FAQ
kB vs KiB — what’s the difference?
kB is decimal (1000 bytes). KiB is binary (1024 bytes). Likewise MB vs MiB, GB vs GiB, etc.
Bit vs byte?
1 byte = 8 bits. Network speeds are often in bits/s, while file sizes are in bytes.
Why do disks show less capacity than advertised?
Manufacturers use decimal GB (1 GB = 1,000,000,000 B). Operating systems often display binary GiB (1 GiB = 1,073,741,824 B), so numbers look smaller.
