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 Nibbles

A nibble is exactly 4 bits = half a byte, representing 2⁴ = 16 values - one hexadecimal digit (0-F). Used in BCD encoding (each decimal digit = 1 nibble; 2 nibbles per byte packs two BCD digits), financial/mainframe packed-decimal formats, and CSS hex colours (#RRGGBB = 2 nibbles per channel). 4-bit processors (Intel 4004, TI TMS1000) processed one nibble per cycle. 1 nibble = 4 bits = 0.5 bytes.
