DOCSIS (Data Over Cable Service Interface Specifications)
– A project with the objective of
developing a set of necessary specifications and operations support interface specifications for Cable
Modems and associated equipment.
F Connector

Key exchange
- The swapping of mathematical values between entities on a network in order to allow
encrypted communication between them.
MAC Address
– The permanent “identity” for a device programmed into the Media Access Control layer
