In the structure of the client-server network we have two separate methods that are employed in information, data communications, and transfer valuable data. Every method of data communication has its own advantages and limitations. We categorize the structure of the client-server network communication in connection-oriented method and the connectionless communication methods: Connection-orientedcommunication method: This scheme needs an early communication session association (that is comparable phone call systems) which will be recognized previous to some data and information can be sent. This technique is frequently acknowledged as a dependable and more reliable network communication service. It is able to assure that information and data will reach the destination similar order. Connection-oriented communication mode and services establish (set-up) virtual connection among end systems in the course of a client-server network (Tenenbom, 1996). If you need to make certain that a particular data arrives at its destination, then this method can be used. This method gives a response to show that data was received successfully (Nash, 2000). Connectionless communication method:This is similar to the posting a letter. One the letter has been posted then there is no response regarding its arrival, whether it arrived or not. This is a faster way of communication due to less overhead (Nash, 2000). This way of data and information communication does not need a startup session association among receiver and sender. The sender just initiates the course of the transmitting data packets (those are acknowledged here as datagrams) to the destination host. This way of data communication is not as consistent as compared to the connection-oriented technique, on the other hand, it is helpful for episodic or one by on burst transfers. Neither communication systems have to uphold communication state information intended for the arrangement that they drive transmission to or take delivery of transmission from. A connectionless communication network presents minimum services.
