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. Thus, the permittivity Îµ and the dielectric constant Îº in the cgs system are identical; both of them are dimensionless numbers.
