Networking: LAN vs WAN

I have a basic question about networking.

What is the difference between LAN vs WAN in terms of usage?

I have a server/client application which connect through TCP. I have tried it between computers connected in the same LAN and was able to connect with each other using the computer name / ip address.

Will the same application work if the computers are connected through WAN?

Thanks for the link.

According to my client, the computers are connected through WAN and they "see" each other. Can I assume that it will work like they are connected through LAN but with a lower transfer rate?

Thomsaian,

You can ask your client to do a simple ping test to check connectivity and telnet to the application port number to check for firewall rules.
I see, so does that mean that if the ping test works and the port is not blocked, then the application would work just like they are connected through LAN?
