Dear Sue,
I heard about VoIP(Voice over Internet Protocol) a few days ago. This technology is very common in the US and your sun is very familiar to it.
VoIP works on a network. When we use it, we can talk each other through Internet an satellites and nobody can hear our words.
For instance, you have several offices in several countries. If you use VoIP, you can dial just 2 or 3 numbers to connect to other office phones like a internal telephone network of a company.
It is just a usage of VoIP and It is used in many cases.
I said to you network is very young in Iran so VoIP isn't common here now.
I have a thesis next term. I really like to do a new and special things in this field but I don't know what I can do. It makes my mind busy.
In the US, you do most things on a network that I don't know most of them. I thank you a lot if you help me about it.
Your friend, Faranak.
