Data Storage Unit Knowledge
Data Unit Basics
Digital data is stored and measured in bits and bytes. A bit (binary digit) is the smallest unit of data (0 or 1). A byte consists of 8 bits and can represent 256 different values.
Decimal vs Binary Prefixes
- Two systems exist: decimal (SI) uses powers of 1000 (KB = 1,000 bytes), while binary (IEC) uses powers of 1024 (KiB = 1,024 bytes). Hard drive manufacturers use decimal
- operating systems often use binary. This causes apparent size discrepancies.
Common Storage Sizes
- 1 KB = 1,000 bytes (decimal) or 1,024 bytes (binary)
- 1 MB = 1,000,000 bytes
- 1 GB = 1,000,000,000 bytes
- 1 TB = 1,000,000,000,000 bytes. A typical smartphone has 128 GB–1 TB storage.
Data Transmission
Network speeds are measured in bits per second (bps). 1 Mbps = 1,000,000 bits/s. To download a 1 GB file at 100 Mbps: 1 GB = 8 Gb, so 8,000 Mb / 100 Mbps = 80 seconds.
IEC Binary Units
The IEC introduced binary prefixes to avoid confusion: kibibyte (KiB) = 1,024 bytes, mebibyte (MiB) = 1,048,576 bytes, gibibyte (GiB) = 1,073,741,824 bytes, tebibyte (TiB) = 1,099,511,627,776 bytes.
