About Gigabytes
A gigabyte (GB) = 10⁹ bytes (SI). All consumer HDDs, SSDs, SD cards, USB drives, and smartphones advertise in GB. Media sizes: 4K Blu-ray 66-100 GB; 4K Netflix film 10-15 GB; modern AAA PC game 50-200 GB; Google Maps offline country data 5-30 GB.

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.
