blockhantering

Blockhantering, or block handling, refers to the management of blocks—the fixed-size units used to organize data or physical material. It covers how blocks are allocated, tracked, moved, stored, and retrieved, with the aim of efficient space use, performance, and safety.

In information technology, block handling applies to block storage devices and filesystems. Block devices present raw blocks to the operating system, and the filesystem maps files to blocks while managing allocation, free space, and metadata. Key concepts include block size, allocation strategies (contiguous, linked, extents), fragmentation, caching, and I/O scheduling. Effective block management influences access speed, storage efficiency, and data integrity. Tools such as logical volume managers, RAID configurations, and advanced filesystems implement block handling to optimize reads and writes.

In logistics and manufacturing, block handling describes moving and storing blocks or pallets in warehouses. It encompasses receiving, labeling, stacking, routing, and retrieval, using equipment like forklifts, cranes, and conveyors. Proper block handling improves inventory accuracy, safety, and throughput and is often integrated with warehouse management systems.

Common considerations across contexts include fragmentation or fragmentation-like inefficiencies, synchronization in multi-user environments, and maintaining data integrity or physical safety when blocks are moved. The term thus spans both digital and physical domains, representing the broader discipline of organizing and controlling fixed-size blocks to maximize efficiency and reliability.
