Examples of Network Elements
With structuring and grouping, it is very well seen that in any distributed network there are devices performing one complex function. At that, those devices can be placed in different locations. A telephone exchange is the most typical example of such a distributed group of devices. It typically contains subscriber line units, line trunk units, switching matrix, CPU and remote hubs. A basic telephone service leans on all those units, so it is convenient for an engineer to manage a telephone exchange as one complex entity encompassing all those units inside.
Another good example of a network element is a computer cluster. A cluster can occupy a lot of space and may not fit one datacenter. For enterprise solutions, it is common to locate cluster nodes in different locations, even in different regions (settlements).

Famous quotes containing the words examples of, examples, network and/or elements:
“It is hardly to be believed how spiritual reflections when mixed with a little physics can hold people’s attention and give them a livelier idea of God than do the often ill-applied examples of his wrath.”
—G.C. (Georg Christoph)
“In the examples that I here bring in of what I have [read], heard, done or said, I have refrained from daring to alter even the smallest and most indifferent circumstances. My conscience falsifies not an iota; for my knowledge I cannot answer.”
—Michel de Montaigne (1533–1592)
“A culture may be conceived as a network of beliefs and purposes in which any string in the net pulls and is pulled by the others, thus perpetually changing the configuration of the whole. If the cultural element called morals takes on a new shape, we must ask what other strings have pulled it out of line. It cannot be one solitary string, nor even the strings nearby, for the network is three-dimensional at least.”
—Jacques Barzun (b. 1907)
“There surely is a being who presides over the universe; and who, with infinite wisdom and power, has reduced the jarring elements into just order and proportion. Let speculative reasoners dispute, how far this beneficent being extends his care, and whether he prolongs our existence beyond the grave, in order to bestow on virtue its just reward, and render it fully triumphant.”
—David Hume (1711–1776)
