Firewall: A combination of hardware and software that separates a Network into two or more parts for security purposes.
Fibre: Fibre provides high performance speed and reliability. Fibre, or “Fibre-Optic Communications”, harnesses the fastest thing known to man; light. High-tech equipment transmits data via pulses of light beamed through tiny optical fibres, similar in appearance to strands of glass. As the signal can travel for long distances without weakening or being distorted this is also perfect for reliability.
