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.
Gigabyte (GB)
A gigabyte is 1,073,741,824 bytes (2³⁰) in binary notation, or 1,000,000,000 bytes in decimal form. Gigabytes serve as one of the most common units of modern computing: RAM capacities, smartphone storage, software downloads, and video file sizes frequently range from a few GB to dozens of gigabytes. The gigabyte era represented a massive shift in capability—allowing high-resolution multimedia, complex software, virtual machines, and databases to flourish. While once enormous, gigabytes are now considered routine, illustrating the exponential growth of digital storage.
