To explain VLANs in its simplest form. Compare the local area network(LAN) as a binder containing all the documents/data, we'll have to makebelive that this binder can be huge. Since a single binder with hundres or tousands of unsorted documents can be difficult to work with you usally place an index in the binder. Now compare each part of the index as virtual local area networks(VLANs) with the same capacity as the binder itself. The index segments the documents/data from eachother to make it easier to find and work with, anyone can view any of the sorted documents/data in a quick and easy fashion.. Now with VLANs also comes the added security, compare this as a keylock per index. So if you dont have the key for that specific index you won't be able to view or work with its contents. This makes it easy for a CFO to have a single binder for all of the companies finance-staff to work with, but at the same time make sure that critical documents/data can only be accessed by authorized personell. That ought to explain it to someone that isn't 20 at least... a CFO ought to be at least 40 i guess and hopefully knows what an indexed binder is... :) ?
