Layered Network Architecture
Data Encapsulation
In computer networking, encapsulation is the process where data moves down the protocol layers on a sending device, with each layer wrapping the data in its own header. On the receiving device, this process is reversed as data moves back up through the layers and each header is stripped away in turn.

In a modular layered network model, modifying or updating an individual layer requires re-engineering the entire network stack simultaneously.
An engineering team is planning to update an individual protocol layer in their network stack. Based on the principles of modular layered network architecture, explain how this update can occur independently. In your explanation, be sure to address:
- The overarching purpose of structuring network systems into modular layers.
- The functional dependency between the layer being updated and the layer immediately beneath it.
- Why the updated layer must continue to fulfill its dedicated function

During data encapsulation on a sending device, what happens as data moves down the protocol layers?
On a receiving device, data moves back up through the protocol layers and each header is stripped away in turn.
Compare what happens to data and headers on a sending device versus a receiving device during network communication.
Match each encapsulation-related term or device role to its corresponding description.
Order the steps of data movement and header handling from initial transmission on a sender to final processing on a receiver.
What happens to headers as data moves back up through the protocol layers on a receiving device?
During encapsulation on a sending device, data moves up the protocol layers as each layer adds its header.
In computer networking, what does each protocol layer wrap around data as it moves down a sending device?
Match each network communication action to the corresponding layer movement and device role.
The networking process where data moves down the protocol layers on a sending device, with each layer wrapping the data in its own header, is called ___.
