Which term refers to stripping header information as a PDU is passed from one layer to a higher layer?1 pointDe-encapsulationEncapsulationLabeling. Packetization

Sure, let's break down the question step by step:

1. Understanding the Terms:

   • Encapsulation: This is the process of adding header information to data as it moves down the layers of the OSI model.
   • De-encapsulation: This is the process of removing header information from data as it moves up the layers of the OSI model.
   • Labeling: This generally refers to adding labels to packets for identification, often used in networking for routing purposes.
   • Packetization: This is the process of dividing data into packets for transmission over a network.

2. Identifying the Process:

   • The question asks about the process of stripping header information as a Protocol Data Unit (PDU) moves from one layer to a higher layer. This means we are looking for the term that describes the removal of headers.

3. Matching the Term:

   • De-encapsulation is the correct term because it refers to the process of removing header information as data moves up the OSI model layers.

Therefore, the correct answer is:

• De-encapsulation
