Data Link Layer - GeeksforGeeks
Sep 30, 2024 · The data link layer is the second layer from the bottom in the OSI (Open System Interconnection) network architecture model. It is responsible for the node-to-node delivery of data. Its major role is to ensure error-free transmission of information.
The OSI Model – The 7 Layers of Networking Explained in Plain …
Dec 21, 2020 · Links connect nodes on a network. Links can be wired, like Ethernet, or cable-free, like WiFi. Links to can either be point-to-point, where Node A is connected to Node B, or multipoint, where Node A is connected to Node B and Node C.
Data Link Layer | Layer 2 - The OSI-Model
The data link layer or layer 2 is the second layer of the seven-layer OSI model of computer networking. 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.[1]
What is the data link layer? Definition from SearchNetworking
The data link layer is the protocol layer in a program that handles how data moves in and out of a physical link in a network. The data link layer is Layer 2 in the Open Systems Interconnection (OSI) architecture model for a set of telecommunication protocols.
What Is a Data Link Layer? - Coursera
Sep 4, 2024 · The data link layer creates and disbands communication points between network devices and is responsible for how systems communicate over a network. The seven layers of the OSI model all work together and encompass functionality ranging from the physical setup to how apps run on the user interface.

Networking 101: Understanding the Data Link Layer
Jul 23, 2008 · Layer 2, the Data Link layer, is where Ethernet lives. We’ll be talking about bridges, switching and VLANs with the goal of discovering how they interact in this part of Networking 101. You don’t really need to study the internals of Ethernet to make a production network operate, so if you’re inclined, do that on your own time.
3. The Data Link Layer – Telecommunications and Networking
According to IEEE 802 Standards, the data link layer is divided into two sublayers. The first sublayer is the logical link control (LLC), and the second is the media access control (MAC). On the second sublayer, MAC addresses are used by the data link layer to establish a communication channel.
1.4: The Link Layer - Engineering LibreTexts
Sep 26, 2021 · The link layer is responsible for moving data directly from one physical location to another. It thus gets involved in several distinct issues: physical transmission, framing bits and bit sequences, detecting transmission errors, multiplexing the link, and providing a useful interface to the network layer above.
5.6. Link Layer — Computer Systems Fundamentals - JMU
Link Layer ¶. The Internet layer determines the logical path that packets will traverse through a local network and the Internet as a whole. The link layer defines the protocols that control how the bits are transmitted across an underlying physical technology.
