Network Technology 1 Pre-Finals Handout 5 p1

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

• Encapsulation
• Decapsulation
• Data payload
• new datagram

formed by adding headers and trailers to a data payload

• Encapsulation
• Decapsulation
• Data payload
• new datagram

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

• Encapsulation
• Decapsulation
• Data payload
• new datagram

can be considered as the information to be transmitted In a hierarchical communication process

• Protocol Data Unit (PDU)
• Physical layer
• Data Link layer
• Network layer

It is often used in reference to the OSI model

• Protocol Data Unit (PDU)
• Physical layer
• Data Link layer
• Network layer

since it describes the different types of data that are transferred from each layer
