Since the current network settings define one slot per second and each block that reaches a node was created for a specific slot, the local node can determine how "on time" the block arrived.
Let's first define a common understanding of the block distribution process before we get into the meaning of these new metrics:
Each block-generating node, ...

The answers are yes, and yes, respectively.
Cardano is unique in the L1 space in that it has been designed from the start to scale with the number of unique participating nodes, rather than with the hardware capabilities of the whole constituency. For this to work, a separation of the settlement and computation layers is necessary. Until very recently, most ...

A relay is a full node. I thibk what you're asking is how can I have a light wallet like experience with cardano-cli and the answer to that is you can't; however you can use something like blockfrost API to get the same type of information cardano-cli can provide.

You definitely need to have a local running cardano-node so the cardano-wallet server has something to talk to/query. Once you have that set up, the easiest thing is to download the latest pre-compiled cardano-wallet binaries from IOHK's github.
Extract the cardano-wallet binaries and place them in your bin folder. You should be able to run cardano-wallet -h ...

The correct answer is any version (that works!). Anybody is able to pick what they want. What matters is what you have in this case. If you feel your version is off, just download another one (Releases!), install it and run it!

To build cardano-wallet from sources you need first to have cardano-node, as stated here:
https://developers.cardano.org/docs/get-started/installing-cardano-wallet/
This guide assumes you have installed cardano-node and cardano-cli into your system. If not you can refer to Installing cardano-node guide for instructions on how to do that.
You should have at ...

As the other answer says there is no real difference, a cardano-node is just configured to become a relay, its the same thing underneath.
If you build cardano-node from source, then you can control the number of threads used to compile with the standard -j flag, -j8 being 8 cores, more cores = more RAM needed. https://github.com/input-output-hk/cardano-node/...

Depends on how you started the node. If it was started as a systemd service, you'd run the following: sudo systemctl stop <NODE_SERVICE_NAME>
If the node was started using the raw cli command cardano-node run, then you can just run ctrl-c in the same terminal that the node is running in, and it will perform a graceful shutdown.

Your wallets have nothing to do with your cardano-node instances or binaries on a machine.
Having the wallet keys on a linux instance on AWS that is running cardano-node (and I assume has a public IP address) is from start a bad idea. Your keys should stay only on a computer where only you have access, in your home, and also as encrypted backups on USB ...

Coincashew's guides are super helpful, especially this one on how to update a stake pool.
In short, you can either download the cardano-cli binaries directly, or build the new release from source in the same git directory as you built in the first time. Just make sure to rename the builds accordingly, and when you are done building, sudo cp the binaries into ...

You can also check the logs on your block producer or on a relay.
This is how a slot battle looks like in the logs (it happened less than half an hour ago):
