About Kibibytes

A kibibyte (KiB) = 2¹⁰ = 1,024 bytes (IEC 80000-13) - the binary kilobyte used by OS memory management. Linux/Windows page size = 4 KiB (4,096 bytes); default NTFS/ext4/APFS cluster size = 4 KiB. CPU L1-D cache: 16-64 KiB. Arduino AVR flash: 2-32 KiB. Windows labels KiB as 'KB'. 1 KiB = 1,024 bytes = 8,192 bits.

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.
