What does IDE (PIO mode 3) mean in data transfer?

IDE (PIO mode 3) is a CPU-driven transfer mode for Parallel ATA/IDE devices with a theoretical maximum throughput of about 11.1 MB/s.

What is Fast Ethernet?

Fast Ethernet refers to IEEE 802.3 standards providing a nominal data rate of 100 Mbit/s, commonly used in local-area networking.

Why might actual data transfer speeds differ from the converted values?

Real speeds may differ due to hardware limits, protocol overhead, CPU-driven transfer mode limitations in IDE, and environmental conditions.
