State-based system

A state-based system is a way of designing software that keeps track of its current condition or status at all times. Think of it like a digital "memory" that records where the system is in its process, allowing it to respond appropriately to inputs or changes. For example, a traffic light system uses different states—green, yellow, red—to control vehicle flow. In software, this approach helps manage complex behaviors by defining specific states and rules for moving between them, making systems more predictable, organized, and easier to troubleshoot.
