Answer:

Explanation:

Data is important for every organization. Therefore, it is necessary to send the data to another location easily with a minimum amount of time. The data can be sent to the destination using the network. A network is a collection of interconnected devices such as computers, printers for sharing resources. When there is a large number of hosts, the network becomes complex, connecting different computers increases the incompatibility. Therefore, open standard network models were improved. Two common network models are International Organization for Standardization (OSI) and  Transmission Control Protocol / Internet Protocol (TCP/IP). TCP/IP is the new network model that is a replacement for OSI model. These models contain layers. Data goes through the layers of data communication. Encapsulation and Decapsulation are two terms related to passing data through each layer. The key difference between encapsulation and decapsulation is that, in encapsulation, the data moves from upper layer to the lower layer, and  each layer includes a bundle of information known as a header along with the actual data while, in decapsulation, the data moves from the lower layer to the upper layers, and each layer unpacks the corresponding headers to obtain the actual data.

pls mark as brainlist if you don't mind :D

HOPE IT HELPS

HAVE A GREAT DAY!!!
