What does USB stand for and what is its purpose?

USB stands for Universal Serial Bus, a standard interface for data communication and power delivery between hosts like computers and peripheral devices.

What is IDE (PIO mode 2) used for?

IDE (PIO mode 2) is a legacy ATA/IDE timing specification for CPU-driven data transfers with older IDE drives, used mainly in vintage PC configurations and diagnostics.

Can I use this converter for precise transfer rate measurements?

No, this tool gives approximate conversions since USB speeds vary by generation and IDE (PIO mode 2) is a fixed legacy mode with different performance characteristics.
