Add-ins
              An add-in is a software component that increases the functionality of larger programs. It is a term frequently
              used by Microsoft and other platforms that allow for the addition of extra features to core programs. An add-
              in has specific, limited features that consume less memory. An add-in is installed separately and cannot be
              used independently. Once installed, the add-in merges with the main software. For example, Microsoft Excel
              uses a lot of add-ins for a variety of purposes.

              SNIPPET

              A "snippet" is a small, reusable piece of code that can be integrated into a larger code base. Developers talk about
              snippets with specific functionality, and how snippets can be implemented when building larger, more complex programs.
              Snippets have several uses. Some snippets of text editors and other software programs manage specific document
              processing tasks. Some snippets can be integrated into programs such as Visual Studio and reused in projects running
              within that platform.
