| Workflow | The process of organising business processes as a controlled sequence of activities. |
| WORM | Storage. Write Once Read Many |
| Write Precompensation | Storage products. With the change of the speed of the disk relative to the head (changes from track to track due to varying disk diameter), the data bit also travels within the read window margin. In order that this does not lead to read errors, the write data are shifted in time. This is done starting with a specific track.

| Yellow Book | A CD-ROM format which is ISO 9660 compliant and uses mode 1 addressing. Discs of this type can be played on most drives and would be appropriate for most multimedia applications which have been developed for personal computers. |
| Yottabyte (YB) | This is 2^80 bytes, or 1024 zettabytes. |
| Zettabyte (ZB) | This is 2^70 bytes, or 1024 exabytes. |
| Zoning | The process of allocating resources in a SAN to load balance the devices connected to the network. Zoning allows the network administrator to separate the SAN into units and allocate storage to those units based on need. Zoning protects the SAN system from such threats as viruses, data corruption and malicious hackers as the devices in their respective zones are not able to communicate outside the zone through their ports unless given permission. |
