Data Encapsulation Method
1. User information is converted to data for transmission on the network.
2. Data is converted to segments and packaged with control information for a reliable connection.
3. Segments are encapsulated with a network header and converted to packets or datagrams, which specify the source and destination logical addresses.
4. Packets, or datagrams, are converted to frames to allow a connection over an interface to the network.
5. Frames are converted to bits with some clocking functions to allow transmission a medium.
Key Terms:
Bits: The Physical layer takes the binary data down from the Data Link Layer and converts the 1’s and 0’s to a digital signal to be sent out over the physical topological.
Frames: These house the packets, or datagrams, handled down from the Network layer to be delivered to a device on a LAN.
Packets: Sometimes called datagrams, these house the segments handed down the
Transport layer to be routed through an internetwork.
