【Talking over the internet by packet.】

《A way of exchanging packet which possesses a circuit jointly》

When being forwarded the packet,tiny information,each packet itself looks for an opening space in the circuit,and it's forwarded finally.😃

In this way, opening space in the circuit is utilized efficiently,so the way of exchanging packet is more effective than that in the circuit of the dial phone,or push button one.🎉

Conditions in the circuit change every moment,a packet which used to be a piece of information is sometimes forwarded through other circuit.😱

Then the packet is forwarded with a header prevent the packet from losing.The header is a kind of information which includes its address and function of avoiding an error.🙋

The header makes the packet reach a correct receiver even if it goes through any rottes,as a result,the packet is constructed as information again.😲
