Topic 4: The data Link Layer
The role of the data link layer
The data link layer can be stated as the second layer, which we related to the OSI model. Identification of the error can be stated as one of the main functionality, which is related to the data link layer. In the data link layer various activity of the networking aspect are controlled. It can be stated as one of the crucial areas due ot the factor that if errors are included into the sector of network it can directly disrupt the overall functionality of the network. There are different protocols, which are attached to the sector, which deal with the sector of working of the networking layers.
Data link in the internet model of networking
The data link layer in the internet model of networking is related to the functional and requirement which is related to the procedural. Some of the example in the context is linked to the HDLC and the point-to-point protocol. These two aspects are directly linked to the data link layer. Another important function, which is related to the data link layer, is related to the synchronization of the data, which is being passed from one sector of the network to another network.
The two parts of the data link layer
In the context of the IEEE802 local area network, the data link layer can be broadly be divided into two parts which is the media access control and the another one which is LLC which is the logical link layer. Both of the layers directly gives the provision of the IEEE 802.2 LLC, which is one of the aspects of the IEEE 802 MAC for example the token ring, IEEE 802.11 and the Ethernet.
The role of the network interface card (NIC)
The network interface card in the sector of working can be stated to be having the functionality, which is related to the connectivity factor. It directly creates a medium of communication, which directly prevails in the sector of the two devices which are in the sector of communication. It directly haves the functionality which is related to the working of the network so that communication area can be easily be achieved. Another name, which is given to the network interface card, is the network interface controller. This is due to the factor that it directly helps in the sector of working of the different later which is linked to the OSI model.
Identification of the NIC (MAC addresses)
There are different methods, which can be seen in the sector of the identification of the NIC or the MAC address. The table, which is given below directly explains the different sector which is linked to the concept.
Platform
Method
Windows NT/2000
ipconfig/ all command
Novell NetWare
Run the config command.
Windows 95/98/Me
winipcfg untility
Cisco Router
s hint command
Linux/some Unix
Run the ifconfig – a command
Network card are smart devices
The network card can be stated as a devices which directly enhances the functionality which is linked to the sector of working. In this context, it can be stated that the network card is directly put as an USB device in the system, which directly creates network connectivity, which allows the sector of communication in the network.
The network card is considered as a smart device due to the factor that it directly gives access to the sector of connectivity, which enhances the network of the working devices (Deering & Hinden, 2017). In most of the recent computer, devices it can be stated that the network card is pre-installed which can be beneficial in a manner of enhanced functionality.
Media access control
The media access control can be considered as one of the sub layer, which is related to the OSI model. It main control aspect, which is related to the concept, is linked to the sector of the controlling of the different packets of information when it is being transferred from one area to another. It can be stated as one of the crucial activity, which can be directly linked to the sector of working...
