What Are Two Functions That Are Provided By The Network Layer? (Choose two.)

Firstly, the network layer provides the unique network identifier which is provided through its end devices. And the second most important function of the network layer is that it can directly transfer the data into the destination address. The data is transferred in the form of the data packets to the other side of the network.

Today, let us discuss what actually the network layer is and the functions of the network layer. Here, the main important function of the network layer is that the network layer can able to provide the host to host connection in a network.

It also provides logical addressing, routing, and then switching.

The network layer is the third layer of the OSI model, this will transfer the data to the transport layer.

Now, let us study each function of the network layer in detail. The first type of function is called host connectivity. The host connectivity is nothing but the one like, when we try to send the data or a type of message, there consists of many numbers of the processes.

Let say that we have a host and a process that is present within the host and the communication between the process to another process is called end-to-end connectivity.

These functions will be taken care of by the network layer of the OSI model. For suppose, if we have a router in between that, then it is called the hop to hop communication which will be taken care of by the data link layer.

The next type of function is called logical addressing, the logical addressing is nothing but the one having a unique address that is not equal to any of the other devices, then it is called logical addressing.

And now, let us now discuss the main concepts of the network layer that are called the switching, and the other one is called routing.

For suppose, if we have a network that is get connected to the other networks where all these networks are connected to the routers or switches. For suppose, if we have the many types of networks that get connected to all of these.

Here, when a packet is sent by the sender through a link and if we want to send the packet to the other link, this type of process we call the switching. here we are just going to switch the packet from one device to that of the other devices.

Now, let us know what actually the routing is?. The process of routing is nothing but we are just trying to create a routing table. These routing tables will be used to send the data packet to the required destination address.

Here we just create the best path in order to send the routing packet through the best path to its destination address. Here the routing is like a process where we can able to find the best path in order to send the data packets from the source to the destination address.
