What is IDE (DMA mode 0)?

IDE (DMA mode 0) is the first and slowest direct memory access transfer mode for ATA/IDE devices, allowing data blocks to move to system memory without CPU involvement.

What does OC1 represent?

OC1, or Optical Carrier level 1, is the base SONET optical transmission rate at 51.84 Mbit/s, used as a fundamental building block for higher-capacity optical networking.

Why convert between IDE (DMA mode 0) and OC1?

Converting between these units helps compare legacy data transfer capabilities with modern optical speeds, assisting in diagnostics, system design, and network planning.
