Windows Device Manager, Plug and Play

With the advent of plug and play technology, hardware installation is almost like snap of fingers. Windows do it by automatically allocating resources for the device, see below resources allocation:

1. Interrupt request (IRQ) line numbers.
2. Direct memory access (DMA) channels
3. Input/output (I/O) port addresses
4. Memory address ranges

These are all available in the device manager> device properties > Resources tab.
Every resource must be unique for every device.
















If no conflict windows will use its default windows drivers and your plug and play device is ready to go.
