What does IDE (DMA mode 1) mean?

IDE (DMA mode 1) is a Direct Memory Access mode in the IDE/ATA interface that allows data transfers with minimal CPU involvement, set for moderate speed according to legacy hardware protocols.

What is modem (2400)?

Modem (2400) indicates a modem data rate of 2400 bits per second, typical for early dial-up modems like ITU-T V.22bis standards.

Why convert between IDE (DMA mode 1) and modem (2400)?

Converting between these units helps compare legacy storage transfer speeds to classic modem communication rates, useful for diagnostics, testing, and historical research.
