Open calculator →Measured storage rather than label capacity
The first Computing group distinguishes usable capacity, current use, reserved space, logical file size, allocated blocks, metadata, and temporary workspace. Each quantity stays attached to its source unit and observation boundary.
Files, allocation, and compression
Collection, average-file, duplicate, manifest, cluster, inode, sparse-file, compression, archive, multipart, and chunk tools turn recorded counts and sizes into checkable totals. They avoid predicting how an unmeasured dataset will compress or how a filesystem will allocate content.
Backups, snapshots, and retained copies
Full, incremental, GFS, snapshot, deduplication, replication, metadata, and erasure-coding pages total the policies entered by the user. A calculated capacity is not evidence that a backup is recoverable, immutable, secure, or correctly configured.
Throughput, migration, and verification
Archive, hashing, erasure, and migration estimates begin with observed throughput and keep allowances visible. Verification sampling is presented as arithmetic only and does not claim statistical assurance.
Networking measurements and address capacity
Transfer, throughput, latency, packet, cache, data-use, API, WiFi, and IP-prefix pages use values supplied by the visitor. They distinguish bits from bytes, preserve measurement direction and time windows, and avoid claiming knowledge of a live provider, route, device, or policy.
Planned Computing groups
The remaining blueprint groups cover Displays and Graphics, Performance and Capacity, and Web and Development. They will be published only after their formulas, content patterns, links, and rendered behavior pass the same batch audit.
