What does Modem (2400) represent?

Modem (2400) denotes a modem data-transfer rate of 2400 bits per second, typical of early dial-up modem standards like ITU‑T V.22bis. It is a descriptive speed classification rather than an SI unit.

What is IDE (PIO mode 4)?

IDE (PIO mode 4) is a timing mode for ATA/IDE storage devices where the CPU controls data transfers, featuring a theoretical maximum throughput of about 16.7 MB/s. It characterizes transfer timing rather than storage volume.

Why convert between Modem (2400) and IDE (PIO mode 4)?

Converting these units helps compare legacy modem data rates with older CPU-driven storage interface speeds, useful for retro-computing, vintage diagnostics, and assessing hardware compatibility.
