Example of circuit-switching: You pick up your land phone and dial your friend. At that point, the telco provider creates a dedicated circuit for that session and connects you to your friend's telephone. No matter how long you keep the line open with your friend, the circuit will remain, and packets flowing between both telephones will always follow the same path. This is an example of a circuit-switched network.
Example of packet-switching: In the second example, you switch on your PC and connect to your favorite site that offers a number of applications you can download from, so you begin downloading one application at a time. Each packet has to find its own route to the destination, i.e., your computer. Each packet finds its way using the information it carries, such as the source and destination IP address. If network congestion occurs, the routers responsible for routing packets between networks will automatically select different paths to ensure data is transferred as required. This is an example of a packet-switched network.
Nothing
The time difference is thirteen hours...
It all depends on perspective. If you look at it as a IP network, the difference is routers used in WAN. If you take in account DNS and other Internet services, the difference is more dramatic.

The difference between internet and wan is WANs are provided by companies licensed by the government to provide communications to the general public. The largest WAN in use today is the internet, which connects many smaller networks and millions of users from around the world.
Frame Relay
From the user's point of view, accessing a LAN or WAN is the same. If packets need to be forwarded from a LAN via a WAN connection that is taken care of automatically by the router.
GWAN = Gigabit WAN WAN = Wide Area Network LAN = Local Area Network WLAN = Wireless Local Area Network MAN = Metropolitan Area Network
Extranets are an add-on to an exiting company network, where as a WAN is any network that exceeds 2 kilometres squared (2 KM^2)
PSTN stands for Public switched telephone network PSDN stands for Public switched Data network / Packet Switched Data Network. The basic difference between two is the switching technique used. PSTN uses Circuit Switching and PSDN uses Packet Switching
