations, examples, and diagrams of the main concepts and protocols.

Data Link Layer. Data Link Layer Introduction. The data link layer sits between the physical layer and the network layer.The data link layer accepts messages from the network layer and controls the hardware that actually transmits them.Both the sender and receiver have to agree on the rules or protocols that gove. 1.18k views • 67 slides Presentation Transcript. DATALINK LAYER. Data Link Layer • Provides a well-defined service interface to the network layer. • Determines how the bits of the physical layer are grouped into frames (framing). • Deals with transmission errors (CRC and ARQ). • Regulates the flow of frames. • Performs general link layer management.

The "PPT: Data Link Layer Computer Science Engineering (CSE) Questions" guide is a valuable resource for all aspiring students preparing for the Computer Science Engineering (CSE) exam. It focuses on providing a wide range of practice questions to help students gauge their understanding of the exam topics. Data Link Layer In the OSI model, the data link layer is a 4 th layer from the top and 2 nd layer from the bottom. The communication channel that connects the adjacent nodes is known as links, and in order to move the datagram from source to the destination, the datagram must be moved across an individual link.
