DESIGN AND IMPLEMENTATION OF AN ONLINE CHAT SYSTEM
Chapter one
INTRODUCTION
The chat system is a peer-to-peer system that allows users to share text messages and data. The system user is defined as client-server. A chat system is a distributed programming framework that consists of two distributed components: a chat server and a chat client.
Chat client supports various communication methods, including receiving chat server location information from a location server and displaying received chat messages. The chat server will manage all chat clients as well as conduct chat sessions.
The chat client initiates the chat session by asking the communication parameters (server name and port number). There are two types of communication between client and server: control messages (used to join and leave chat sessions, create chat rooms, and switch between chat rooms) and chat messages (only supports public chat messages).
A chatting system uses two transport protocols: Transport Control Protocol (TCP) and User Datagram Protocol. TCP handles control messages, whereas UDP handles conversation messages.
A chat system is a type of communication that uses computer programmes to enable two-way talks between users in real time. Typically, users will connect to a chat server using a chat client and gather in a chat room.
Once in the same chat room, users can communicate with one another by typing messages into a window that is visible to all other users in the chat room. The user can also view all of the messages written by other users.
Conversations continue by reading and replying to messages entered by other users in the chat room. How does online chatting work? Chat servers and chat clients are the technologies that enable users to communicate in real time using typed messages.
These unique servers enable messages to be swiftly received and posted, allowing chat applications to receive and show messages in the users’ PCs’ windows. Fortunately, most chat clients are affordable shareware programmes, and a number of chat servers allow users to connect for free.
Online chat could be a viable replacement to traditional classroom meetings. While all of the participants would be able to freely talk with one another, they would do it from the comfort of their own homes, avoiding the cost and trouble of travelling to another location.
A chat server is a specially configured computer that is connected to the internet and allows users of chat clients to communicate with one another in real time via typed messages. A large number of chat servers allow users to connect for free. Some of the more popular chat servers include dal.net and under.net. The chat resources provide a list of numerous chat servers.
Teleconferencing, sometimes known as chatting, is a technology-based means of bringing people and ideas together across geographical obstacles. The technology has been available for many years, but its acceptance is relatively new.
Our project is an illustration of a chat server. It consists of two applications: the client application, which runs on the user’s PC, and the server application, which runs on any PC on the network.
To begin talking, the client must connect to the server, where they can practise two types of chatting: public (messages are broadcasted to all connected users) and private (messages are only sent between two users), with security precautions in place for the latter.
