What is Byte?

The byte is the fundamental unit of digital data, consisting of 8 bits. One byte is enough to represent a single ASCII character such as a letter or digit. In UTF-8 encoding, a Japanese character typically requires 3 bytes. All larger data units (KB, MB, GB, TB) are built upon the byte. It serves as the basic addressable unit in computer memory and storage systems.

What is Kilobyte?

The kilobyte is a unit of digital data equal to 1,000 bytes (one thousand bytes). Short text files, simple HTML pages, and plain-text emails typically measure just a few kilobytes. In the early history of computing, programs and games ran in kilobytes of memory, and the unit remains a symbol of efficient programming. Today, kilobytes are used for small configuration files, icons, and plain-text documents. This tool uses SI prefixes where 1 KB equals 1,000 bytes.
