What is IDE (UDMA mode 4)?

IDE (UDMA mode 4) is a Parallel ATA transfer mode, also known as Ultra DMA/66, used in older PCs to move data between drives and hosts at up to about 66.7 megabytes per second.

What does STS48 (signal) represent?

STS48 is a SONET signal equivalent to OC-48, providing a synchronous transport rate of approximately 2.48832 gigabits per second used in high-capacity optical telecommunications.

Can I use this converter for direct data transfer between devices?

No, this converter provides theoretical bandwidth equivalences and comparisons, not direct compatibility or data transfer between differing protocols and physical media.
