3. INTRODUCTION
• Our project is an example of chat application which is basically based on public chatting
(message is broadcast to all connected users).
• It is made up of two applications:- client and server.
• Client application runs on user’s PC.
• Server application runs on any PC within the network.

4. MODULES
• Chat Client:-
The chat client is what the user experiences. A desktop, web or smartphone chat application, the
chat client is responsible for interacting with the operating system. Interactions include sending
push notifications, displaying data to the user and storing messages and files. When you type a
message and hit send, the chat client transmits that message to the server.

5. MODULES
• Chat Server:-
The chat server is just that hosts all the software, frameworks and databases necessary for the chat
app to operate. This server is responsible for securely receiving a message, identifying the receiver
and then forwarding the message to the client.

6. MODULES
• Chat rest API:-
A Chat REST API is used to facilitate the functionality of the chat app outside of messaging. For
example, authentication, profile settings and notification settings can all be managed through a
REST API.

7. HARDWARE SPECIFICATIONS
• Dual-core processor
• 4GB RAM
• SSD with sufficient space for application and data storage
• Wired or wireless network for internet connection
• Integrated graphics are generally sufficient for a chat application. Dedicated graphics are
not typically necessary unless the application involves multimedia processing.

8. SOFTWARE REQUIREMENTS
• Windows, macOS or Linux distributions are common choices.
• Support for popular web browsers such as Google Chrome, Mozilla Firefox, Safari or
Microsoft Edge is essential if the chat application is web based.
• A stable and reasonably fast internet connection is necessary for real time communication
and message delivery.
• If the chat application is a standalone desktop application, users may need to install the
application specific to their operating system.

9. FRONT END
JavaScript: If you want to create applications that can work on web, you can use React and
React Native.
React (A frontend JavaScript framework for building interactive applications)

10. BACK END
• PHP: An excellent option for web applications, particularly those created using
WordPress.
• Java: A popular go-to option.
• JavaScript: A good choice, particularly.js and the ability to write both frontend and
backend in the same language
