Answer 1

Answer:

it's so easy to understand the real life example of encapsulation is :

supposed you have a vacant/empty plate

Answer 2

Answer:

It is very useful and easier to understand the concept of encapsulation. As we know the concept of encapsulation says that data flows down the protocol hierarchy, headers (and trailers) get appended to it and data moves up the hierarchy headers (and trailers) get stripped off.

Example to illustrate :-

1. TFTP client transfer 200 bytes of data.
2. 4 Bytes of TFTP header gets added.
