How does it work?
Imagine that you have made a jigsaw puzzle. You are sending each piece of the puzzle to all your classmates you had in early childhood with a message that has the date, time and place to meet. Your goal is to gather all your classmates and construct the puzzle with everyone.
Packet switching works in the same way.
The message is packaged and sent to the destination. These packets may travel along different roads. As all the packets necessary to construct the message arrive at their destination, they are reassembled into the original message.
Circuit-switching vs Packet-switching
Circuit-switching is another protocol which sends messages to others. It is normally used in telephone communication. Circuit-switching is quicker then packet-switching. However, circuit-switching needs data to be sent in order and in the same time. Packet-switching is more efficient and robust, and can withdraw some days in transmitting. For that, packet-switching is better suited for emails and websites. Circuit-switching is more useful for real-time data transmission.
