Does Polkadot account needs activation Or Not?

[LordMiguel]

please i am not conversant with Polkadot. i found it difficult to understand but recently, i am beginning to gain little idea and knowledge on how it works. there are different Networks on the polkadot domain and each shows different address. sometimes people might get confused especially when address changed.
My question: do i need to deposit polkadot token to my address for activation or i can just send other tokens to my polkadot account.

your help is needed.
