A couple posts ago, we talked about Layer 1 of the OSI Model — the Physical Layer. Today, we’ll start our climb up the Model with a visit to Layer 2, the Data Link Layer .

Understanding Protocols and the OSI Network Model. ... (IEEE) world, the 802.2 standard breaks the Data Link layer into sublayers, called the Media Access Control (MAC) and Logical ...

Phil Hippensteel provided the following: The data link level, is one which is particularly important in the delivery of audio and is used in every implementation of TCP/IP. Layer 2 (L2), the data link ...

Flow control: If the rate at which the data is absorbed by the receiver is less than the rate produced at the sender, the data link layer imposes a flow control mechanism to prevent overwhelming the ...

Using an open debug interconnect model to simplify embedded systems design. Technology people are generally familiar with the Open SystemsInterconnection model for computer networks and protocols, ...

As a matter of fact, when I started writing this post I titled it “Layer 4 of the OSI Model – understanding the application layer,” and then I had to go back and correct myself.

Ethernet is a layer 2 data link protocol that is widely used with the TCP/IP protocol, which resides at layers 3 and 4. To understand network communications, it is essential to learn about the ...

Ethernet and Token Ring are examples of this layer. Many people neither use the term PDU nor the term frame, but call every unit of data traveling over a network a "packet." See OSI model and packet .

In the Institute of Electrical and Electronics Engineers (IEEE) world, the 802.2 standard breaks the Data Link layer into sublayers, called the Media Access Control (MAC) and Logical Link Control (LLC ...
