Digital Storage Fundamentals
Digital storage units are used to measure data capacity in computing and digital systems. The basic unit is the bit (b), which represents a single binary value (0 or 1). Eight bits make up one byte (B), which is typically the smallest addressable unit of memory in most computer architectures. As technology has evolved, we've needed larger units to describe growing storage capacities, leading to two parallel systems: the decimal (SI) system using powers of 1000, and the binary system using powers of 1024.
Binary vs. Decimal Units
| Size | Decimal (SI) | Binary (IEC) | Difference |
|---|---|---|---|
| Kilo/Kibi | 1000 (KB) | 1024 (KiB) | 2.4% |
| Mega/Mebi | 1000² (MB) | 1024² (MiB) | 4.9% |
| Giga/Gibi | 1000³ (GB) | 1024³ (GiB) | 7.4% |
| Tera/Tebi | 1000⁴ (TB) | 1024⁴ (TiB) | 10.0% |
| Peta/Pebi | 1000⁵ (PB) | 1024⁵ (PiB) | 12.6% |
| Exa/Exbi | 1000⁶ (EB) | 1024⁶ (EiB) | 15.3% |
| Zetta/Zebi | 1000⁷ (ZB) | 1024⁷ (ZiB) | 18.4% |
