Electrical termination of a signal involves providing a terminator at the end of a wire or cable to prevent an RF signal from being reflected back from the end, causing interference. The terminator is placed at the end of a transmission line or daisy chain bus (such as in SCSI), designed to match impedance and hence minimize reflections of the signal. Often the terminator is a resistor. There are also active terminators which contain an electric circuit to perform the same basic function.
"Electrical termination" sometimes refers to manufacturing operations which connect wires together. This includes crimping, soldering, and related operations.
