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.

About Pebibits

A pebibit (Pibit) = 2⁵⁰ bits (IEC 80000-13). Intel LA57 5-level paging extends virtual addressing to 57 bits = 128 PiB = 1 Pibit of byte-addressable virtual memory space per process. The Frontier supercomputer (ORNL, 2022) has ≈700 PiB = 5,600 Pibit of total Lustre storage. AMD EPYC Milan-X supports up to 52-bit physical addresses (4 PiB). 1 Pibit = 2⁵⁰ bits = 128 TiB.
