About Petabits

A petabit (Pbit) = 10¹⁵ bits (SI). Major internet exchange points (DE-CIX, AMS-IX) handle peak traffic of multi-Tbit/s, accumulating Pbits per hour. Bell Labs (2022) achieved 1.02 Pbit/s over a single fibre pair. CERN LHC distributes ≈ 720 Pbit/year through the WLCG computing grid. 100 wavelengths at 800 Gbit/s each = 80 Tbit/s per fibre; ≈13 such fibres = 1 Pbit/s. 1 Pbit = 10¹⁵ bits = 125 TB.

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.
