Advantages of ring topology: Some features of ring topology are: Cost-effective: There is no need for a server computer to make the network. Some pros and cons of ring topology are explained below:-. The major impact was on a few target species, such as Red stinkwood (Prunus africana) (70% of 10 recorded stems), Black stinkwood (O. bullata) (57% of 359 recorded stems), Assegai (Curtisia dentata) (60% of 50 recorded stems), and Cape beech (Rapanea melanophloeos) (39% of 124 recorded stems). WebDisadvantages of Ring Topology 1) Each packet of data must pass through all the computers between source and destination. Trees of species in which the wounds do not recover easily could be cut in a selection system, to use all bark on the stem and branches.
