why we can download faster with IDM

Solution

Without a download accelerator, you may not be hitting your and the remote server's bandwidth bottleneck. This means that either or both of you have still more bandwidth that can be tapped.

Download accelerators tap this extra bandwidth in two ways:

- By increasing the number of connections to the server, IDM consumes all or maximum of your bandwidth and increases the proportion of your total internet bandwidth that goes to the download.

- The remote server divides it's total bandwidth to the number of connections to it. So, multiple connections to the server ensure that the total bandwidth you're tapping is a sum of those divided bandwidths thus removing another bottleneck.

See http://en.wikipedia.org/wiki/Download_manager#Download_acceleration for more.

Problem

I have a question about downloading with IDM or without it the question is, we have the same bandwidth and the server sharing same bandwidth for IDM and simple downlaod manager. but why we can download faster with IDM? what is the reason? TNX...
