Can you sell ETH for USD?

Could you please elaborate on the process of converting Ethereum (ETH) to US dollars (USD)? I'm interested in understanding the steps involved in selling ETH and receiving USD in return. Could you guide me through the necessary platforms or exchanges that facilitate this transaction? Additionally, are there any fees or commissions associated with selling ETH for USD? And how does the exchange rate for this conversion typically work? I'm also curious about the security measures taken to ensure the safety of my transaction. Could you provide some insights into these aspects? Thank you for your assistance.
