How does data encapsulation and the protocol stack work?
A.
Each protocol or service at each layer in the OSI model multiplexes other packets to the data as they are passed down the protocol stack.
B.
Each protocol or service at each layer in the OSI model adds its own information to the data as they are passed down the protocol stack.
C.
The packet is encapsulated and grows as it hops from router to router.
D.
The packet is encapsulated and grows when it is passed up the protocol stack.
Explanation:
B: Data encapsulation means a piece of data is put inside another type of data. This usually means that individual protocols apply their own instruction set in the form of headers and trailers. As a data package goes down the OSI layers, or protocol stack, of a system, each protocol involved adds its own instructions. This process is reversed at the destination.
