What does IDE (DMA mode 0) mean?

IDE (DMA mode 0) is the earliest direct memory access transfer mode for ATA/IDE devices, enabling data blocks to move directly into system memory without CPU involvement.

What speeds does a 14.4k modem support?

A 14.4k modem can transmit data at up to 14.4 kilobits per second over analog telephone lines via modulation and demodulation techniques.

Why convert between IDE DMA and modem speeds?

Converting helps compare legacy hard drive interface speeds with dial-up modem rates for performance analysis or system compatibility in historical or embedded applications.
