Think about your morning routine. If there is light (NEPA/PHCN), you might use the electric kettle. Else, you use the gas stove. It's a simple decision based on a condition.
In code, we use these to make the program 'smart.' If the user enters the right password, let them in. Else, show an error message. It's the logic of everyday life translated for a machine.
I always tell my students to write out their logic on paper first. If you can't explain the 'If-Else' in plain English, you'll struggle to code it. Keep it simple!
