A node is a physical gadget which is present in any network of different instruments that is ready to send, get, or forward data. A PC is the most well-known node. It's known as the PC node or web node.
Node inside a PC system must have some type of distinguishing proof, similar to an IP address or MAC address, for other system gadgets to remember it. A node without this data, or one that is disconnected, never again works as a node.
