Are there difference in normal token transfer events and ERC20 Token transfer events?

So I learnt that ERC20 tokens have Transfer and TransferFrom event. From my understanding Transfer event is when a transaction comes from an address to the smart contract instructing the transfer of some of its tokens to another address. TransferFrom, comes from an address that has been pre approved to transfer tokens from another address.

Here are my questions:

• What event is triggered when normal transfer of Eth from one account to another account occurs?
• What example are there on how to subscribe to these events using the JSON_RPC endpoints? Is subscribing to ERC20 token events different from subscribing to normal Ethereum transfer?
  
• How will same transactions look like using a library like ethers-rs
