What are software systems?

A software system is like a special kind of robot that helps us do things on computers, phones, or even smart toys.

Imagine you have a toy car that moves when you press a button. That button is like the input, and the car moving is the output. A software system is like the brain inside the toy car, it tells the wheels to move when you press the button.

Think of a software system as a team of workers in a big factory. Each worker has their own job:

• One worker gets your order (like pressing a button).
• Another worker prepares the parts.
• A third worker sends everything off to be finished and ready for you.

These workers all talk to each other using messages, just like how people in a kitchen might shout orders back and forth. The whole factory works together so that when you press the button, your toy car zooms off!

Software systems can be simple, like a calculator, or really big, like a video game with lots of characters and levels. But they all do their job by following rules and talking to each other.
