Frequently Asked Questions
Why are there 8 bits in a byte?
The 8-bit byte became standard because it can represent 256 values (2^8), enough for all ASCII characters. IBM popularized it in the 1960s.
What is the difference between KB and KiB?
KB (kilobyte) = 1,000 bytes (SI standard). KiB (kibibyte) = 1,024 bytes (binary). Windows uses KiB but labels it KB, causing confusion.
How many bytes in a gigabyte?
There are 1,000,000,000 bytes (10^9) in 1 GB (SI standard), or 1,073,741,824 bytes in 1 GiB (binary).
