About these units

Byte (B)

A byte consists of 8 bits, forming the standard grouping used in computing for representing characters, numbers, and machine instructions. This 8-bit size became dominant due to hardware design choices in early microprocessors, especially the IBM System/360 architecture. Bytes allow computers to represent values from 0 to 255, enabling ASCII encoding, color values, file metadata, and vast amounts of structured data. The byte is the basis for nearly all storage units—kilobytes, megabytes, gigabytes—and remains the fundamental digital "counting unit" for memory, disk space, and network transfers.

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.
