One of the three principle nodes making up a domain (in KeyKOS for the S/370); specifically, the node which contains such keys as the address segment key and meter key. See "Domain key".
The root node is the tree node that has no branches leading to it from other nodes. A root has no parent node. The root is usually used as the label for whole tree.
A distinguished node in a tree that has more than one connecting edge. In particular, in a directed tree the root node has an arbitrary number of outgoing edges and no incoming edge. See Also Tree.
A node within an HP XC system that is connected directly to the Root Administration Switch.
a node that has no parent node
a node to which all other nodes in the tree structure are conceptually connected
The top-most node in a tree structure. If the tree structure represents a well-formed XML document, the root node will have exactly one element node, representing the document element, and no child nodes. It may also contain comment nodes and processing instructions nodes as children.
hierarchy node to which all elements belonging to a given category are added. For example, hierarchy node named Chemistry might be a root node of all elements belonging to chemistry
In a graphical representation of data as a tree, a node that has no parents but typically has children. (Back to the top)
The root node is the unique node that is not a child of any other node. All other nodes are children or other descendents of the root node. [ XML
A node within a scene graph that establishes the default environment. See also group node, leaf node.
The first index node in a B*-tree.
