TCP/IP MODEL:
TCP/IP Model is the mostly used model at present this model contains 4 layers of communication it is the real time model designed by Department of Defense. This real time model is designed by referring to the OSI Model . The OSI model is not used in real time communication. The TCP/IP Model stands for TRANSMISSION CONTROL PROTOCOL/INTERNET PROTOCOL model. In this model the packet transfer is ensured unlike the OSI model where the packet transmission is not ensured The four different layers of TCP/IP model are:
- APPLICATION LAYER
- TRANSPORT LAYER
- INTERNET LAYER
- NETWORK LAYER
APPLICATION LAYER:
Application layer is a combination of three layers of OSI model those three layers are Application Layer, Session Layer and presentation layer it manages user interfaces and establishes a connection between the devices. it follows protocols like HTTP, HTTPS, FTP, TELNET, SSH e.t.c
TRANSPORT LAYER:
The Transport layer of the TCP/IP model is equivalent to the transport layer in OSI model .This model ensures the delivery of error free data. This layer mainly follows two types f protocols they are
- TRANSMISSION CONTROL PROTOCOL(TCP).
- USER DATAGRAM PROTOCOL(UDP).
INTERNET PROTOCOL:
The Internet Protocol of TCP/IP model is equivalent to network layer of OSI model it is responsible for logical transmission of data over the network.it follows protocols like
- INTERNET PROTOCOL(IP).
- INTERNET CONTROL MESAGE PROTOCOL(ICMP)
- ADDRESS RESOLUTION PROTOCOL(ARP)
Network layer is the combination of physical and datalink layer of OSI model. The address resolution protocol is present in both network layer and network layer. This layer searches for the hardware regarding the communication for the transmission of the data
