ITPEC IP October 2021 Question 17
ITPEC IP October 2021 — Question 17 of 100
Plug-in software is integrated into a host application to extend its functions and normally does not operate as a standalone program. A browser plug-in, for example, adds a capability that the browser exposes through its extension interface.
Answer (b)
Why not others:
- software that bridges differences between operating systems is a compatibility or middleware layer
- recording and replaying spreadsheet operations describes a macro
- code supplied to replace part of a program and fix defects describes a patch
Key rule: A plug-in depends on a host application and adds functionality through an interface provided by that host.
