What are the three basic elements that all networks are made of?

The three basic elements that all networks are made of are nodes, links, and protocols. Nodes represent the devices or endpoints on a network, such as computers, smartphones, or servers, which are responsible for sending, receiving, or processing data. Links are the connections that allow these nodes to communicate with one another, including both wired connections like Ethernet cables and wireless connections such as Wi-Fi. Protocols define the rules and conventions for communication between devices on the network, ensuring that data can be transmitted reliably and understood by all participants in the network.

This combination of nodes, links, and protocols is fundamental to the functioning of any network, forming the backbone of data communication. Understanding these elements is essential for anyone involved in networking, as they help clarify how information is shared across different devices and infrastructure.
