Encapsulation and decapsulation in Computer Networks - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the sentence to explain encapsulation in networking.

Computer Networks

Encapsulation is the process of adding [1] to data as it moves down the layers of the OSI model.

💡 Hint

Common Mistakes

Confusing encapsulation with encryption or compression.

Encapsulation adds headers and sometimes trailers to data at each layer to prepare it for transmission.

2fill in blank

medium

Complete the sentence to explain decapsulation in networking.

Computer Networks

Decapsulation is the process of [1] headers and trailers from data as it moves up the layers of the OSI model.

Acompressing

Badding

Cencrypting

Dremoving

💡 Hint

Common Mistakes

Thinking decapsulation adds headers instead of removing them.

Decapsulation removes headers and trailers to extract the original data as it moves up the layers.

3fill in blank

hard

Fix the error in the explanation of encapsulation.

Computer Networks

Encapsulation happens when data moves from the [1] layer in the OSI model.

Cphysical to application

Dnetwork to transport

💡 Hint

Common Mistakes

Reversing the direction of data flow during encapsulation.

Encapsulation occurs as data moves down from the application layer to the physical layer, adding headers at each step.

4fill in blank

hard

Fill both blanks to describe the order of encapsulation and decapsulation.

Computer Networks

During encapsulation, data moves [1] the OSI layers, and during decapsulation, data moves [2] the OSI layers.

💡 Hint

Common Mistakes

Mixing up the directions of encapsulation and decapsulation.

Encapsulation moves data down the OSI layers adding headers, while decapsulation moves data up removing headers.

5fill in blank

hard

Fill all three blanks to complete the dictionary comprehension representing encapsulation steps.

Computer Networks

encapsulation_steps = { [1]: 'Add header' for [2], [3] in [('Application', 'Data'), ('Transport', 'Segment'), ('Network', 'Packet')] }

Drag options to blanks, or click blank then click option'

Bstep

Ddata

💡 Hint

Common Mistakes

Using the same variable name for different blanks causing confusion.

The comprehension maps each layer to the action 'Add header' for the data at that step.
