About Terabits per second
Terabit per second (Tbit/s) = 10¹² bit/s (SI). Internet backbone scale: MAREA cable (2017) = 200 Tbit/s per fibre pair; 2Africa cable (2024) = 180 Tbit/s. DWDM: 100 wavelengths × 800 Gbit/s = 80 Tbit/s per fibre. H100 GPU HBM3 memory bandwidth = 3.35 Tbit/s per GPU. NTT lab record (2023): 1,200 Tbit/s over a single fibre. 1 Tbit/s = 10¹² bit/s = 125 GB/s.
About Kilobytes per second
Kilobyte per second (KB/s) = 1,000 B/s = 8,000 bit/s (SI). Legacy modem throughput: 56 kbit/s dial-up ≈ 7 KB/s; ISDN 128 kbit/s = 16 KB/s. RS-232 at 115,200 baud (8N1) = 11.52 KB/s. CD-ROM 1× = 150 KB/s; 52× = 7,800 KB/s. Bluetooth 2.1 EDR ≈ 300 KB/s; USB 1.1 Full Speed = 1,500 KB/s. 1 KB/s = 1,000 B/s = 8 kbit/s.
