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.

About Kilobytes

A kilobyte (KB) = 1,000 bytes (SI). Used by all storage manufacturers (HDD, SSD, USB, SD) and endorsed by the IEC and FTC. Typical sizes: plain-text email 2-5 KB; HTML page 10-100 KB; Word document 10-30 KB. Ethernet MTU = 1,500 bytes ≈ 1.5 KB; jumbo frames 9 KB. MP3 at 128 kbit/s = 16 KB/s of audio. 1 KB = 1,000 bytes = 8,000 bits.
