Patch
A small software update released to fix a problem or security weakness
What's it for?
Fixes a specific software problem or security weakness without replacing the whole product.
For example…
A critical security fix is installed on company laptops over the weekend.
A vendor releases a patch to fix a security flaw in the payroll application without changing the product's major version
Think of it like…
Sewing a tear in a jacket instead of buying a new wardrobe
