About Megabits

A megabit (Mbit) = 1,000,000 bits (SI). Everyday unit for broadband speeds: ADSL2+ up to 24 Mbit/s; VDSL2 up to 100 Mbit/s; GPON fibre 100-10,000 Mbit/s; 5G NR 100-400 Mbit/s. Streaming: Netflix 1080p = 5 Mbit/s; 4K HDR = 15-25 Mbit/s. Wi-Fi 7 = 46,120 Mbit/s theoretical. ISP 'Mbps' = megabits/s; 'MB/s' (megabytes) is 8× larger. 1 Mbit = 1,000,000 bits = 125,000 bytes.

About Gibibytes

A gibibyte (GiB) = 2³⁰ = 1,073,741,824 bytes (IEC 80000-13). The source of the 'storage discrepancy': a '500 GB' drive contains 500×10⁹ bytes ≈ 465.66 GiB as shown by Windows. RAM is manufactured in exact powers of 2: 4/8/16/32/64 GiB. GPU VRAM: RTX 4090 = 24 GiB; H100 = 80 GiB; MI300X = 192 GiB HBM3. Kubernetes memory limits use Gi suffixes. 1 GiB = 2³⁰ bytes = 1,024 MiB.
