Well, I suppose when topics get old, they are forgotten...
So I copy and paste my question from an older topic...Thanks for any help.

I have a relative question as I am seriously thinking of creating a web host service as a thesis project in a e-commerce course.

When we refer to bandwidth, I have the idea that it is the maximum data the line can handle in one specific instant second. Have I got it right? So, we can only have a theoretical approach to what the monthly transfer would be. And again the idea I have is that we can say that maximum transfer for this line is that data and that assumes that server uses all avaiolable bandwidth in every single second.

So, if I got both right, could I have some ideas of how much real traffic in GB, under normal conditions, a line of 512,1024,...etc mbits could handle per day or per month.

By the way, when a host says that has a connection of 155Mbits, should I usually expect it to be a leased line?

Yes. The providers charge the customer (the Webhost) for the guarantee of the bandwidth through their routers and for the cost of laying cable.

Connection speeds are referred to as the number of bits the connection can handle in the period of one second. For instance, a T1 is 1.55 megabits, which is 1,550,000 million binary digits every second.

Hope this helps.
