About these units
Nibble (nibble)
A nibble consists of 4 bits, exactly half of a byte. It is the smallest unit that can represent a single hexadecimal digit (0–F), which makes it essential in low-level data representation. Nibble operations arise in microcontroller design, bitwise arithmetic, encryption algorithms, and early computing architectures that manipulated data in 4-bit chunks. Although modern systems process much larger word sizes, nibbles remain conceptually important: digital logic circuits still group bits in fours for hexadecimal notation, instruction encoding, and debugging tasks. In many ways, the nibble serves as the bridge between binary and human-readable representations of digital information.
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.
