Patch
In short and in plain language
A patch is a small fix for software. It closes a known error or security gap.
The vendor provides it. It only works once it has been applied to the shop.
While a patch is missing, a known weak spot stays open.

A patch is a small correction to software that fixes a known error or security gap. It is provided by the vendor and only takes effect once it has been applied to the shop. As long as a patch is missing, a known vulnerability stays open.
