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 Exbibytes
An exbibyte (EiB) = 2⁶³ bytes ≈ 9.22 × 10¹⁸ bytes (IEC 80000-13). 2⁶³ is also the absolute value of INT64_MIN (the smallest signed 64-bit integer), making 1 EiB the natural upper limit for file systems using signed 64-bit byte offsets. File system theoretical maxima: NTFS 16 EiB; APFS 8 EiB; Btrfs 16 EiB; ZFS 256 quadrillion ZiB. Total hyperscale cloud storage estimated at 500-1,000 EiB as of 2024. 1 EiB = 2⁶⁰ bytes = 1,024 PiB.
