Why do we need plugins?

Question

I understand the use of plugins, when used on search engine like google to for example read PDF or block ads etc
But why do we need plugin in an embedded system code?
is it for the same reason?

Answer 1

In embedded systems, plugins provide modularity, customization, and resource optimization. They enable feature expansion, reduce code size, support third-party integration, enhance testing, and aid in security isolation and system maintenance, making embedded systems more adaptable and efficient.
