Layer 2 and Layer 3 refer to different parts of IT network communications. The ‘layers’ refer to how you configure an IT network, and the standard for network communications called the OSI model. The reason we are having a discussion about layer 2 or layer 3, is that your choice of either layer has advantages and disadvantage in terms of

Jan 27, 2008 · Dividing the Network Access Layer with the OSI Model. The TCP/IP model only has four layers as compared to the OSI model’s seven. The Network Access Layer in particular is subdivided into two separate layers in the OSI model. Because this aids in learning, we will be working with the OSI model in this section. Network layer, or OSI Layer 3, provides services to exchange the individual pieces of data over the network between identified end devices. To accomplish this end-to-end transport, Layer 3 uses four basic processes: Addressing, Encapsulation, Routing, Decapsulation Layer 2 and Layer 3 refer to different parts of IT network communications. The ‘layers’ refer to how you configure an IT network, and the standard for network communications called the OSI model. The reason we are having a discussion about layer 2 or layer 3, is that your choice of either layer has advantages and disadvantage in terms of 1 Network Layer: Network Layer and IP Protocol CSE 3213, Winter 2010 Instructor: N. Vlajic Required reading: Garcia 7.3.3, 8.1, 8.2.1

These layer’s descriptions and functions are stated below: Network Interface Layer. This consists of the data link layer which is responsible for the detection and correction of possible errors; and the physical layer that activates the physical transmission for bit transmission by procedural, electrical, mechanical, and functional means.

The network layer provides the functional and procedural means of transferring variable length data sequences from a source to a destination via one or more networks, while maintaining the quality OSI Model: The Network Layer - YouTube

OSI model - Simple English Wikipedia, the free encyclopedia

The Network layer adds a header including the source and destination IP address to generate a packet. This packet is then sent to the Data Link layer. Data Link Layer. The Data Link layer adds a header containing the MAC address information to create a frame. The frame is then sent it to the Physical layer to transmit the bits. Network layer, layer 3 - IBM The most significant protocol at layer 3 (also called the network layer) is the Internet Protocol, or IP. IP is the standard for routing packets across interconnected networks--hence, the name internet. It is an encapsulating protocol similar to the way Ethernet is an encapsulating protocol. If we view the original check as a unit of data needed to be sent, we now have two envelopes required
