Bit
A bit (b) is the smallest unit of digital information. It represents a binary value of 0 or 1, the foundation of all data processing in computers and electronic systems. Bits are most commonly used to measure internet speeds, network bandwidth, and data transmission rates.
Because bits are so small, they scale up into larger units like kilobits and megabits for practical use. Converters help users translate network speed ratings into file sizes to understand how long downloads or streaming might take.
Byte
A byte (B) is a standard unit of digital data equal to 8 bits. It represents a single text character or a small chunk of a file. Bytes are used to measure storage capacity in everything from documents to photos and software applications.
Since bytes scale cleanly into larger units like kilobytes and megabytes, they provide a practical base for understanding how much data a device holds. Converters help translate between bytes and bits when moving between storage and speed contexts.
