About the network layer and how it works

 The networking layer helps us transfer data we want to communicate from one place to another. There are two types of layers: TCP and OSI. We mainly talk about OSI layers because there is only one difference between TCP and OSI: Three layers of OSI are mentioned as one in TCP. We will look at this in this blog let's start with OSI layers that we can understand in-depth.

Types of Layers in OSI Model

Application layer:- This layer the where the website or application is hosted. 

Presentation layer:- In this layer, is used for encryption, translation, and compression between the applications.

Section Lyer:- In this layer which manages the communication till the end.

Transportation layer:- The layer that gets transported to the server using a data link. Here TCP or UDP protocol is handled.

Data link:- This links the data to a server using a data link to connect the other server.

Physical layer:- This is the layer that we can see with our eyes (eg: Switch, hub, etc.).

Similarly this from down to up happens on the developer side and comes back to down and gives the data that is needed for the client. 

This is how network flow works in this world.
