How do I buy and send TRX?

Could you please explain to me, in simple terms, the process of purchasing and sending TRX? I'm new to this cryptocurrency stuff and want to make sure I understand all the steps involved. Also, could you tell me which platforms or exchanges are reliable for buying TRX? Is there a specific wallet I should use to store and send it? And finally, are there any fees or charges involved in the transaction? I'd really appreciate your help in clarifying these things for me.
