About Bits
The bit (b) is the fundamental unit of digital information - a single binary digit: 0 or 1. Coined by John Tukey in 1948; formalised by Claude Shannon. Physically realised as transistor states (SRAM/DRAM), magnetic domains (HDD), charge levels in NAND flash (MLC=2, TLC=3, QLC=4 bits per cell). Shannon entropy: a coin flip = 1 bit; a card drawn from a 52-card deck ≈ 5.7 bits. 1 bit = 1/4 nibble = 1/8 byte.
About Zebibits
A zebibit (Zibit) = 2⁷⁰ bits ≈ 1.18 × 10²¹ bits (IEC 80000-13). Total world manufactured digital storage in 2023 (≈ 10,000 EB ≈ 80,000 Ebit) is ≈ 67,000× smaller than 1 Zibit. A 70-bit byte address space would address 2⁷⁰ bytes = 128 ZiB of memory - far beyond any foreseeable architecture. At projected HDD areal density (10¹² bits/cm²), 1 Zibit would require ≈ 10⁹ cm² ≈ the area of Iceland. 1 Zibit = 2⁷⁰ bits = 128 EiB.
