IP(Internet Protocol) is the primary network protocol allows us to create very large Internetwork by connecting individual networks together. when we send data between devices on different network, The data is routed between networks using IP. This permits us to view even a huge Internet work such as global Internet as if it were just a single large network. IP function at layer of OSI model it can therefore run on different data link interface including Ethernet and Wi-Fi. data on IP network is organized into packets. each packet includes both a header(source, destination and other information about data) and message itself.
IP/TCP three layers:-
* IP - its responsible for moving packet of data from node to node. IP forwards each packets based on a four byte destination address( IP number). IP operates on gateway machine that move data from department to organization to region and then around the world.
* TCP(transmission control protocol) - its responsible for verifying correct delivery of data from client to server. data can be lost in the intermediate network. TCP adds support to detect errors or lost data and to trigger retransmission until the data is correctly and completely received.
* Sockets - its a name given to the packages of subroutines that provide access to TCP/IP on most systems.
