A system is like a big puzzle that has different parts that work together to help it do something. Imagine you have a toy car with wheels, a motor, and a remote control. When you put all the parts together, you can make the car move around by using the remote control. This is a simple example of a system.
In real life, systems can be much more complicated than a toy car. There are many different types of systems, like computer systems, transportation systems, or even your body! These systems can have lots of different parts that work together to help them do their job.
For example, a computer system might have parts like the monitor, keyboard, and mouse that all work together to let you use the computer. Transportation systems like a bus system have different parts like the bus, the driver, and the routes that they follow to get people from one place to another.
So, when we talk about a system, we are talking about something that has many different parts that work together to help it do something. The parts of a system are like puzzle pieces, and when they fit together just right, the system can do its job!
