    ABSTRACT

    Web Based Live Chat may refer to any kind of communication over the Internet that offers a real-time transmission of text messages from sender to receiver. The aim of the study is to Design and Implement a Web Based Live Chat Application that will allow users within an intranet / internet connection to engage in private and public conversations. In achieving this aim, the following specific objectives were laid out to develop a conceptual design for a secure, accessible and user-friendly web based Live Chat Application, and perform tests on the said system to assure functionality, accessibility and usability of the system. The motivation that led to the implementation of the proposed system is that, group work cannot be done independently with intermediate synchronous response from all members in the group in one location and message broadcast within split of second has always been a challenge.

    The methodology adopted in this study is the structured system analysis and design methodology (SSADM) which is a technical approach for analyzing and designing an application or system by applying object throughout the software development process. This project focuses on solving the problem by developing an application for communication services in Nigeria Society. The Live Chat Application is a web-based application intended to be accessible from the internet or intranet. This allows the application to be available to both mobile phone users and PC users who can access the internet from their devices. The Live Chat Applications system was developed using open source web technologies notably HTML, PHP, JSON, JQUERY, AJAX and MySQL. The proposed system produced in this research work has functions that will enable students, lecturers, and staff or various departments in the institution to communicate using asynchronous string transfer know as chatting between each other. The developed application was tested using the WAMP application suite and the test results show that the application works as expected.

    CHAPTER ONE

    1.1 Introduction

    Web Based Live Chat may refer to any kind of communication over the Internet that offers a real-time transmission of text messages from sender to receiver. Chat messages are generally short in order to enable other participants to respond quickly. Thereby, a feeling similar to a spoken conversation is created, which distinguishes chatting from other text-based online communication forms such as Internet forums and email. Web Based Live Chat may address point-to-point communications as well as multicast communications from one sender to many receivers and voice and video chat, or may be a feature of a web conferencing service. Several network Web Based Live Chat Communication Systems are built to communicate with one another and are made available through service-oriented architectures. In this project, we use the client server architecture to develop a secured Client-Server Live Chat Application. A Live Chat Application is created based on Transmission Control Protocol (TCP) where TCP is connection oriented protocol and in the end, multithreading is used to develop the application.

    As a prelude to other parts of this study, this chapter will discuss the background upon which this study was initiated, the statement of problems that led to this study, the Aim and Objectives of the study. Others are Significance of the study, Scope of work, Limitation of the study and Definition of technical terms.

    Defense Procedure for Computer Science Researchers

    In preparation for defending a project or seminar on Design and Implementation of a Web Based Live Chat Communication System, it is imperative that as a nursing student, you demonstrate comprehensive knowledge of your research. The defense process is structured to include presenting your work, answering questions, and illustrating its pertinence. Initially, provide a succinct yet thorough introduction to your research topic, emphasizing its importance and the objectives, ensuring that both the audience and the External Examiner can understand the scope of your study.

    Prior to your defense, be thoroughly acquainted with your research abstract and the critical elements of Chapter One, including motivation for embarking on this research, problem statement, objectives, and significance. In Chapter Two, be ready to cite at least two references from the literature review. For Chapter Three, you should be equipped to discuss the methodologies, tools, and techniques utilized. In Chapter Four, defend your research by justifying the findings and linking them to your research objectives.

    Conclude your defense by succinctly summarizing the study and offering insightful, evidence-based recommendations. A professional dress code, such as wearing a suit and tie, is vital to create a favorable impression and elevate your presentation.

    During the question and answer segment, the External Examiner may pose questions pertaining to your research. If confronted with a challenging or irrelevant question, respond diplomatically with, “Sorry, Sir/Madam, the question asked is beyond the scope of my study.” Whenever possible, direct your answers back to your research findings to reinforce your expertise.
