Conversation

I was reading about how different computer systems have their own subsystem for managing tasks.

Oh really? That sounds interesting!

Yeah, each subsystem can work independently but still communicate with the main system.

That makes sense; it must help improve efficiency overall.

Root Explanation

Subsystem → It is formed from "sub-" (meaning under or below) and "system" (from Greek "sustema", meaning a whole made up of parts). The word "subsystem" refers to a smaller system that is part of a larger system, functioning under it.

Memory Tip

Think of a smaller system that operates 'under' ('sub-') a larger whole ('system'). This helps you remember that a subsystem is a part of a bigger system.
