Treetopologi

Treetopologi is a concept used in computer science and graph theory to describe a tree-based topology in which elements are arranged in a hierarchical, parent–child structure. In a treetopology, nodes connect via edges that reflect ancestry, with one node acting as a root from which all others descend. Treetopologi can describe directed trees (edges from parent to child) or undirected trees where orientation is not essential.

Key properties include acyclicity, connectivity, and a unique simple path between any two nodes. The distance between nodes is measured by the number of edges to the root, and the depth of a node is its distance from the root. In many realizations, the root is a central control point, supporting predictable routing and management. However, higher-level failures near the root can affect large parts of the network.

Variants and related concepts include rooted trees, arborescences, and general tree topologies in networking. In practice, spanning-tree protocols create loop-free treetopologies over broader networks. In computing, tree layouts underpin file systems, organizational charts, and hierarchical databases.

Applications of treetopologi span network design, distributed systems, and information organization. Advantages include simplicity and predictable routing; drawbacks include limited redundancy and potential bottlenecks at the root. The term is often used interchangeably with tree topology, though some contexts distinguish mathematical trees from practical network layouts.
