Network Topology
  • The geometric arrangement of nodes and cable links in a local area network. Network topologies fall into two categories: centralized and decentralized. In a centralized topology such as a star network, a central computer controls access to the network. This design ensures data security and central management control over the network's contents and activities. In a decentralized topology such as a bus network or fine network, no central computer controls the network's activities. Rather, each workstation can access the network independently and establish it's own connections with other workstations. (QCUD+Pf-90.
  • The specific physical (real) or logical (virtual) arrangement of the elements of a network. Note: Two networks have the same topology if the connecting configuration is the same, although the networks may differ in physical interconnections, distance between nodes, transmission rates, and signal types. See topology. See also bus topology, logical topology, physical topology, ring network, star topology, tree topology.
