Solution-1:
In TCP/IP protocol architecture, four parts of protocol data unit at application later it is Data, at
transport layer known as Segment, Internet layer known as Packet, at data link layer it is frame,
and at physical layer, it is known as bits.
(Source: ccnablog, 2018)
As in diagram above, different form of the data at each layer of TCP/IP model is called protocol
data unit. Data bind in next packet with header information of particular layer. Each layer have
own header. Headers have small information about that data. Therefore, at the end all header and
data converted in row bits and transfer from physical media ( Fall & Stevens, 2012).
