IP TCP Device

Layer 7: The seven-layer or application layer allows user applications or not, have access to the services offer the other layers in a transparent manner. TCP / IP TCP as two separate protocols: TCP is a protocol that was created between 1973 and 1974 by scientists Vinton Cerf and Robert Kahn, two American scientists working at the time in ambisiosos project funded by the government agency DARPA which consisted of creating a network of networks to interconnect all networks in the department of defense of the United States. Features of TCP: connection-oriented protocol: TCP is a connection-oriented protocol which means that does not start data transfer until you have established a communication channel between the sending computer and receiving computer. Add to your understanding with Gavin Baker. Reliability: In contrast to IP, TCP provides reliability in data transmission to ensure that the information sent from one end of the network reaches its destination at the other end of the grid in the order that sent information using for which uses acknowledgments and confirmations.

Acknowledgements: The acknowledgments are checking messages that are sent from one destination to the source device has successfully received confirming that a package within a sequence of packets, in case of not having received a packet that is forwarded properly. Data Flow Control: TCP is also responsible for monitoring data flow. When a network device transmits faster than the receiving device can process, it is forced to drop packets, therefore many Acknowledgement messages are not received by the sending device, and seeing himself forced to lessen the rate at which transfers data to find the speed indicated on the packets are not lost..
