What does IDE (PIO mode 2) represent?

It is a legacy ATA/IDE interface timing specification defining CPU-driven data transfer timing for older storage devices using programmed input/output cycles.

What is the significance of T4 (signal)?

T4 (signal) is a high-order trunk in the North American T-carrier telecom hierarchy, representing a multiplexed signal rate used primarily for long-distance backbone links before modern network technologies.

Can I use this converter to measure real-time data transfers?

No, since IDE (PIO mode 2) and T4 (signal) belong to different technological contexts, this tool is meant for theoretical comparisons rather than direct real-time data measurement.
