While you are documenting your current network environment, take special note of areas where you are currently experiencing problems. If you stabilize your network before deploying a new operating system, deployment and troubleshooting will be easier, and you can have increased confidence in the upgraded network.
Permittivity, also called electric permittivity, is a constant of proportionality that exists between electric displacement and electric field intensity. This constant is equal to approximately 8.85 x 10-12 farad per meter (F/m) in free space (a vacuum).
A vacuum, by definition, has a permittivity value of one, and it is this value that is used as the denominator in the ratio. The dielectric constant is used to characterize capacitors, which are capable of storing electric charge.
