INTRODUCTION :-

A PC based Net Conferencing System is to be developed in this project. Firstly, a Server ha be achieved and then a port number is provided to the server that will act like a un

connection between server and the different clients. Using this, information can be transfe

between different clients through the server end.

As the project is based on the technique of Socket Programming. So, there are two diffe

programs in this project i.e. The Server and The Clients. With the help of the common platf

(Server) different clients can communicate with each other. We can chat with as much client

we want.

The main concept of Net Conference is developing the conference on the net. We can comp

the Net conference with the Telephone Conference. Normally in Telephone Conference, th

will be more than two users connected at a time and all the users are able to here words fr

any one of the user. So implementing the same concept on the Net is nothing but

Conference.

Net Conferencing lets us bring our meeting to the Internet so we can present to hundrsimultaneously or collaborate with others on meeting materials right from our computer wh

discussing them via audio conference.

PROGRAMMING LANGUAGE :-

A programming language must have a compiler inside it whichconverts the human readable instructions into machine binary

code.

JAVA implements platform independent by implementing

platform specific JVM (Java Virtual Machine). These JVMs

contains specific instructions to execute the binary file on the

particular platform.


5/25

Java Virtual Machine :-

The heart of the Java platform is the concept of a "virtual machine" that executes Jav

code programs. This byte code is the same no matter what hardware or operating syste

program is running under. There is a JIT(Just In Time) compiler within the Java Virtu

or JVM. The JIT compiler translates the Java byte code into native processor instructions a

time and caches the native code in memory during execution.

Java virtual machine provides environment for a program to execute. Basically it provides mem

tackles memory management issues, invoke garbage collection etc.

Java Runtime Environment :-

JRE (Java Runtime Environment) provides full runtime environment to execute the Java

program, apart from providing JVM it also provides class libraries like I/P, O/P classes, utilit

classes, stream classes etc.

JVM + Classes Libraries


7/25

Java Development Kit:-

JDK (Java Development Kit) provides full development environment in order to make JAVA

application . Apart from providing JRE, JDK also provides development libraries and tools li

Compiler, Debugger, Memory analyser etc.

JVM + Classes Libraries Development Libraries+

Socket Programming :-

Server : Server is a program that waits for another program, only completes after fulfilli

request.

Client : Client is a program that fulfill its requirements by connecting to a server program.

Ports : Ports are the logical addresses to differentiate among various server programs runnin

the same system / JAM.

Algorithm for creating Server Program :

Create the object of Server Socket by providing a port no.

ServerSocket ss = new ServerSocket (port_no) ;


9/25

Call the accept method of the Server Socket.

ss.accept() ;

Fetch the I/O State.

Read and Write on the Screen.

Close the Streams.

Algorithm for creating Client Program :

First create an object of socket by providing IP Address and port no.

Socket s = new Socket (ip_address , port_no) ;


10/25

Fetch the I/O Streams.

Read and Write on the I/O Streams.

Close the Streams.

Multithreading :-

Thread Level


12/25

Multithreading enables an application to divide its program into multiple processes. T processes are indivisible and can be executed by a CPU without being divided into subprocesses. These indivisible miniature processes are called Threads that can work concurren

Advantages :

If a thread gets a lot of cache misses, the other thread(s) can continue, taking advantage ounused computing resources, which thus can lead to faster overall execution, as these resouwould have been idle if only a single thread was executed.

If a thread cannot use all the computing resources of the CPU (because instructions depeneach other's result), running another thread can avoid leaving these idle.

If several threads work on the same set of data, they can actually share their cache, leadin better cache usage or synchronization on its values.


13/25

Disadvantages :

Multiple threads can interfere with each other when sharing hardware resources such as caor translation look aside buffers (TLBs).

Execution times of a single thread are not improved but can be degraded, even when onlythread is executing. This is due to slower frequencies and/or additional pipeline stages thanecessary to accommodate thread-switching hardware.

Hardware support for multithreading is more visible to software, thus requiring more chto both application programs and operating systems than multiprocessing.

SWINGS GUI :-

Swing is the primary Java GUI widget toolkit. It is part of Oracles Java Foundation Cla

an API for providing a graphical user interface (GUI) for Java programs.

Swing was developed to provide a more sophisticated set of GUI components tha

earlier Abstract Window Toolkit (AWT). Swing provides a native look and feel that emulate

look and feel of several platforms, and also supports a pluggable look and feel that al

applications to have a look and feel unrelated to the underlying platform. It has more powerfulflexible components than AWT. In addition to familiar components such as buttons, check bo

and labels, Swing provides several advanced components such as tabbed panel, scroll panes, t

tables, and lists.

EVALUATION :-

For getting the desired result we have to follow the following steps :

Run the Server Program.


17/25

Write a valid port number i.e. positive no.


18/25

Start the Server.


19/25

Run the Client Program.


20/25

Enter valid chat name and the same port number that was given to the Server program.


21/25

You can start your chat after clicking login button.


22/25

After login the information and the messages of the client will be displayed in the serverwindow.

Advantages of Net Conferencing :-

Time plays an important role in todays world. Any information is useful if it is availabl

right time. Quick and correct information at the right time needs computerization. Many scien& engineers have to spend their valuable time to attend a conference, which is going on a

distance place. So this project will help them to participate in the conferences. This project ca

used to:

Conduct conferences with their employees. So they can get online decisions from emplo

from the different branches of the company.

The another advantage is that the company is having branches throughout the country. So

will help them to communicate business affairs of the company and live meeting

conferences between their directors. They can conduct board of directors meeting.
