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 Gibibytes
A gibibyte (GiB) = 2³⁰ = 1,073,741,824 bytes (IEC 80000-13). The source of the 'storage discrepancy': a '500 GB' drive contains 500×10⁹ bytes ≈ 465.66 GiB as shown by Windows. RAM is manufactured in exact powers of 2: 4/8/16/32/64 GiB. GPU VRAM: RTX 4090 = 24 GiB; H100 = 80 GiB; MI300X = 192 GiB HBM3. Kubernetes memory limits use Gi suffixes. 1 GiB = 2³⁰ bytes = 1,024 MiB.
