🔹 What is a System?

A system is a group of interconnected parts or components that work together in an organized way to perform a task or achieve a specific goal.

In simple words, a system is not just a single thing, but a combination of many things working together to do something useful.

 

🔸 Explanation in Simple Terms:

• Think of your body. It is a system.
• Your body has different parts: heart, lungs, brain, stomach, etc.
• Each part does a different job, but they all work together to keep you alive.
• If one part stops working, it affects the whole system.
• That’s how a system works – each part has a role, and together they achieve a common purpose.

 

🔹 Formal Definition of a System:

A system is a set of interrelated components or elements that are organized to achieve a specific objective by accepting inputs, processing them, and producing outputs.

🔸 Key Features of a System:

1. Components – Different parts that make up the system.
2. Interdependence – The components depend on each other.
3. Interaction – The components communicate or exchange data/materials.
4. Goal/Purpose – The system is designed to do something useful.
5. Input and Output – Systems take something in (input), do something to it (process), and give something out (output).
6. Processing – The transformation that happens inside the system.
7. Feedback – Information returned to improve or control the system.
