What does USB stand for and what is it used for?

USB stands for Universal Serial Bus and is a standard for data communication and power delivery between host devices like computers and peripherals such as flash drives and keyboards.

What is IDE (PIO mode 1) used for?

IDE (PIO mode 1) is a CPU-controlled data transfer mode used with legacy PATA devices, typically for configuring, diagnosing, or benchmarking older hard drives and optical drives.

Can I use this conversion for direct hardware communication?

No, the conversion is theoretical and used mainly for comparing or adapting data transfer rates; direct interoperation between USB and IDE (PIO mode 1) hardware is not possible.
