About these units
Bit (b)
A bit is the most fundamental unit of digital information, representing a binary value of 0 or 1. In physical systems, a bit corresponds to two distinguishable states—such as high/low voltage, magnetic polarity, or light/dark in optical systems. Bits form the basis of all digital computation: CPUs manipulate bits through logic gates, memory stores bits in capacitors or magnetic cells, and communication networks transmit bits as electrical pulses or photons. Although extremely small in size, bits accumulate into vast structures—from kilobytes of text to petabytes of cloud storage. Every digital phenomenon—files, images, videos, software—ultimately reduces to sequences of bits. The bit is the "atom" of information.
Nibble (nibble)
A nibble consists of 4 bits, exactly half of a byte. It is the smallest unit that can represent a single hexadecimal digit (0–F), which makes it essential in low-level data representation. Nibble operations arise in microcontroller design, bitwise arithmetic, encryption algorithms, and early computing architectures that manipulated data in 4-bit chunks. Although modern systems process much larger word sizes, nibbles remain conceptually important: digital logic circuits still group bits in fours for hexadecimal notation, instruction encoding, and debugging tasks. In many ways, the nibble serves as the bridge between binary and human-readable representations of digital information.
