About Terabits

A terabit (Tbit) = 10¹² bits (SI). Submarine cable capacity: 2Africa cable (2024) designed at 180 Tbit/s; MAREA (2017) at 160 Tbit/s. Data-centre interconnects use 400 Gbit/s (0.4 Tbit/s) per link. PCIe 6.0 ×16 delivers ≈0.5 Tbit/s aggregate. NVMe RAID arrays with 100+ PCIe 5.0 SSDs approach 1 Tbit/s aggregate sequential read. 1 Tbit = 10¹² bits = 125 GB.

About Gigabits

A gigabit (Gbit) = 10⁹ bits (SI). 1 Gbit/s Ethernet (1000BASE-T) is the enterprise baseline; 10/25/100/400 Gbit/s are data-centre standards. Bus speeds: PCIe 4.0 ×16 = 256 Gbit/s; Thunderbolt 4 = 40 Gbit/s; HDMI 2.1 = 48 Gbit/s. NVMe SSDs: PCIe 4 ≈ 57 Gbit/s; PCIe 5 > 112 Gbit/s. Submarine cables: 200 Gbit/s per wavelength × hundreds of wavelengths. 1 Gbit = 10⁹ bits = 125 MB.
