About these units
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.
Block (block)
A block is a unit of data storage used by file systems, typically ranging from 512 bytes to 4096 bytes, though advanced systems may use even larger sizes (8 KB, 16 KB, etc.). Blocks form the fundamental allocation unit for disk storage—files occupy blocks on disk, and file systems track which blocks belong to which files. Block size has significant performance implications. Larger blocks improve read/write throughput but may waste space for small files (internal fragmentation). Smaller blocks offer precision but reduce I/O efficiency. Many classic file systems (FAT, ext2), modern ones (ext4, NTFS), and network storage systems (ZFS, Btrfs, distributed file systems) all rely on block-based allocation. Blocks bridge the gap between raw physical storage and abstract file structures.
