The Data Link Layer is one of my favorite layers of the OSI Model. Like a father who loves ALL of his children equally, but in different ways, I also love the other layers, but Layer 2 will always ...

4. Transport layer 3. Network layer 2. Data link layer 1. Physical layer. ISO/IEC 7498 defines the OSI model. The ITU (International Telecommunication Union) standardized the model under ITU-T X.224.

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 ...

The Internet Protocol layer is comparable to layer 3 in the OSI model. The host-to-host layer is equivalent to OSI layer 4. These are the TCP and UDP (user datagram protocol) functions.

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 ...

For more details about each layer, see OSI model. TCP/IP Protocol Stack Example The sending application hands data to the transport layer, which breaks it up into the packets required by the network.

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 .
