The capability of any system to continue functioning after some part of the system has failed. RAID is an example of a hardware device that provides fault tolerance for hard drives.
Shielded Twisted Pair (STP)
A cabling for networks composed of pairs of wires twisted around each other at specific intervals. The twists serve to reduce interference (also called crosstalk). The more twists, the less interference. The cable has metallic shielding to protect the wires from external interference.
Radio Grade (RG) Ratings
Ratings developed by the U.S. military to provide a quick reference for the different types of coaxial cables.
A light distortion problem unique to multimode fiber-optic cable.
Single-mode fiber (SMF)
Fiber-optic cables that use lasers.
Multimode Fiber (MMF)
Type of fiber-optic cable that used LEDs.
LEDs (Light Emitting Diodes)
Solid-states devices that vibrate at luminous frequencies when current is applied.
The external plastic covering of a fiber-optic cable.
Gives fiber-optic cable strength
The part of the fiber-optic cable that makes the light reflect down the fiber.
The central glass of the fiber-optic cable that carries the light signal
Electromagnetic Interference (EMI)
Interference from one device to another, resulting in poor performance in the device's capabilities. This is similar to having static on your TV while running a hair dryer, or place two monitors too close together and getting a "shaky" screen.
