Anyone here understand how nodes work and the operations surrounding them? Just curious not sure if this is the right place to post or not.

If you have once joined a relay race. You will be able to imagine how nodes work. You are passing a baton to a compatriot and then he will pass the baton to the other. That is what nodes do. It relays all information that is passed through it.

A node which relayed “all information that is passed through it” would be worse than useless.

A node receives what purports to be a baton, supposed to be of solid gold. But the baton is received from an untrusted source. It could be made of fool’s gold—or it could be a stick of dynamite with a lit fuse. The node examines the baton, performs laboratory assays on it, and absolutely verifies its characteristics. If and only if the baton passes all tests, then the node accepts the baton into its internal databases and passes on copies to others.

Any specific question you have?
It is just about relaying a blockchain and unconfirmed transactions. That is pretty much their job.

Not so. Nodes validate the data they receive against consensus rules. That is the most important part of a node’s job.

Nodes are responsible for securing the validity of the network, as well as the validity of their own databases. That is why running your own full node is the most secure way to use Bitcoin—really, the only secure way.

To fill out this explanation, miners have one and only one function: To determine the ordering of transactions in a Byzantine fault-tolerant distributed database with no central authority. That is what miners do. That is all miners do. Granted, it is a very valuable function; that is why they get paid for it. But all other functions in the security and validity of the network are done by nodes. The nodes’ responsibility includes enforcing validity of blocks, in case miners create invalid blocks. Nodes do not follow the chain with the most proof-of-work: They follow the entirely validated and valid chain with the most proof-of-work.

Nodes transmit information, for blockchain nodes to connect each other it query the DNS using a number of "DNS seeds," which are DNS servers that provide a list of IP addresses of bitcoin nodes. Some of those DNS seeds provide a static list of IP addresses of stable bitcoin listening nodes. Some of the DNS seeds are custom implementations of BIND (Berkeley Internet Name Daemon) that return a random subset from a list of bitcoin node addresses collected by a crawler or a long-running bitcoin node. The Bitcoin Core client contains the names of five different DNS seeds. The diversity of ownership and diversity of implementation of the different DNS seeds offers a high level or reliability for the initial bootstrapping process. In the Bitcoin Core client, the option to use the DNS seeds is controlled by the option switch -dnsseed.
