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.
Quadruple-Word (quad-word)
A quadruple word (quad-word) is a grouping of four standard words. On a 64-bit system, this equals 256 bits, forming the basis of advanced operations such as wide integer arithmetic, extended SIMD instructions, cryptographic keys, and high-precision floating-point values. Modern CPUs support quad-word operations through SIMD extensions like AVX and AVX-512, allowing parallel processing of large blocks of data in scientific computing, video encoding, machine learning, and physics simulations. Quad-words illustrate how data grouping evolves with hardware capability: as processors grow more powerful, software increasingly relies on larger and more complex data units.
