Circuit Switching
An example of a circuit switched network is a telephone network. The a remote access link for each major node in the circuit associated with a phone call is established for the duration of the call. It is also the case that the pathway taken might be different from one call to the next.
An example of a packet switching network is the standard routing operations on the Internet. When you send an e-mail it is broken down into packets. Each packet might take a different route to get to the destination. Then the packets are reassembled at the other end.
