A block is a fixed-size unit of data storage and retrieval, typically consisting of multiple bytes or items handled as a single entity. Files are stored as sequences of blocks on disk, and read/write operations often transfer entire blocks for efficiency rather than individual items. Block sizes vary by system but are commonly 512 bytes, 1KB, or 4KB.
