How do I deposit money into crypto exchange?

Hello there, I'm curious about how to deposit money into a crypto exchange. I've heard that it's a straightforward process, but I'd like to know the specific steps involved. Do I need to LINK my bank account to the exchange? What about credit or debit cards? Are there any fees associated with depositing funds? And how long does it typically take for the funds to appear in my exchange account? I'm eager to start trading, but I want to make sure I'm doing it the right way. Can you help me understand the process?
