About Bytes

The byte (B) is the fundamental addressable memory unit - 8 bits, 256 values (0-255). Standardised by the IBM System/360 (1964). UTF-8 encodes ASCII in 1 byte; Unicode in 1-4 bytes. One byte = 1 ASCII character, 1 RGB channel value, 1 PCM audio sample (8-bit). All mainstream CPU architectures (x86-64, ARM64, RISC-V) increment addresses by 1 byte. 1 byte = 8 bits = 2 nibbles.

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.
