📖 Data Storage Unit Guide
Digital storage is measured in bytes and their multiples. There are two standards: the decimal (SI) system used by hard drive manufacturers (1 KB = 1,000 bytes), and the binary (IEC) system used by operating systems (1 KiB = 1,024 bytes). This difference explains why a "500 GB" hard drive shows as ~465 GB in Windows.
