Information AboutTermination |

Termination as a technical term has different meanings. In Electronics , it refers to the need to put a ''terminator'' (either a Resistor or a resistor- Capacitor network) on the unconnected end of a Transmission Line , to prevent signal reflections due to the Impedance Mismatch between the line and the empty space beyond its end. In Computer Hardware in particular, terminators are needed in many Bus -style communication channels, such as thin-wire Ethernet and SCSI . Some devices that attach to such channels are ''self-terminating'': they are capable of sensing whether a terminator is needed, and configuring themselves accordingly. In Computability Theory and Computer Programming , a crucial part of the definition of an Algorithm is that it must terminate—that is, produce its answer after running for a finite number of steps. Whether this number is or isn't too large for practical execution of the algorithm on a real computer is the subject of Computational Complexity Theory . In Numerical Analysis , most computations involve working with Real Numbers , which is a feat provably beyond the capabilities of Finite-state Machine s (which is what all practical Digital Computer s are). In essence, the problem is that an algorithm for computing a real number to infinite precision would never terminate. However, practical algorithms can all be shown to Converge , thus, they can be made to terminate simply by accepting a limit on the achievable precision of the computation. In VOIP telephony, termination refers to placing calls that terminate in the PSTN public switched telephone network. See Origination SEE ALSO |
