About Kibibits

A kibibit (Kibit) = 2¹⁰ = 1,024 bits (IEC 80000-13) - the binary counterpart to the kilobit. Defined to eliminate ambiguity between 1,000-bit and 1,024-bit 'kilobits'. Used in FPGA/ASIC block RAM sizing (a 32 Kibit block RAM = 4,096 bytes) and JEDEC DRAM specs. RSA key lengths (e.g. '4096-bit') are exact counts, unaffected by the kib/kb distinction. 1 Kibit = 1,024 bits = 128 bytes.

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.
