What does IDE (UDMA mode 4) refer to?

IDE (UDMA mode 4) is a Parallel ATA transfer mode using the Ultra DMA protocol, with a maximum theoretical throughput of about 66.7 megabytes per second, typically requiring an 80-conductor IDE cable.

How is ISDN (dual channel) defined?

ISDN (dual channel) uses both 64 kbit/s B channels of an ISDN Basic Rate Interface in parallel to provide about 128 kbit/s combined throughput.

Why convert between IDE (UDMA mode 4) and ISDN (dual channel)?

Converting between these units helps compare data transfer capacities and assists in planning data migration, backup, or networking involving legacy storage and telecommunication systems.

How to Convert from IDE (UDMA mode 4) to ISDN (dual channel)?
