Sir,
I want to develop a internet booster software that boost the speed of internet from original speed to high speed.please tell me how internet booster works and which language i should use?

Call your ISP and ask it how to increase your speed.

There is no such thing as "internet booster software". While there are many people selling things called that, in reality those things do nothing whatsoever.

At most a few might allow more efficient use of the bandwidth available to the machine, but most don't even do that, they just sit there giving visual clues as to how fast your connection now is that don't mean a thing because they're not based on anything at all.
IOW they're a fraud.

As such you can create them in any language whatsoever, as long as you know how to create fancy user interfaces with flashy graphics.
