| Network Topologies |
| The geometrical arrangement
of computer resources, remote devices, and communications facilities is
known as network topology. More specifically, a computer network is comprised
of nodes and links. A node is the point of any branch in a computer network and can take the form of a computer, a terminal device, a network station, a miscellaneous device, or an interconnecting equipment facility. A link is a communication path between two nodes. - The terms "circuit" and "cannel" are frequently used as synonyms for link. When a computer network is designed, its topology is determined by the following considerations: functional objectives, reliability requirements, and operational costs. The most common LAN topologies are the ring, the star, the bus, and the mesh. |
