Aim: Write a program to Build Client-Server Model on different computers. Apparatus (Software): Eclipse/ Netbeans Procedure: Following should be studied to understand this practical What a client is and what is a server? • Client - A client is a single-user workstation that provides presentation services and the appropriate computing, connectivity and the database services and the interfaces relevant to the business need. • Server- A server is one or more multi-user processors with share memory providing computing, connectivity and the database services and the interfaces relevant to the business need. Fig: Client Server Model The protocol is the client requests the services from the server; the server processes the request and returns the result to the client. The communication mechanism is a message passing InterProcess communication (IPC) that enables the distributed placement of the client and server processes .   The distinguishing charact...

Aim: Installation & Configuration of NS2 in Linux environment and building basic LAN topology in NS2.    Apparatus (Software): NS2 simulator. Procedure: Following should be studied to understand this practical. NS2 (Network Simulator version 2) 1. What is Network Simulator? Setting up a network to do some real experiments is the best way for studying about communication in internet. However, setting a network is not easy and costly. For this reason, a virtual network provided by network simulator is used for experiment in only one computer. Specially, NS2 which is free and easy to use is the popular all over the world. For example, to observe the communication between A,B,C,D in a network as shown in Fig. 1(a), we can set up a network topology as shown in Fig.1(b) for simulator to do experiment. (a) The reality network (b) The network for simulation      2. NS2 Manual NS2 use Tcl language ...
