data encapsulation in networking ppt
Data encapsulation, sometimes referred to as data hiding, is the mechanism whereby the implementation details of a class are kept hidden from the user.
The user can only perform a restricted set of operations on the hidden members of the class by executing special functions commonly called methods.
What is data encapsulation in networking?
What is encapsulation? Encapsulation marks where a packet, or unit of data, begins and ends.
The beginning part of a packet is called the header, and the end of a packet is called the trailer.
The data between the header and trailer is sometimes referred to as the payload.26 jan. 2022
How data encapsulation works in TCP IP model?
As the packet travels through the TCP/IP protocol stack, the protocols at each layer either add or remove fields from the basic header.
When a protocol on the sending host adds data to the packet header, the process is called data encapsulation.
What is encapsulation in CCNA?
Data Encapsulation.
When a host transmits data across a network to another device, the data goes through encapsulation: It is wrapped with protocol information at each layer of the OSI model.
Each layer communicates only with its peer layer on the receiving device.
