What is a server — CCA-F Exam Prep

A vending machine vs. a store clerk.

Both give you things. You make a selection, you get a product.

But the vending machine works 24/7. Never takes a break. Never improvises. You press B7, you get B7. You press a button that doesn't exist, you get nothing. No negotiation. No exceptions.

That's a server. Always on. Always waiting. Always literal.
