About these units
Gigabit (Gb)
A gigabit is 1,000,000,000 bits, commonly used to describe modern network speeds, such as 1 Gbps Ethernet, fiber-optic connections, and high-speed wireless systems. Gigabit connections revolutionized both home and enterprise computing by enabling rapid file transfers, cloud computing, and high-definition streaming. As speeds continue to increase—10, 40, 100 Gbps and beyond—the gigabit becomes a foundational stepping stone in the evolution of networking capability. The Gb illustrates how rapidly communication technology has scaled compared to physical 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.
