The link layer corresponds to the OSI data link layer and may include similar functions as the physical layer, as well as some protocols of the OSI's network layer. These comparisons are based on the original seven-layer protocol model as defined in ISO 7498, rather than refinements in the internal organization of the network layer.

I found your topic on Networking and Protocols very interesting. I understood very well the functions and operational flow of OSI model and TCP/IP on Internet.

OSI Model explanation. OSI model layers function is given below. APPLICATION LAYER: The application layer is the last layer of the OSI model. This layer works at the client or user side which is shown below.

The TCP and UDP transports map to layer 4 … If Layer-2 has a checksum, shouldn't this validation be enough? Why we are having checksum validation in different OSI Layers? Simply put, different layers of the OSI model have checksums so you can assign blame appropriately. Suppose there is a webserver running on some system (assume TCP port 80, i.e. OSI Layer … 2013-02-13 The upper layers of the Open System Interconnection (OSI) model, where user data is found, need the lower layers, like a train needs tracks to get from point A to B. It is these lower layers?physical, data link, and network?that provide the "railroad tracks" for the user data. ARP OSI layer : ARP stands for Address Resolution Protocol.

Besides remembering the basics of the features of each OSI layer (as in Table 2-4), and some example protocols and devices at each layer (as in Table 2-5), you should also memorize the names of the layers.

물리 계층(Physical layer)은 네트워크의 기본 네트워크 하드웨어 전송 기술을 이룬다. 네트워크의 높은 수준의 기능의 논리 데이터 구조를 기초로 하는 필수 계층이다. 다양한 특징의 하드웨어 기술이 접목되어 있기에 OSI 아키텍처에서 가장 복잡한 계층으로 간주된다.

It resolves an IP address to the MAC address of the Ethernet card. ARP is the data link layer protocol in the OSI model. DNS OSI layer : This is a domain name system. It is an application layer protocol. ICMP OSI layer: It works as a user of the IP layer.

21. ARP is layer 2. The reason being is that a broadcast is sent on layer 2 (data link layer) and ARP will normally not traverse to layer 3 (network layer). However it can provide extra features to the layer 3 protocol. The truth is that not all protocols fit the OSI model exactly, because after all it's just a model.
