  1. 1. T U H I N D A S P I Y U S H C H A N D E K A R V S E M E S T E R C . S . E UNDER THE GUIDENCE OF - MS. HEMA SHAHU SESSION : 2010-2011
  2. 2. 1. Literature Survey 2. Introduction to Network 3. Peer to Peer mode 4. Client-Server connection 5. Client -Server mode 6. Server Model 7. Client Model 8. Block Diagram 9. Data Flow Diagram 10. Working 11. Future Scope 12. Advantages 13. Limitations 14. Conclusion 15. References
  3. 3. 1. According to the survey made on the Network used in Small scale industries , colleges, offices and cafes. 2. LAN with Client-Server mode is mostly used network in small scale industries . 3. Here we are implementing it in large scale with hi-speed multimedia data transfer with chatting facility.
  4. 4. A network is an interconnection of computers may be wired or wireless for data communication , remote accessing , resource management and data sharing. There are two types of mode in Networking : 1. Peer to Peer Mode. 2. Server-Client Mode.
  5. 5. 1. In Peer To Peer mode each of the interconnected machines share dual capability and responsibility on the network. Each machine serves a dual purpose or role, both clients and servers to some extent. 2. As all machines on the network have equal status is no centralised control over shared resources. Sharing is endorsed or repealed by each machine's user. 3. Security can also be a major concern due to lack of centralisation and this network configuration is used in small organisations.
  6. 6. 1. Client-server networks has a machine at the heart of its operations called the server. A server is a machine that provides services over a network by responding to client requests. 2. Server-based networks provide centralised control of the entire network environment. 3. Server-based networks are easier to scale. 4. The networks operability is dependant on the server.
  7. 7. 1. Server is that computer which facilates, sharing of data software and hardware resources (ex: printers, modems) on the network. 2. A server is a program running on the remote machine providing service to the clients. 3. When it starts, it opens a door for incoming request for a client, but it never initiates a service until it is requested to do so.
  8. 8. 1. Client is the program running on the local machine requesting service from the server. 2. A client program is finite means it started by user or another application program and terminates when service is complete. 3. Server provides services over a network by responding to client requests.
  9. 9. DATA BOX. CHAT BOX. SEND CONNECT/DISCONNECT SERVER NAME/IP ADDRESS Server Model Client Model DATA BOX. SEND START CHAT BOX. EXIT CONFIGURE Functional Diagram
  10. 10. START START THE SERVER START CLIENT REQUEST TO SERVER FOR CONNECTION IS REQUEST GRANTED ? SHOW ERROR CONNECTION SUCCESSFUL A N Y
  11. 11. TRANSFER DATA IF QUIT? SEND MESSAGE LOGGED OUT SUCCESSFULLY. END A Y N
  12. 12. 1. We need to START server. 2. Then CONNECT the client with its name/IP address. 3. Once connection established Server acknowledges clients by welcome note. 4. Server and client now can exchange data in the form of media file like Music file, video file, images and simple textual data. 5. By DISCONNECT Client gets disconnected from server.
  13. 13. 1. Includes many clients. 2. Can be implemented in large network like WAN. 3. Hi-speed multimedia data transfer . 4. Control all the computer system(clients) and sub-servers in large network like INTERNET.
  14. 14. 1. Centralised user accounts, security and access controls simplify network administration. 2. More powerful equipment means more efficient access network resources. 3. Single password login, means access to all resources. 4. Supports greater numbers of users, or networks where resources are heavily used.
  15. 15. 1. More costly to install and maintain. 2. Single point of failure, server goes down, the network goes down. 3. Complex special-purpose software requires appointment of expert staff, increasing costs.
  16. 16. We have successfully completed our Project on Client-Server Communication.
  17. 17. 1. Data Communication and Networking by Behrouz Forouzan. 2. The complete reference by Herbert Schildt. 3. www.encyclopedia.com .
