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).
In the mks system, permittivity Îµ and the dimensionless dielectric constant Îº are formally distinct and related by the permittivity of free space Îµ0; Îµ = ÎºÎµ0. In the centimetre-gram-second (cgs) system, the value of the permittivity of free space Îµ0 is chosen arbitrarily to be 1.
