  3. 3. Server:  Provides services for clients.  Also known as host computer.  Controls access hardware and software on the network.  Provide storage area for programs, data and information.  User authentication and registration.  Provide access to stored data… 1/7/2014
  4. 4. Client:  Also known as users or customer.  Request the resources from the server.  Independent from other clients.  Gets the files from server.  Sends file to the server.  Delete, copy, Rename the files on the server…. 1/7/2014
  5. 5. Types Of Servers:   Application server: Dedicated to run different applications. Message Servers: Include chat rooms, group wares, provide instant and real time communication between users.  1/7/2014
  6. 6. Types of Servers Cont….    Proxy Server: Used to filter request made by user over the server. Improves performance. Database Server:  Manages database used over the network.  1/7/2014
  7. 7. Types of Servers Cont….    Web Server: Provides access to internet via HTTP. Receives request from browser and sends to main server…. 1/7/2014

  9. 9. Advantages: Reduces the volume of data traffic over the network.  Provides faster response to clients.  Allows the use of less powerful computers as clients because most of the work is done by server.  Provides more security.  Accessible any time.  1/7/2014
  10. 10. Disadvantages: Expensive model.  Operations stop across the network if server goes down.  Need of professionals to maintain.  No robustness.  Difficult to implement than P2P.  1/7/2014
  11. 11. Example:  Online Banking networks. User wants to access his account from the web browser. As his data is stored in database, web server run a program to access database. This database server may, in turn, fetch financial transaction records from another database server. An application server interprets the returned data by following the bank's business logic, and provides the output to the web server. Finally, the web server sends the result to the web browser, which interprets the data. 1/7/2014
  12. 12. Comparison with P2P network Clients Server consist of many clients but P2P consist of one client one server.  Computing power, memory and storage is more than P2P.  Scaled properly to perform any process on any query.  1/7/2014
