Each piece of information received by the IP protocol adds proprietary information of which you can see the sender and receiver information. If you follow the analogy with the post, the data is placed in an envelope or package, on which is written the address of the recipient. Further, the IP protocol as well as regular mail, delivers all packets to the recipient. At the same time speed and path of the different envelopes can be different. The Internet is often portrayed as a diffuse cloud.
You do not know the way flow of information, but properly designed IP-packets reach the recipient. The TCP protocol checks whether tainted information, and, if necessary, request retransmission of some packets. Since the individual parts can surf the Internet by different ways, the order of arrival parts may be broken. Once all the packages received and sorted, one recovers the original information. That's how the protocols TCP / IP. They provide information transfer between two computers connected to the network.
For programs that work with these protocols, the Internet is not visible. One gets the impression that the two computers are connected to each other a dedicated line, although in reality between them at high speed sent packets of information.

An example of switching network channels may serve as a telephone network. During the call, the communication channel is established between two parties, which will be broken at the end of the conversation. No one else can break into this channel of communication, and other subscribers must wait for the call. In packet-switched communication channels are shared by many users. Under heavy load all the packages will be transmitted slower, but parts of the network will not be monopolized by one person, as in circuit-switched networks. In addition, if one of the communication channels, packets can go around it, and circuit-switched connection with any failure will be lost. Network with packet is characterized by high reliability and relatively low cost of construction, which is one of the reasons for the success of the Internet.
