What is Nodes?

In the context of computer science and networking, "Nodes" generally refers to fundamental units within a larger structure. Their specific meaning depends on the field. In data structures, a node is a basic unit containing data and links to other nodes (e.g., in linked lists or trees). In networking, a node is a connection point, which can be a computer, router, or other device. In distributed systems, nodes are the individual machines that collectively perform a task. Their use is fundamental to building complex data structures, networks, and distributed applications.
