This week's tips:
Composite Signal - Also referred to as a direct video connection, it typically uses an "RCA" pin jack to connect a VCR, DVD player or satellite box. The video signal is separated from the audio signal which improves the picture performance when compared to a simple RF, or coaxial, connection.
Cut - One of the four C's of diamond quality. Also a portion of a diamond parcel split at a random point rather than by selection. Used when a buyer wishes to buy a smaller parcel than is being offered by the seller.
Fan Switch - A normally open switch that closes at a preset temperature. It causes the furnace to run for a short time after the thermostat opens, allowing the furnace to cool down.
Vegan - A person who does not eat meat or any animal products, including bacon, cream, eggs and milk.
checksum - Value used to detect transmission errors when data packets are sent from one host to another. Typically, the sending host computes the checksum for a transmission and appends the information to a packet when transmitting. The receiving host recomputes the checksum value and compares it to the value sent. If the calculated value does not match the received value, the packet is corrupted and is usually discarded
prepaid - a term denoting that transportation charges have been or are to be paid at shipping point.
