Topology
1. Physical Topology: The configuration of network nodes and links. Description of the
physical geometric arrangement of the links and nodes that make up a network, as
determined by their physical connections. 2. Logical Topology: Description of the
possible logical connections between network nodes, indicating which pairs of nodes
are able to communicate, whether or not they have a direct physical connection, etc.
Examples of network topologies are as follows: Bus, Ring, Star, Tree.
TPBus
CEBus acronym for the Twisted Pair Bus.
Transducer
A device for converting energy from one form to another, such as optical energy to
electrical energy.
Transmitter
A device which converts an electrical signal to wave energy such as optical signals,
radio waves, etc.
Twisted Pair
A common media used for telephone, networking, security, HVAC and other low
voltage applications.
UPS
Uninterruptible Power Supply.
Upstream
TV Signals generated within the house to be used inside or sent outside of home.
UTP
Unshielded Twisted Pair - Two wires twisted around each other to help cancel out any
induced noise in balanced circuits. An unshielded twisted pair cable usually contains
four pairs of wire in a single cable jacket.
Video Tele-
conferencing
Allows people in remote locations to get together for face-to-face conversation without
the expense of airfares, hotels, and lost time.
Wavelength
The distance a signal travels in a signal cycle.
X-10
Home Automation Protocol. X-10 transmitters broadcast a 5 volt 212 Khz, 1 msec
burst at the zero crossing of the 60 Hz AC power cycle. An X-10 signal occurs 3 times
at different angles. An X-10 message includes a start code, letter code, and a number
code.
