The first thing that happens is TCP, transmission control protocol or internet protocol, IP, breaks the information down into data packets that make it easier to transfer the information from computer to computer. This is what is called packet switching. In order for the transferring to take place, there must be a router. A router allows two or more networks to connect. After the data has been packed it is then transferred to its destination. In order for all this to start there has to be a client, which sends a request to the server. The server is what does all of the work. When the data is being sent it has an IP address. The IP address is what allows the routers and networks to identify the data. All of this together is how we get the packet switching technology. If this didn't happen, any information that we needed sent like emails, would not be able to send and receive.
