Patch (computing)
piece of software designed to update a computer program to fix or improve it
A patch is data for modifying an existing software resource such as a program or a file, often to fix bugs and security vulnerabilities. To patch is also the process of applying the data to the existing resource. Patching a system involves applying a patch. A patch may be created to improve functionality, usability, or performance. A patch may be created manually, but commonly it is created via a tool that compares two versions of the resource and generates data that can be used to transform one to the other.
Typically, a patch needs to be applied to the specific version of the resource it is intended to modify, although there are exceptions. Some patching tools can detect the version of the existing resource and apply the appropriate patch, even if it supports multiple versions. As more patches are released, their cumulative size can grow significantly, sometimes exceeding the size of the resource itself. To manage this, the number of supported versions may be limited, or a complete copy of the resource might be provided instead.
Patching allows for modifying a binary executable.
The public source identifies “Patch (computing)” as piece of software designed to update a computer program to fix or improve it. This brief keeps that definition visible, then builds a research path around Patch, computing and piece.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Patch (computing)”, the useful work is to connect “piece of software designed to update a computer program to fix or improve it” to the records capable of establishing context and consequence.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Apr 16, 2026. The linked authority identifier is Q208218.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
