Study Notes
Encapsulation
- Encapsulation is the process of wrapping data with metadata, such as source and destination addresses, to facilitate transmission over a network.
- It involves packaging data into a packet, which includes headers and payloads, to ensure efficient and secure data transfer.
Reverse Process of Encapsulation
- The reverse process of encapsulation is decapsulation, which involves removing the metadata and extracting the original data from the packet.
Datagram
- A datagram is a type of packet that is used in connectionless communication protocols, such as UDP (User Datagram Protocol).
- Datagrams are self-contained packets that contain source and destination addresses, and are transmitted independently over a network.
