What will be an ideal response?
The TCP/IP consists of 5 layers. The layers and their short explanation are as follows:
? Layer 1: Physical: Protocols in the Physical layer specify details about the underlying
transmission medium and the associated hardware.
? Layer 2: Network Interface Protocols in the Network Interface layer specify details
about communication between higher layers of protocols and the underlying network.
? Layer 3: Internet: Protocols in the Internet layer form the fundamental basis for the
Internet. Layer 3 protocols specify communication between two computers across the
Internet.
? Layer 4: Transport: Protocols in the Transport layer provide for communication from
an application program on one computer to an application program on another.
? Layer 5: Application: Protocols in the top layer of the TCP/IP stack specify how a pair of
applications interact when they communicate.
