| Definition |
Any system or device connected to a network is also called a node. For example, if a network connects a file server, five computers, and two printers, there are eight nodes on the network. Each device on the network has a network address, such as a MAC address, which uniquely identifies each device. This helps keep track of where data is being transferred to and from on the network. A node can also refer to a leaf, which is a folder or file on your hard disk.
Node is a Database concept associated with document-oriented storage, where information is organized in flexible document structures rather than only fixed relational tables. In MongoDB contexts, the term may also reflect platform-specific behavior or documentation conventions.
Nodes is a Cloud container or Kubernetes concept used to package, schedule, run, or manage application workloads across distributed infrastructure.
