What does modem (28.8k) represent?

It is an informal label for a data transfer rate of approximately 28.8 kilobits per second via a 28.8k dial-up modem over an analog telephone line.

What is IDE (UDMA mode 3)?

It is a Parallel ATA interface transfer mode providing a theoretical raw transfer rate around 44.4 MB/s using Ultra DMA mode 3, commonly referred to as UDMA/44.

Why convert between these two units?

Converting helps compare the data transfer capabilities of legacy analog modems with those of older PATA/IDE storage devices and facilitates understanding of historic hardware performance.
