How did technology, logistics, and communication allow the north to defeat the south?

It enabled them to wage a modern war

Explanation:

The Northern states supplied the military with all the means necessary to wage a modern war, producing large quantities of ammunition and other supplies, and in doing so financing the war with its industrial capacity. The Midwest supplied the Union with soldiers, food, horses as well as financially. Military hospitals were located throughout the territory of the Union.

The national banking system was reformed during this period, and prosperity was stimulated by heavy spending by the federal government. Union countries have invested a great deal of money and effort in psychological and social support for soldiers, their wives, widows and orphans.
