What is Backend?
The behind-the-scenes part of an application that handles data, logic, and communication with databases
Why It Matters
The backend is where business logic lives, processing orders, managing user accounts, and keeping data secure
Real-World Example
When you submit an order, the backend validates it, charges your card, and updates the inventory
“Understanding terms like Backend matters because it helps you have better conversations with developers and make smarter decisions about your software. You do not need to be technical. You just need to know enough to ask the right questions.”
