Nodes decides if the transaction is valid before miners can get it. Miners can send back blocks to the nodes to be verified. The validity of the consensus is decided by the nodes because nodes are unable itself to make false transaction or in simple words, nodes can’t tell lies.

Full Nodes can verify the whole consensus of the blockchain. That’s why you need a power server for this as information in the blockchain will grow bigger and bigger.

Light Nodes only used relevant part of Full Nodes which you need. For example, sending and receiving money. Trust from both nodes is necessary because it sends and receives verification from full node back to lite node and vice versa

Where can I find out more about this? At present, the term "Light node" is not clear to me.

You need to find out more information about Nodes. on bitcointalk or google!
Nodes works for blockchain protection and reduces transaction time!

what is "Light node" - again?
As I understand a light Node doesnt fully download the full blockchain, it uses a method of simplified payment verification  to verify transactions. they are "connected" to full nodes to connect to the Bitcoin network

A node is a device on a blockchain network, that is in essence the foundation of the technology, allowing it to function and survive. The role of a node is to support the network by maintaining a copy of a blockchain and,to process transactions.Each cryptocurrency has its own nodes, maintaining the transaction records of that particular token. This makes cryptocurrencies running on blockchains to avoid incidents like hacks, power failures, or systemic crashes.

  I hope we know that each cryptocurrency has its own nodes .Nodes are essential because it maintains the integrity of blockchain. A light node works containing partial blockchain history they are linked with full nodes. Full nodes is a list of complete single transaction which is occurred on a blockchain.

"Node is an interesting thing to know. I know a little bit about this. Can anyone explain with a possible example with easy description about what is it, how it works, how many classification it has ? I found some explanation which may help, I assume :

Nodes are distributed servers or computers that performs validation of every transaction on the network. These nodes are the one securing the blockchain to avoid tampering of data by having a copy of the original data for validation.

nodes are unable itself to make false transaction or in simple words, nodes can’t tell lies.

there is nothing stopping a node from "lying" so they can technically "lie". it is every node for itself and the whole network that decides the consensus rules and rejects anything that is invalid.

Where can I find out more about this? At present, the term "Light node" is not clear to me.

it is not clear because OP is making it complicated and this whole topic is silly!
to understand what bitcoin Full Node is you should simply read trusted and well written sources such as bitcoin wiki: https://en.bitcoin.it/wiki/Full_node
that article also includes information about "lightweight nodes" aka SPV clients. also https://bitcoin.stackexchange.com/questions/4649/what-is-an-spv-client

The main purpose of nodes is to maintain the integrity of the blockchain for a certain cryptocurrency. The whole blockchain record can be preserved even if there is just one node running it, from any place in the world. This makes cryptocurrencies running on blockchains to avoid incidents like hacks, power failures, or systemic crashes.

The OP's description seems confusing. I'll try providing a better summary.

Full-Node

A full-node is the term for "fully validating", which means this type node checks both transactions and blocks itself, without trusting others to do that. Note that miners will usually be full-nodes, because if they don't they risk losing money as they might waste hash power on an invalid block.

Light Node or SPV (Simplified Payment Verification) Node

A "light" or "SPV" node does not verify all transactions or blocks independently. Instead, this type node relies on other nodes to check whether or not transactions it is concerned with are in the valid blockchain. In many situations this reduced independence is fine for making simple transactions, and this type node uses far less resources since it doesn't deal with entire blocks.

An example of a popular Bitcoin SPV wallet is Electrum: https://electrum.org/

The advantage of using both types is completely controlling your own private keys, which is recommended (as opposed to leaving coins on exchanges).

I didn't understand node properly before but you explained it in an easy and very simple way, thanks to you. Nodes are an important member of the blockchain system that decides whether a transaction is valid or not. Full nodes are those that verify the whole data of the block and light node verifies a small amount of block data.

Usually, node can be any active electronic device, including a computer, phone or even a fax machine, as long as it has internet connectivity and has an IP address. A node supports the network by maintaining a copy of a blockchain and, in some cases, to process transactions. Nodes are reason why data can't get lost.

Node is an important device in blockchain network and it is able to carry out several types of tasks. Best part of it is that it can be connected from both desktop and phone or even from printer.

Yes I think nodes are very important device for blockchain. You can active it at any time all you nedd to have is internet protocol address that means internet connection. It maintains transactions records and tokens as well of cryptocurrency.

Nodes are undoubtedly essential tools. It helps in processing of the transactions of crypto currency and also determine the validation of these transactions including maintaining it’s records. So functions of nodes are really useful for blockchain.

"Bitcoin which does not require a set amount of it’s coins to be used as collateral
in order to qualify as a full node, Dash requires you to have 1000 of it’s coins to
qualify for a master node, in return, Dash allocates 47.5% of it’s block reward to
go to it’s masternodes. The 1000 dash coins remain in the persons possession,
there is no need for you to transfer your private keys, and at any time you can
remove yourself from the master node by reclaiming your collateral of the 1000
dash.
