How do I send ETH to someone?

Could you please explain to me the process of sending Ethereum, or ETH, to someone else? I'm a bit new to cryptocurrency and would appreciate a step-by-step guide on how to safely and efficiently transfer my ETH to another person. Is there a specific platform or wallet I should use? And are there any fees associated with the transfer? I'm looking to make sure that the entire process is smooth and secure, so any tips or precautions I should be aware of would be greatly appreciated.
