What is Networking layer ?

At OSI model Network Layer is the third layer.
It handles the service requests from the transport layer and forward to the data link layer.
It translates the logical address into physical address.
It manages the traffic problems such as routing, switching and controls of data pockets and determines the route from the source to the destination.
Network Layers main role is to move the packets from sending host to the receiving host.
The main functions performed by network layers are Routing, logical Addressing, Internetworking, Fragmentation.
In Network Layer if packet reaches the router’s input link, the router will move the packets to the router’s output link.
Logical addressing is also used to distinguish between destination and source system.
In Network Layer Internetworking is the main role that provides the logical connection between different types of networks.
Fragmentation is a process of breaking the packets into the smallest individual data units that travel through different networks.

What are Networking protocols ?

It is a set of rules that determines how data is transmitted between devices in same network.
It allows connected devices to communicate with each other, regardless of any differences in their structure, design or internal processes.
Network protocols are the reason you can easily communicate with people all over the world, and it plays a critical role in modern digital communications.

There are various types of protocols that support a compassionate and major role in communicating with different devices across the network, they are:

It is used for communicating over a network and becomes a popular communication protocol.
It separates any message into series of pockets where sent from source to destination and there it gets reassembled at the destination.

It is mostly used with TCP and designed explicitly as addressing protocol.
In network IP addresses in packets help in routing them through different nodes until it reaches the destination system.

It is substitute communication protocol to TCP implemented primarily for creating low-latency and loss-tolerating linking between different applications.

Simple Mail Transport Protocol is designed to distribute and send outgoing E-mail.

It allows users to transfer files like text files, multimedia files, program files and documents from one machine to another.

In this HTML tags are used for creating links and it is designed for transferring a hypertext among two or more systems.

It is a standard protocol to secure the communication among two computers one using the browser and other fetching data from web server.
HTTPS is used for transferring data between the client browser (request) and the web server (response) in the encrypted format.

It is designed for connecting one system with another and here the connecting process is termed as remote login.
Here the local computer system request for connection and remote computer system accepts the connection.

It is a collection of rules implemented for retrieving, searching as well as displaying documents from isolated sites and also works on the client/server principle.
