What does IDE (PIO mode 2) represent?

It is a legacy CPU-controlled data transfer timing mode used in older ATA/IDE drives defining how data is moved through programmed input/output cycles.

What is OC3 used for?

OC3 is an optical transmission rate used in synchronous optical networking, typically for backbone links and long-distance fiber transport.

Can this converter be used for real-time performance measurement?

No, the conversion is an approximation and does not account for network overhead or protocol differences, so it is not suitable for precise performance metrics.
