TCP/IP Reference Model
TCP/IP model define 4 layers that are as follows:
1) Internet layer :
Packet switching network depends upon a connectionless internetwork layer. This layer is known as internet layer, is the linchpin that holds the whole design together. Its job is to allow hosts to insert packets into any network and have them to deliver independently to the destination. They may appear in a different order than

Local Area Networks (LAN)
A single building or campus of few kilometers in size, LAN acts as
privately owned networks. LANs are limited to a single building or group
of buildings. By using telephone lines and radio waves, one LAN can be
attached to other LANs over any distance. A system of multiple
connections of LANs is called a wide-area network (WAN).
Integrated Services Digital Network
Integrated Services Digital Network is a system with digitized phone
connections, which has pure analog connection. It is the first protocol
which describes on a digital communications line. This allows
transmission of data, voice, video and graphics at very high speeds over
standard communication lines carried by bearer channels (B channels)
occupying a bandwidth of 64 kbits per second. A data channel (D channel)
handles signaling at 16 kb/s or 64 kb/s depending on the service type.
It is not limited to public
