How do I know what node is broadcasting my transaction to the network? how can i get more information about this node? for example, how do i know if the node is a geth or parity node? does it matter?

You're missing the blockchain concept.
Transactions are processed on all nodes. Mining determines the order of the transactions all nodes eventually agree on. This is not the same thing as a node running transactions and the rest of the network accepting its findings.
My answer over here may shed some more light on this. how blockchain can handle the concurrency?
Hope it helps.

this is very helpful, thank you. i am wondering, though, about the pre-accepted transactions. to restate my question more clearly, there has got to be a node that picks up my transaction first, correct? Is this the node closest to me? when i send my transaction to the network through metamask, where does it physically go? do the popular nodes (metamask, mycrypto) have known physical locations?

Several details to unpack. Generally, your request goes to your own node which then broadcasts to others that you want to do something. Getting picked up in a block by a miner is the critical step to have done something. MetaMask uses the Infura backend which is a web service with a known endpoint. Infura is an alternative to running your own node. Commented Dec 1, 2018 at 18:43
