Data Encapsulation

Question 1

is a process wherein a new string of information is added to an existing unit to form a new unit of information.

A new datagram is formed by adding headers and trailers to a data payload.

Answer 1

Encapsulation

Question 2

is the reverse process of encapsulation wherein the header and tail of a packet are removed to obtain data payload.

Answer 2

Decapsulation

Question 3

can be considered as the information to be transmitted.
In a hierarchical communication process, the data unit (packet) transmitted from the upper layer to the lower layer can be called the data payload of the lower layer

Answer 3

Data payload

Question 4

is a data unit that is exchanged and transmitted on a network. It is in the format of header+data payload+tail.

During transmission, the format and content of packets may change.

Answer 4

Packet

Question 5

is the information segment added before the data payload during packet assembly to facilitate information transmission.

Answer 5

Header

Question 6

is the information segment added after the payload to facilitate information transmission.

Answer 6

Tail
