Example Application
A company wishes to provide data separation and security between network traffic from its various departments by creating separate logical networks for each of its departments dispersed throughout the enterprise, while using only one corporate physical network, which is VLAN-aware. A network administrator assigns a unique VLAN to each department. Edge switches on the corporate network are configured to insert an appropriate VLAN tag into all data frames arriving from equipment belonging to a given department. After the frames are transmitted on their respective VLANs through the corporate network, the VLAN tag is stripped before the frame leaves the VLAN-aware corporate network, and is sent to its destination, which is another computer belonging to the same department.

Famous quotes containing the word application:
“By an application of the theory of relativity to the taste of readers, to-day in Germany I am called a German man of science, and in England I am represented as a Swiss Jew. If I come to be regarded as a bête noire the descriptions will be reversed, and I shall become a Swiss Jew for the Germans and a German man of science for the English!”
—Albert Einstein (1879–1955)
“Great abilites are not requisite for an Historian; for in historical composition, all the greatest powers of the human mind are quiescent. He has facts ready to his hand; so there is no exercise of invention. Imagination is not required in any degree; only about as much as is used in the lowest kinds of poetry. Some penetration, accuracy, and colouring, will fit a man for the task, if he can give the application which is necessary.”
—Samuel Johnson (1709–1784)
