Explanation / Answer
3) What is the difference between packet and frames?
In Networking terms, Packets are small chunks of messages or data that are made using breaking down of a long message that is to be sent from one source machine to another destination machine. When any file or message is sent from one source to destination the data part of the file, is broken into small parts or chunks for efficient
routing through the network.
This way it follows several transmission of packets from the source to the destination for the total message to be sent to the destination. The different packets are put together in the destination on successful receipt of the packets and thus the message or data is received. A packet is not related to any specific model layer of the Networking.
A frame on the other hand, is a unit of data which is termed to be used in the 2nd layer Data Link layer of the OSI model. A frame is the unit of data which is sent from the source to the destination as a unit with complete addressing and data and the protocol it is using. A frame contains header field, data field, addresses i.e source and destination, and is transmitted bit by bit.
