TCP/IP Model
TCP/IP stands for Transmission Control Protocol/Internet Protocol and is a standard protocol suite used to facilitate communication between network devices over the internet which consists of two components TCP and IP. TCP/IP is a compact form of OSI model. Unlike the OSI model, which has seven layers, it has four layers. The data is divided into packets by the TCP/IP Model at the sender's end, and in order to preserve data correctness, the same packets must be reassembled at the recipient's end. The data is divided into four layers by the TCP/IP paradigm, which arranges the data in a sequential fashion at the sender's end and reorders it at the recipient's end. Network Access Layer: A combination of Physical layer & Data Link layer defined in OSI model, responsible for the transmission of the data between two devices over network. Ethernet protocol is used by this layer. Network Layer / Internet Layer: It is responsible to send the packets from a network to the des
