About Data Units
Bit (b) - The smallest unit of data in computing, representing a single binary value of 0 or 1.
Byte (B) - A group of 8 bits. The basic unit used to represent a single character of text in most computer systems.
Binary vs. Decimal Units - Two standards are used for measuring data:
- Binary (IEC Standard): Based on powers of 2. Units are named kibibyte (KiB), mebibyte (MiB), etc. 1 KiB = 1,024 bytes.
- Decimal (SI Standard): Based on powers of 10. Units are named kilobyte (KB), megabyte (MB), etc. 1 KB = 1,000 bytes.
Common Misconceptions - Storage device manufacturers typically use decimal units (1 TB = 1,000,000,000,000 bytes), while operating systems often report in binary units (1 TiB = 1,099,511,627,776 bytes). This difference explains why a "1 TB" hard drive shows less space in your computer.
