About these units
Kilobit (kb)
A kilobit represents 1,000 bits (decimal), commonly used in telecommunications and networking. Unlike computer storage, networking units generally favor decimal prefixes, making kilobits distinct from kibibits (1024-bit units). Kilobits are often used to express low-bandwidth data rates—such as early dial-up Internet speeds (e.g., 56 kbps), small sensor networks, or radio telemetry. Though kilobits appear small today, many communication systems still operate efficiently at kilobit speeds, especially low-power IoT devices designed for long battery life and minimal bandwidth usage.
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.
